Is it possible to add a two sub box with its own amp to the Infinity sound system in a 3G or is too difficult to rewire the Infinity?

You are better off buying an aftermarket head unit and plugging your subs and amp into it. Then you get the integration harness and plug that in as well

Okay Thanks :liebe011:

yea but what if i don't want to get rid of my factory head unit since i have the infinity head unit with the 6-dics cd changer? i just want to replace the factory infinity speakers in the front and back with better ones and add a sub system. how hard would that be?

it isn't, but it will sound terrible.

You would have to run high level inputs to the sub, or use rca converters.... which is still a high level input. When you do this, the amp will let by the random high frequency note and blow the sub.

yea but is there some kind of signal processor or a equlizer you could put in the system too. and i was just reading about this thing called the clean sweep that JL has out right now.

Here is a link to look at it:

and it still wont help the sound quality because you have to run speaker level inputs to a subwoofer

alright i just might have to buy a after market head unit. i just didn't want to spend the money of buying one then installing it professionally then have to by a 6-disc cd changer with it i just thought the clean sweeper would be a cheap easy fix. and plus if i get a after market i loose me steering wheel controls and my display up on top too.

Like he said, it's doable, but if you keep your factory headunit and do aftermarket speakers and subs, then it's gonna sound like crap. And if you buy an aftermarket headunit as well losing your steering wheels and controls and up-top display is the price you pay for wanting better sound. There's no way around that man, it's either one way or the other.

yea i finally decided to put aftermarket in i found a head unit at crutchfield

Pioneer DEH-P9800BT:

stinger custom 4gauge wire

brand new infinity kappa's all away around

and maybe just one 10' audiobahn sub or two 12' audiobahn but im not for sure on that part yet but this is all planed out after i get my car fixed just one more week and i should have it done.

If you want a tighter hitting Audiobahn sub I would go with this one.

If you want one that will give you louder but more sloppy/rattle your car apart bass, go with this Audiobahn.

They're both immortal series but they are both amazing subs. They're expensive but it's just a thought.

There is no way he can power those subs. First, they are quad voice coil, second... they are 2000RMS.

In order to do that he will have to upgrade his entire electrical system. His power, ground, alternator, battery or 2, capacitor or 2.... and an amp, good luck. Nothing will power those. You would have to find an amp that runs at .5 ohm... not gonna happen. Or you would need about 6 amps that will run at 8 ohms... also not gonna happen.

He needs to go smaller, especially in this kind of car. The modifications required to build a system with one of those would reach into the upper $4000 dollar range.

Better for his purposes are the eternal series or the flame series.

True, but I just like those subs. But then again they are competition quality so it only makes sense that it's that expensive to power them, cause that's the only people that use them. Or he could go with a cheaper Pioneer Premier, or some Infinity Reference subs as well, and that would be more practical for his application.

well i know this for sure that i am going with audiobahn not matter what. i have a amp already, here are the specs on it:

and i don't know about these dual 4 ohm subs but would this amp work with this sub:

and if so would this one sound good or to much bass and would one do me or do i need to get two.

Um the RMS on that subwoofer is 1100watts. Your amp does 1000watts at 4ohms by 2 channels. you would have to bridge it to get the power to one sub. And with the amp you have there is no way you could power 2 of those things. You would be better off biting the bullet and getting 2 less powerful 10 inch subs and running those off your amp you have. Or if you want that sub you need a better mono channel amp in order to power that thing properly.

He can run the amp to one of the subs and power it perfectly.
-------------HOWEVER----------
Those stats are completely wrong and impossible.

An amp always runs higher power at 2ohm than it does at 4ohm. That thing cannot possibly do 1000 at 4ohm and only 500 at 2ohm.

The real power is 375wRMS at 4ohm and 500rms at 2ohm per channel.

What you will need to do is this:
Wiring Diagram 1 dvc 4ohm at 2ohm

Or:
you can run two of these, which imo are better anyways:
Ultra High power Audiobahn

And you will run them like this:
wiring diagram 2 dvc 2ohm at 2ohm

Yes but it's still a 2 channel amp so it'll be different than the diagram you showed him since the diagram was using a mono sub amp. He would have to bridge it to just run 1 sub wouldn't he?

All you do is use the bridge channel. The diagram is using a mono amp, which is what his is once you bridge it.

The amp will be +-+-... the bridge channel is the outisde plus and outside minus. The diagram is no different.

Gotcha, but he still wouldn't even be able to power even one of those eternal series properly since they have an RMS of 1100watts and the impedance is dual 4ohms. he would be better off with the ones you recommended to him.

Yes he would. Dual 4ohm makes it a 2ohm sub or an 8ohm sub.

So he could power it a 1000rms, and its rms max is 1100
