speaker intall question

hey all, tried askin this on sounddomain but i cant get the forum register to work. so eh, here we go. puttin together a 8 speaker sound system, and got a question, the way im lookin to wire the speakers up, its going to either drop the ohms from 4 to 2, or raise them from 4 to 8. im looking at the 2 ohm setup, by wiring the speakers in parralel. i have all the specific numbers if yall need em. but i just want to know if i might damage the speakers by running them in parralel at 2 ohms instead of the 4 they are rated at. anybody have a clue??

umm i dont think it will hurt them as long as you dont go over the rated ohms

ive ran home speaker in a truck, i think they were rated at 8 ohms, i didnt have a problem

yeah i asked my bro, and he thinks the weak link would be the headunit, by dropping the resistance to 2 Ohms, i might fry the internal amp. so looks like i might have to wire the speakers in series, but i emailed sony to find out. i think it will handle it. its a pretty serious head unit.

Dude here it is, If ur talking subs if the amp and speaker is rated to go down to 2ohms than it is fine. If not it u will mess one of them up either the amp will blow or the speaker. If u are talking about 6x9's 51/4 or basic speakers I would just hook them up direct from the deck because most decks and those kinds of speaker arn't made to run either of those ohm. U will get the best sound wiring direct K for those. If u are trying to get more bass by lower the ohms on theose speakers don't they will blow!! Also if u are looking fior bass and don't want weight or don't have enough room. I would recomend geting the bazoca 6.5 in 100watt powered bas cannon. This will wire in to ur existing speaker channels with ur speakers. It hits and sounds really good. Also it has RCA out puts so u can add amps if u ran out of RCA out puts on ur deck. I hace this 1971 Camaro and have 2 pioneer 6x9's up behind the sets and with a pioneer deck, a bazoca bas conon that one i has talking about. I just used the RCA's out of the bass cannon to go to my 800watt legacy with mu Audiobahn 10 in a band pass box it sound awsome. My deck goes up to 30 volume and I cant turn it past 14 on rap and 12 at most on rock it can defin u. Give it a try and let me know what u do.

thanx for the advice zboom, my problem is that while i have heard complaints about the sony xplods blowing out, ive been running them in my RS for a quite a while, and never had a problem. in fact, very pleased with them. also the main deal is that my car is black and red, so the black and red stereo equipment looks sweet when mounted so you can see them. im going for a very smooth, very factory appearing instalation. also not interested in subs at the moment. not really nessesary for what im into, im not trying to build a competition system. just something that will handle the music i throw at it. which the stock system, or at least the crappy system that was in teh car when i bought it, couldnt do. right now im narrowed down to wiring the system in series and taking the hit on power output, or getting an amp, im lookin at one now thats 75 watts RMS per channel at 2 Ohms, 4 channels, so ill probly bite the bullet and run that. just have to figure out where im gonna mount the damn thing so its either not visible or dosnt look tacky. probly under the storage lid in my hatchback, protected by a mesh grill. eh, didnt want one, but guess i gotta.

what about mounting it under the driver seat? and i also like the sonys

wait are you talking about where you gonna put the speakers or amp?

actually mounting under the passenger seat is a possiblity, driver seat has the power plug for the six way adjuster switch i plan on putting back in sooner or later. speaker locations are as flows,

dash 2x 4x6in speakers
doors 1x each, 6.5in speakers
sail panels 1x each, 6x9in speakers,
rear cargo cover from bose system, 2x 6.5in speakers,

so 8 in all. and the bose system cover had a hidden surprise, the stock speakers are only 4in, and actually have three instead of four screws, but the speaker covers are four hole, and are the same mounting pattern as a 6.5in speaker, ive already tested it with a older set of xplods, and they fit. so i can take advantage of teh box design bose used to make bass with the 4in speakers. :) so because i have that locking cover, i might put the amp down under it, mounted to the sheet metal against where the gas tank is, yeah yeah, ill be carfull, i wont drill into the tank. ;) that or seeing as ive already got the carpet out, ill just have mounting studs welded in so i dont ahve to drill through the sheetmetal, so if i ever return the car to stock, i can just grind off the studs, and not have damaged sheetmetal. but yeah thats what im lookin at now, ive got the bose cover mocked up, so if i can get my digial camera working, ill post some pics to show ya what im talkin about.

ooo ok, yea the sheetmetal thing sounds like a good idea, and in my maro, there a compartment in the rear on the left, right across from the spare tire, maybe that could be used for the placement of the amp

heres the pics of what im lookin to do, these sonys arent the ones im looking to use, but they are the only 6.5in speakers i had lying around to test fit.

heres how the lid looks from the factory...

heres the bottom showing the speaker boxes, that also hold the amps..

and here if you look to the right, youll see the round vent port....
http://files.automotiveforums.com/gallery/watermark.php?file=/503/114663boseside-med.jpg

so basicly this lid turns the whole trunk space into a vented box. it covers the storage well in the trunk behind the t-tops, and locks against the trim peice that covers the hatch pull down. so the sonys fit, and will look stock, and will hide the amp from prying eyes so long as i mount it down in the storage well :) as far as the dash doors and sail panels, i think everyone knows what those installations look like.

you should really check out the www.caraudioforums.com they should be able to help you out with the wiring ive learned alot about fiberglassing over there it seems to be teh best way for a sub in "our" trunks lol

ooooo ok, i gotcha now, so it just hides the hold storage area in the rear, so you got that flat part behind the seat and then it just angles up to the window right?

wait, i dont think i have that right.... or wait well shit do i

right place, wrong look. the bose lid dosnt angle up like the ones on the fourth gens, if you take the flat part of the trunk where the T-tops sit, and just keep it going strait back so that it hits the rear trim thats where this lid goes, so its just one big flat area, with the storage well under the flip up lid. thats what this will look like. currently the IROC is dead in the water at work with a VATS problem, so i dont have it here to mock it up, but when i get her home ill lay the lid down in there and put up a pic of what it will look like, cuz to be honest, im kinda curious myself.

oooooo ok i gotcha, that will look nice,you might have said already but im too lazy to go back up and re read but where did you pick up the lid from?

www.fbodymotorsports.com

when i drove down there for my mass parts buy i happend to ask about it. they had two lids when i was there, this was the better of the two, the other one looked like it had been left outside for a while. hinge was rusted solid and the screws were a bit coroded, and didnt know the shape of the speakers or amps, not like im usin em anyway, but im puttin em in a box for safe keeping. but they do have another lid down there probly worth saving. sadley they didnt have the bose kick panels. so im still out shopping for those. id rather use them to install my speakers than cuttin up my doors, but well see. my lid with the wiring harness to the speakers back to almost exactly where my orignial harness was cut was also included, but i dont think the lid they still have had the harness. but if your doin aftermarket installs anyway, you wont need it. ive also seen these lids on ebay. but i got mine cheaper. still gotta look on ebay for the kick panels though.

hmm.... im going to look into getting some those.... i jsut took out my dash speakers the other day, they were polk audio speakers, i dunno if those came factory or not, i dont think they did

naw, stock speakers were either Delco brand, or bose, at least for our years, monsoon came out in the fourth gens. anything other than that, and its aftermarket. i put the xplod 4x6 two ways in my dash and love em. never looked back. and you can even sorta see em through the grils in tehdash pad.

Are you using the amp to power all 8 speakers or are you using the head unit to power some? Also are you planning to mount the amp upside down on that lid? I can help you with your wire scheme, I am just unclear as to what you want to power.

lol, yea i like the sonys, like you said they match my interior, red and black, have sonys in the side panels right now,6 by 9s, and i was thinkin bout gettin them for my dash or putting the polks back in there, ive heard polks are pretty good too and they sounded nice, i had subs in my rear, i ad a custom box with 3 10in sonys, and 2 400 watt amps, and a ok headunit, it sound kick ass, at the moment i have it in my bronco and ive upgraded to a 1600 watt amp, and i have the sony flip face cd player in there, its sounds really nice, i plan on puttin it all in my camaro when i get her drivin again

i cant stand sony car audio. there's so much stuff that is so much better and so much cheaper...

gobears, well i was originally looking to power all 8 speakers on a single head unit, no amp, but found out that id either cook the head unit by wiring the speakers in parralel, two per channel, dropping the resistance to 2 ohms, or id get no power, wiring speakers in series, two per channel giving me 8 ohms resistance. so im looking now at a 4 channel amp, that is 2 ohm stable, and puts out 75 watts per channel at that resistance. RMS. so ill be mounting the amp in the storage well against the wall facing the fuel tank more likely than not. doin my best to avoid cuttin up the original bose decklid, no mounting holes or anything. so ill just have more wiring than i was previously looking at, no biggie. run the RCA cables from the front to the back, then run the speaker wires from the back to the front, pretty much a no brainer, especially seeing as i have the carpet out of the car right now. :)

haha yea run like a bunch of wires everwhere just so if you need to use them in the future theyll be there ... lol

That will work, just don't forget that even though an amp is 2 ohm stable it is going to work much harder to put out its rated power, at a 2 ohm load. In that well there will be no air circulation and the bottom of that well is close to the muffler/exhaust. Almost all newer amplifiers have thermal protection and will shut down when overheated but damage can still result. If you are like me and love your music loud, that amp will get hot quickly especially at a 2 ohm load. If you intend on summer cruising for extended periods at a high volume level, I would suggest a couple of inexpensive 12 volt fans to help draw/expel fresh air into that well or at least to get some air flow over the cooling fins. One more tip, when mounting your amp on that incline, mount your amp vertically instead of horizontally, mounting your amp that way will help the amp's cooling fins dissipate heat. I do alot of installs as a hobby of mine, so I would be glad to provide any help I can.

yeah i had thought about the heat situation. fans arent a bad idea. that or ill make the amp waterproof and throw a bag of ice on it everytime i get on the road for a long trip :) but yeah, the heat is a problem ill have to address im sure. especially with the lid on there. BLAST foiled again lol. eh, drawing board is still open. ill think of something yet :)

the monsoon kicks @$$

i got one of those pioneer double dens to go in my rs
and replaced all my factory speakers
with pioneer ones and put a 300w amp in the
little locked compartment in the truck and
i had a box made for the rear well and put
2 12's in there its an awsome system.

huh?

ohok, now i get where the monsoon came from but yes, that system does kick ass.

do you guys (with the subs) have mad rattles? im gunna make a fiberglass box for 2 12's but was wondering how bad the rattles might be , i realise its differnt with everycar but do yours?

well the third gens do have alot of rattles, all i did was put the xplod 6x9's and 4x6's in my RS with a shitty jensen head unit. and i had to take two days to play high volume rap music with alot of bass, and track down all my rattles, screwed several trim panels together, put rubber hose around metal peices that screwed together, and other creative solutions to body rattles. youll probly also have to go around and tighten all the bolts on teh dash and everything, for screws that keep coming out, a little electical tape around the theads will help it stay in place when you screw it in. i only use that for trim screws though.

so i guess to answer your question, yeah if you put subs in the car youre gonna have to go on rattle patrol, and fix em all, unless the sound of the subs drowns em out :)

Well what year camaro do u have?
I have a 1971 and a 10 with a 800 watt amp and it don't rattle to much

Use Dynomat!!!

Like Joseph said...pull your panels and Dynamat everywhere you can. Not only will you gain valuable decibels to your audio system, but you will cancel an unbelievable amount of exterior noise.

this is true, but at least with my to girls, there are also alot in intereor rattles, trim panels buzzing together and such. one really annoying one i had to track down, took me forever are the vents in the door jams. they have a rubber flapper gasket that allows air out, but not in, and its right next to where the 6x9 is, so when the 6x9 starts goin, the air pressure in that section starts going up and down, and that rubber flapper starts buzzin like a bee inside the body pannel. took me three days to figure out what it was. wound up rippin all the rubber out of em and puttin em back on :) but like i said, if you got a third gen, be prepaired to hunt down and be creative in solving interieor noises.

i dont have any rattle problems, i only had a few pieces of dynomat and i didnt have any rattle problems when i had it in

i had an epiphany today. or at least an idea. tell me what you guys think. ok the head unit only handles 4 ohms resistance right? so to wire my speakers in paralell would drop the resistance to 2 Ohms, cooking the head unit. why cant i do this, and also wire a 2 Ohm resistor in-line to raise the resistance back up to 4 Ohms so the head unit would be ok???????? anyone think that idea would work?? im still fighting the idea of using an amp, just cant really afford one, and dont want the hassle involved.

and also wire a 2 Ohm resistor in-line to raise the resistance back up to 4 Ohms so the head unit would be ok???????? anyone think that idea would work?? im still fighting the idea of using an amp, just cant really afford one, and dont want the hassle involved.

Hmm.. thatd be interesting.. But if you spliced a 2ohm resistor in line with your speakers, chances are it'l just defeat the purpose of running them parrellel all together?? cant say for sure.. But thats my idea..

thats the idea, i just dont want to fry my head unit, or loose power, so by using the resistor, it defeats the purpose of wiring it in parralel, and frying the headunit, and should make the head unit think its got a single speaker on the line, with 4 Ohms resistance. the only snaffu that i can think of, and ive emailed crutchfield about it, is weather or not the in line resistor will in some way negatively effect signal quality to the speakers, and thus make them sound like shit, if they produce sound at all. and if i should wire it on the positive or negative wire.

that's a weird one, I don't even know what resistors do.

personally, i think you should just pick up like a 75 to 100 watt amp, just so you dont run into any problems, and risk damaging your system, i kno some people stay away from ebay, but man i get good ass deals, and have never had a problem

?????? i stumped you on this one gen????? dude, did i just single handedly revolutionize stereo system installs the world over??????? am i really that good???? no one answer that, lemmi bask in the idea for a minute or so ;)

well i mean, yeah ive hit up ebay, and there is a 4 channlel xplod amp, 2 ohm stable, 75watts per channel at that resistance, only 150 bucks, not bad at all, but to install it, ill have to find a place, wire it in, figure out how to keep it from overheating, so that will require more work, then set it all up, and then i have to worry about blowing the speakers like everyone says xplods do when you run em on an amp. so i really would preferr to run them off the head unit if i can, easier to wire, wont push the speakers to hard, easy and effective is what i say.

check those 2 out i listen....

listed***

i'm thinkin it would just cancel it out and get no sound at all

hence the name "Xplod" huh

ridge_runner, you need AIM so we could just make this a realtime conversation, kinda like a conference

haha

are there head units that are 2ohm stable?

i have aim

ridge runner - oh man, thanx for the effort on those, but in no way am i gonna mess with a factory plug harness for a monsoon 10 channel amp like whoa :) also i dont know the specs on it, if its not kickin more than 50 watts per channel it aint worth it.

and gen, i dont think the resistor would cancel it out, unless it blocks the signal by the nature of its design. it just increases the resistance of an electrical circuit. as far as head units being 2 ohm stable. i guess thats a possiblity, but the tech help from crutchfield says that no head unit is 2 ohm stable, so i think ill trust them on this one. unless i can actually see proof that someone is running 2 ohms into a head unit. guess tomorrw ill get on sound domain and see what some of them have to say about it.

haha its all good
my aol is customx113

at this point i think im mostly just curious as to weather or not my idea will actually work. just the principle behind it. even though ill probly have to put an amp in there.

hook up 2 head units.. lol
