how to power powerful Subs

for my regenecy im looking @ 2 Pioneer 12' (http://www.pioneerelectronics.com/pna/product/detail/0,,2076_4061_153020681,00.html) subs. 1000W Rms and 3000W peak. this is @ 4ohms. What sort of amps do i need? do i need a 3000W @ 4ohm for each? or can a run a lower ohm amp? and what kind of amplifiers do yall recommend.

as far as I know, those are spl subs, which means they will sound like ass on music...they'll just get really loud

If you still want to go with them, you would want somewhere around 2000rms at 2ohm. Not too many choices at that impedance, us amps is the only company that comes to mind.

Yup, and pay absolutely NO attention to anything ever says PEAK. The only power rating for subwoofers or amplifiers that matters is RMS!

So, I'd look into something else in all honesty...

actually im thinking those woofers are dual 4 ohm, not just 4 ohm. so this means that if you had a pair you could wire them in a series for a final impeadence of one ohm. and yeah there are a lot more amps that do 2kw at one ohm. and yeah those subs are just for getting loud as balls, so if youre into shaking blocks thats cool but if you want some sound quality there are subs that will get as loud that will still sound better.

oh yeah they are dual 4, so you would wire them in parallel and get an amp that does around 2000rms at 1ohm

NOtice that you don't need the full 2kw ESPECIALLY if your not too sure of what your doing.

:banghead: shit... meant to say wire in parallel but accidently said series

oh well

anyone care to exlain exactly what that means to wire subs in parallel? prolly a dumb question but im new to this.... im jus startin to understand ohm's and everything... heh

http://www.crutchfieldadvisor.com/S-RI2QW4Uickc/learningcenter/car/subwoofers_wiring.html?subs=2&impedance=DVC4x2

check out the 1st diagram.. notice all positives are wired together and all negatives together.

basically wiring positive coils together and negative coils together to the amp. also, for every time you do this, your final impeadance is divided by two.

so in this case, you have two dual 4 ohms subs. wire the sub itself in parallel, you now have a 2 ohm load to each sub. now, wire each "2 ohm" sub together and you now have a final impeadence of 1 ohm.

sorry if its confusing, i tried to simplify it and may have ended up just making it sound weird.. im definately no electrical engineer

It means basically to connect all the positive (red) terminals on the subs to the positive connector on the amp, and all the negative (black) terminals to the negative connector. If you were to do series on a DVC sub, you'd be connecting one positive to the amp, then the negative to the other positive, and then the last negative to the negative on the amp (or the next sub if you wanted to go to 16 Ohms for some unknown reason). Somewhere in the past threads we had a whole debate about this, and I had a bunch of equations to support what I was saying. Don't feel like looking for it though.

::edit:: darn it, he beat me.

ok. how about one of these 3 sbus?

if anyone else has any ideas on subs please let me know.

and how about this (http://international.jbl.com/car/GTi/newproduct.asp?language=ENGLISH&prod=A6000GTI/230&cat=AMP&ser=GTI) amp?

how much $ do you have for this system?

seeing as i will be installing it in the future, doing reserach now i can save as long as need, but im looking @ about 2-3K on subs and amps.
anf about 600 on HU and speakers
so about 4K total

wow that's a screwed up budget if I've ever seen one

I have almost twice as much invested in the HU and front stage than the substage, and I still feel like I spent too much on the substage in comparison. You do realize that 90% of your music is being reproduced by those front speakers, and the other 10% is from the sub right? And you're spending 10x more on the substage....that makes sense.

^^^^^ Agreed...

You may want to consider balancing out your system a little more, but I guess that's totally up to you. As it is with what you're suggesting, all you're going to hear is bass. A HU cannot supply enough power to your speakers to make that setup sound even remotely decent, so maybe you should look into budgeting for an amp to power a nice set of component speakers. I usually tell people to forget about rear fill, but again, that's personal preference.

Out of those other subs you suggested, the GTi gets my vote, although I hear the Type X is also a very nice sub. A single W15GTi in a custom ported enclosure paired with a GTi component set, all powered by JBL/Crown amps would be very nice indeed... :)

I usually spend more time on the front stage of a system just because it is so much more difficult to get it right sometimes on certain vehicles.

ive been tlakign with some people and this is what im heainrg. im think im going to drop the subs for now and get a nice set of component 6X9's, a nice headunit, and a nice pair of 3 1/2's. then jsut save for a nice new car next summer.

Im looking @ different head units right now. has anyone heard anything about any of these?

JVC KD-SHX900 (http://www.cardomain.com/item/JVCKDSHX900)


im looking @ alternatives the the pioneer because i saw 3 cars with it this past week. and i like to be original. so let me know what you think.

i used to have the 2005 JVC KD-LHX500 i dont know what the difference is between it and the JVC Arsenal KD-AR5500 except it isnt nearly as much $$ also its silver and the other one is black. u can get the deck i had for 245 at allcarstereo.com. i loved this deck it had a pretty cool touchscreen. i'd suggest a alpine deck tho there very nice my dad has one.

now im looking @ one of the last 2. im leaning towards the JVC cuz i love the way it looks. but if anyone has an opnion let me know.

panasonic.. no question.. IMO panasonic is a better brand, so id choose the panasonic(if the features are about the same). plus i think it looks better than the jvc anyways..

im still teetering they both have there strong points, has anyone used either one of them? or had problems with either brand, or not had problems.

I think they all suck...honestly...

Look into:
Alpine, Clarion, Eclipse....

awww, you mean an XXX 18 and 1800w RE comps 100w....can you say...Super Over Kill? :lol2:
it this guy is like me i like to not have to hear most of the words in a rap song (especially the cuss words ever other breath, cussing i dont care about but when you do it like it is the word and, or, but, etc... it gets rediculous) then its alright, atleast i will have a bass know to turn my amp way down when listening to my beloved classic rock...

but i say 2k into sub stage and 2k into head unit, mids/highs, EQ is fine... 3k in sub stage....i dont think you realize what that will get you. for 2k you can get a pair of SX's and a 20.1 and an altinator.... get some good CDT comps or something and a good amp for them with a good Eclipse or Mcintosh head unit....you will be happy...

ive never heard of eclipse. im going to go look @ them

ive never heard of eclipse. im going to go look @ them

Do it,
The top three brands (that I can afford) that i'd put in my vehicle are what I listed before ;)

NG

im liking the eclipse, but wehre do you get them, i cant find them in any of the stores i usually look @.

and im looking @ amping a Dual 8" box (http://www.dR3x.info/images/ghetto1.jpg) that a friend of mine gave me. im thinking of getting a LOC and hooking that upto my rear speaker leads and then to a small 2ch amp and amping the 8"s. its a temporary solution, and something my mom will prolly go for, hopefully.

im kinda looking @ this
http://www.circuitcity.com/rpsm/oid/90110/originURLEncoded/http%253A%252F%252Fwww.circuitcity.com%252Frpsm%25 2FcatOid%252F-13095%252FN%252F20013088%252B20013095%252B40000659 %252Flink%252Fref%252Frpem%252Fccd%252Fcategorylis t.do/rpem/ccd/productDetailSpecification.do#tabs
its not that powerful, but i dont need a ton of power, and my friend has about 20ft of 0 gauge wire and a ton of the other stuff for instalation. i might pick it up this week.

another question, could i take a single input and split it into 4 outputs? like usinga 4 ch amp, so i could use my new 8"s and m,y 6x9's?

WTF is Verge????? Looks like another paper weight the chains are selling.

it is, i changed my mind and im looking at a cheap 2 ch amp. ima use a Line out converter to change my rear speaker wires into RCAs from the amp. this is jsut temporary. i am still going to install real shit this summer.

Werd, obviously as you should know...those 8's you listed above are complete TRASH. Feel free to come back and we can steer you in the right direction when you're ready ;)

i know, but my mom said hellz nah to anything better. im still working on the amp. its gonna be cheap. but tis better n stock. ill be around , and when i start investing ill make a new thread.

its gonna be cheap. but tis better n stock.

With crap like that, I wouldn't be too sure. The chance of it actually making your system sound worse is pretty high, and the chance of it breaking within a month or two is even higher.

Tis true, tis true!

well.. if it breaks then i jsut have to buy a new system then dont i?

Yep, then you'll be out even more $$ compared to if you'd just wait till you have the $$ for a real system.

not that muhc money, less than 100$. and i got that from the last install i did. meh, its on its way so it too late now lol.
