I have a mach radio in my 02 gt(not the 460). I have already put in a aftermarket head unit. I have a four channel amp that I want to use to run the four front speakers. Is there a essay way to tap in to the stock front speaker wiring or do I have to run new speaker wire to the aftermarket amp??

 

I've been known to cheat and sometimes use the harness at the back of the aftermarket radio and run my amplifier wires from there, instead of connecting to the aftermarket HU's amplifier.

Another place I've been known to tap into is the bundle just before it enters the kick/door. I find the wires going to the factory speakers then tap there.

The true SQ, car audio guys tell me that I am hurting my performance by NOT running 14 or 16 guage speaker cable directly to the speakers. My retort is to always ask them if there is any way I will hear a difference traveling 70 MPH down the highway.

 

I was going to try to tap in to the wires were they plug in to the stock amp, but Idk how hard that's going to be lol. But that's a good idea to look by the kicker panel.
