whats the problem?

ok my buddy just bought a 12" rockford fosgate p3 and p5002 amp. the amp puts out 500 watts@ 4 ohms bridged and the sub is a dual 2 ohm wired in series. sealed box, about .8 cu ft (rockford specs).

anyways my buddy hooked it up and i checked it out yesterday.. it sucks ass. sounds liek its not getting half the power it should be. i turned the gain up all the way and it got louder but still not as loud as it shouldve. but dont worry i put the gain back down right away.. what could be wrong with it to where its not giving output like it should?

also, dont knwo if this is realted but this kid has some serious wiring issues, first, when he took the HU wire for the remote wire, it was already connected to somethin.. he disconnected it for the remote wire and it turns out when he turned it on he lost his real speakers.. he hooked the wire back up and the speakers were on.. what the hell?? and besides this after he put the system, he cant roll down 3 of his windows. anyways figured id put his in if it makes a difference. please help if you can.

Time to buy a new HU and quit trying to run systems off of a stock HU? He probably cut the wrong wire too. He's a n00b.

well he has a panasonic, not sure what model but its not the stock radio. and as far as the wire goes im pretty sure he cut the right one but the HU is wired totally wrong i think.. not sure though you could be right..

anybody? any other suggestions?

What vehicle is this in? Is it dodge? It probably has a factory amp. just splice both wires in. I had the same prob with my boddy's 2000 ram. Installed his system turned it on and no sound. took me about two hours to figure it out. Do you hear a click when you conect and disconect the wire?

as far as the sound goes check the settings on his deck.It may have a subwoofer volume or built in filters.????????????????????????duno.

as far as the windows go if he can only control the drivers window he probably cut into the power wire that runs from the drivers door to the passengers doors. Does he have a window lock sw. on the drivers door?have him flip it to lock and see if his deck turns off.hahahahaha.

Check his wiring. check http://www.ucinet.com/~rmssound/wirecode.htm for wiring color codes and print them out for him so he doesnt burn his car up.

Things to check (some of which have already been posted, but just to reiterate)...

- pre-out settings on deck (ie if it has a sub out, check sub level; if you're using rear sp pre-out, check fade, etc)
- adjust amp gain - there's nothing wrong with having it full if you need to
- power distribution to amp - make sure buddy has wiring/fusing that will support the current draw requirements of that amp
- check impedance of sub - probably not an issue, but just in case. There is a dual 4-ohm version of that sub as well, so make sure he's got the right one

If everything seems to check out, I'd highly reccommend porting that sub. Hell, I'd reccommend that even if it was pounding nicely. I've heard P3s in sealed boxes before, and their performance is lackluster, to say the least. You need to port them to make them shine IMO.

dice daniels.. no factory amp. theres sound from speakers, sub, everything. he replaced his speakers and they worked without amp bypass so im assuming theres no amp.

" - adjust amp gain - there's nothing wrong with having it full if you need to "

um... no comment.

as for wiring, i checked impeadence and it appears to be a dual 2 ohm sub.

but im wondering if his power wire is having any affect. RF recommended 4 guage wiring for this amp and hes only got 8 guage, but for 500 watts it didnt think that this would play a huge role. maybe im wrong.

preout settings: at full, even with that and the gain all the way up it still sucks ass.

" - adjust amp gain - there's nothing wrong with having it full if you need to " LMAO, your just making yourself look like a fool already.

Anyways, 8 guage should be plenty to supply 500 watts, definelty shouldnt make that big of a difference even if not. but using 8awg i highly doubt is the problem

well if your deck only puts out .15volts then it would be all the way up.

I was always told that you should'nt run your amp too far above the normal volume mark. Causes distortion and clipping.

unless the wire is heating up I'd say its ok. Does the power light on the amp flicker alot when you turn it up?

It could also be his sub enclosure all together.
was that 8 cubes or .8 cubes?

I have had to run a second crossover before just for the bass boost.
most of the time it was because the deck had like 1.5 or 2 volt pre outs.
Most decks now days have like 5 volt and higher pre outs, sub woofer controls ,filters and some even have bass boost options. If his is pretty plain jane he may need to invest in a boost of some sort. I'm sure he cant turn any of the lows up on his deck without distorting his cab speaks.maybe it will make the difference you're looking for??????????????????????

as for the remote track it down. do some wire chasing. I was told that only "some" dodge rams have factory amps and some have a relay of sorts. My old 87 chrysler new yorker had the same little ponder and I tracked it down to a little relay box. Turns out it was a protection breaker to keep from blowing speakers. Didd'nt work to well beings the stock speaks were blown though.

you fuckin noobs. Gains are not volume knobs. The purpose of gains are to match up with the input voltage of the HU. If your Hu puts out .15 volts then the gains will be all the way up 2 volts somewhere near the middle and if it puts out 6-12 volts whatever the highest is on ur amp then the gains are all the way down.

is the amp bridged properly

Shit bro calm down!!! So what you are saying so dickishly is that if my deck has 7 volt pre outs setting my amps gain to 7 volts is safe even if it is above the little safe mark right? what if I decide to put a crossover between the deck and amp? wouldnt that change the voltage?

you're a dummy...please cease in talking!

yes go shock youself and die now PLEASE.

who the fuck are you? Insulting my intelegence. What a dick. Kiss my ass buddy!!! you're probably just some little kid with a big mouth. Let me look (yep 19 kiss my ass punk!!!) I bet you get punched in the mouth alot.Keep your punk ass comments to yourself !!

I'm not even gunna say n e thing I'll let all the members here back me up......

n00bs making themselves look stupid are so funny... dice dude, bumpin's been here for over a year, and been very active in this scene. He's always got his own opinion on what sounds good, as everyone does, but for basic amp/sub/wiring setup, there is only 1 right way to do it. Notice the "right"... there are always other ways to make it work, but they won't sound good, and probably damage the equipment. He and many other people here have done research and bounced ideas around figuring out this stuff. You really don't have anything to back you up.

Age really has no importance in this either. You know what you know by reading tons and asking questions of those who know more. I spent 3 months learning about extreme computer mods a couple of summers ago, and some of the most knowledgable people were kids 13 and 14 years old. I don't know how long you've been working on car audio, but I'm going to assume you don't get much training on the subject. Learn when to keep your mouth shut.

who the fuck are you? Insulting my intelegence. What a dick. Kiss my ass buddy!!! you're probably just some little kid with a big mouth. Let me look (yep 19 kiss my ass punk!!!) I bet you get punched in the mouth alot.Keep your punk ass comments to yourself !!

Come lick my balls little boy, you're a FUCKING MORON period when it comes to caraudio. Come around here and you'll see what happens...you'll get SCHOOLED on every aspect of the 12v world.

So, just go home to your transvestite mother and start suckin her dick again while she complains to your father about how he should have pulled out (before they had you, sorry excuse for an intelligent life-form).

Well, we both said the same thing, I just don't like to flame. I enjoy lettin others do it.

Anyone else want to burn the flame bait?

HAHAHA. You have no "intelegence" to insult

nuff said! And Noah I know its called that 12v world but in our case the stable 14.4v world!!

I'm glad you all got it out of your system. As for the training in car audio, I learned by asking alot of questions. Larned a few things from 14 and 15 year olds myself. I never said anything about age and knowledge having anything to do with each other. I was aiming it at maturity. I never said anyone was stupid. And as for me not knowing the electrical end of automotive I was ASE certified three years ago for GM electrical systems. I can wire anything, I just dont know shit about settings and building custom boxes. You can post a picture of any plug off of any GM and Chevy vehicle up to a 2000 model and I can probably tell you what year the vehicle is and what part the plug came off of. But when you start talking about spl,qms,and tuning boxes to certain hz you got me lost. Thats what I am looking into learning.

See, now this is why I don't flame people. They can be jerks one minute, then turn around and write something like this:

It's such a stark contrast to this:

that we wonder if it was written by the same guy.

Thanks for the turn around!

I got a short fuse. Dont take well to being called stupid. There has'nt been anything I havent been able to learn yet. Just need a picture or good exsplination and I'm set. I dont hold grudges. Exspecialy when I'm pretty sure the guy knows a hell of alot more than I do about car audio. I was in a pissy mood yesterday anyway.

Sounds good, no hard feelings...and keep in mind, more often then not I'm joking around with people. That's just the way I am. peace

Yea man no hard feelings. Just took it all wrong. Its all cool. I've got a butt load of questions to post so I'm glad you were'nt serious.

And by the way Dice daniels was my sons name. I lost him in a custody battle and then his mother (F'N' bitch) Rolled her car DRUNK and I lost him so no dissin on the name cool. He was 3.

but I'm gonna get off this guys post and start a new one cus I want to know whats up with the amp gain settings this all started about.

well he has a panasonic, not sure what model but its not the stock radio. and as far as the wire goes im pretty sure he cut the right one but the HU is wired totally wrong i think.. not sure though you could be right..

anybody? any other suggestions?

I say that because I hooked up this Pioneer 12" and some ghetto Walmart amp he bought for it and when I went to his HU to hook up the remote wire, it was already hooked up to something. I just cut the one wire, capped it and then used a connector between the pre-existing blue wire coming from the HU and hooked up the new wire going to the amp and everything was fine for us.

And he didn't have a stock HU. He had some expensive JVC or something. Can't remember the brand. Not saying it was good, just a more expensive line the company had.

I thought most headunits have between 2volt and 6 volt preamps i havent heard of to many 7 volt or higher ones.

No I was wrong. If I remember corectly either Kenwood or alpine had offered a hu with 7 volt pre outs at one time. But yea most hu's have 2-6Volt. I dont know where my brain was that day. probably thinking of something else and typing at the same time.
