I'm starting to piece together an aftermarket radio for my 03 sedan, the stock unit and a/c controls have crapped out on me unfortunately.

My question is will an amplified headunit hurt the factory BOSE amp? Do I need to bypass the BOSE amp when installing an amplified aftermarket headunit?

 

it will be like running a line driver to the factory amp, you have 2 options
1. use speaker-level outputs from aftermarket deck, install LOC, balance levels accordingly
2. use RCA outputs from deck, feed directly into amp. (works but not adjustable, probably twice the signal that amp is used to seeing)

so short answer is no.
I should really get my butt in gear and I could sell you my LC6i

 

That's what I needed know. Thanks!

 

I just did an install of 4 6.5 references, 2 eclipse amps and a 2 12's in a box.
THe bose amp is still in there.

The wires are coming out of one side. The guys who did my install did not want to remove it because there are wires hooked up to it. The wires are coming out of the left side of the amp if you are facing the trunk.
What is still hooked up to the amp?
thanks

 

omg wires. better not touch anything.

just kidding. I believe you should be able to disconnect/remove the factory amp. I'm going to do so in a few weeks and go with a 300/4 and 500/1 for speaks and sub respectively. there shouldn't be any reason to keep the stock amp around if you are not using it.

 

thats cool.
Can you let me know how it goes.
I already have my system in so the new amps are hooked up, everything is running, but the old bose amp is in there still, and they were afraid to touch anything becasue there were wires coming out of the amp.
Let me know what you experience.
THANKS!!

 

you can leave the Bose amp in there. Or you can unplug the two wire harnesses plugged into it and remove it.

 

i just recently got new subs and an amp and a new radio/dvd/ipod player and the wiring harness is not compatible with my bose sound system so i was just wondering how to by pass the system to i dont have to run all new wire thx

 

Since you need to run the amp power wire back there anyway, you might as well run the RCA cables from the head unit while you're at it.

 

what is the rcs cable? sorry im kinda new to this stuff so im not really sure

If you buy an amp hookup kit, it usually comes with at least one pair of them.

 

what do they look like??

 

Perhaps if you clicked the link in my reply, you'd see them.

 

i think the easiest way to hook up ur aftermarket head unit to a factory bose system is to use this integration harness where you can adjust the gain to each speaker seperately.

that's what i used and at first the sound was muffled and distorted until i played with the values (i put the screws all 3/4s of the way up) and the sound got exponentially louder and clearer.

 

At this point you should probably not be installing an aftermarket headunit in your G. Have someone else do it.

For the following reasons:

1. Crazy dash kit required
2. An OEM setup with factory amplified speakers is not great to learn on
3. There is a 98% chance that any aftermarket headunit you install will look worse than OEM, and will sound worse than OEM. There's all kinds of built-in level matching and amplification in that factory headunit.
4. 50 bucks isn't that much to keep from goofing up your car. Keep things relative, don't be the guy that puts a $300 body kit on a $30k car, if you know what I mean.

After you've gained some experience in mobile audio and truly understand what you are doing and why you are doing it... THEN go for it!
