I never thought about the rear speakers, reason i wanted to tap behind the headunit because i heard its not a pure signal, the amp already had its way with it, if that makes sense. My friend wants to keep his stock radio because he does not want to attract attention, usually when people see a face off, they think system, and thats when they break into a car lol.
So yeah, we got all the stuff, i am doing the install on Sunday morning.
It will be a lot easier
