alright well this setup is going to be for my lexus but i have a pontiac too so i thought i might as well ask both forums and get input. I would like to run 3 amps. a 4 channel for the door speakers, a 2 channel for a rear deck speaker and a mono for a sub. but the 4 channel amp is too expensive and i already have a 2 channel amp layin around so i figured id just do a 2 channel for front doors, 2 channel for rear doors, 2 channel for rear deck, and mono for the subwoofer. I know how to split up the power wires and the remote wires but i didn't know where all the rca's would go. but im doing more research and i see there is a 8 channel multi line converter and i think that would work. If you have any other ideas i would greatly appreciate the help.
