Wiring in amp to bose system...

[Steve19Ohio]

Ok here is what I have installed in my 01 Audi TT Coupe

Audi Concert Model: 8N0 035 186 A

Bose Sound System Model: 3511

Both came with the car from the factory. I wan to add a 12” sub in the trunk but I would like to keep the stuff I have in there already. The only issue is that the speaker wires coming from the head unit use a common ground wire. So how to I wire in my amp? Do I just connect both ground wires to this one? Any help would be great. Thanks…

Oh the AMP I want to install in addition to what I have is a Kenwood KAC-5204. Thanks again….

Hear is the pinout for the headunit

what do you mean when you say both grounds.

and im assuming your talking about running the amp off the speaker lvl inputs

Yes sorry not to clarify that. The amp has speaker lvl inputs I would like to use. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

and again, what do you mean by both grounds?

The amp I want to install is a 2 channel amp. So it has Left and Right both with separate grounds. However the head unit has only one ground for all speakers. Sorry for not being clear. I don't know much about car audio.

hey i just installed a 15 inch in my a4 and i used a Line out converter or a speaker level input (my amp had it) i got the signal from the rear speaker tapped into it. then i ran the remote wire to the factory amp that was in the back with the 6 disk. then ran the power to the battery like normal. everything works as of now. im not sure if its the best way to do it but it works for what i want. you might want to do some more research but i hope this helped thanks.

Thanks for the info. but I'm sorry to say I have no rear speakers. I have woofers that come out of the amp in the back. The thing is I can't splice into them because I read that Bose has a Mic in my car to automatically adjust the bass so I can't blow my speakers. So if I were to tap into that my amp would be controlled by the Bose amp... //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Do you think you could point me in the right direction? I've looked online and I can't find an adapter I could use. That or I'm not sure what the right type of adapter to use. Thanks again.
