Hello everyone....i just have some question...i have aftermarket H/U but i plant to install AMP to my h/u...do i have to unplug the stock amp? please help...cuz i plant to install RCA direct to the aftermarket H/U..and still speaker wires direct in the front (behind the h/u) go all the way to the back for the amp....but i don't know it work or not..so please help..give me so idea...thanks

 

dawg what the hell...that made no sense. from what im picking up it seems you want to install a sub and amp to your aftermarket headunit, right? for that all you would have to do is connect the RCA's from the amp to the RCA's on the headunit.

if your planning on connecting the amp to your door speakers then you need a 4 channel amp and yea just connect each speaker to the amp first and then to the speaker and run the wire to the amp.

if you have a aftermarket headunit then your stock amp and sub wont work

i have no idea if that helps, sorry i didnt really understand the question though
