Stereo wiring diagram
 

I had tried doing a search on the forums and the internet but could not find the stereo wiring diagrams for an 09 Acura TL tech. I just recently bought my car and want a little bit more punch for the low end. Does any have the diagram?

Are you adding aftermarket subs?

Yes I have everything wired except the loc because I don't know what wire to connect to

Or if anyone knows what wire colors I should connect to

I think this is the location:

i found it somewhere. all you have to do is clip on to some of the wires going into your factory sub in the rear. then you get the RCA outputs that would go into your amp. here is a link to the service manual. let me see if i can find the wires you need to connect to. i think i bookmarked it on my home PC:

Ditch the factory amp and wire direct to aftermarket amps. Invest in a DSP and ditch the LOC's. I am selling a 360.3 DSP with about 40 hrs use if interested.

more on the factory wires to go to aftermarket amp.

as zapco said, you gotta have an aftermarket amp for an aftermarket sub.

do you have to unplug and active noise mics to add an aftermarket sub?
