I just got a new car, there was a 4 channel amp running the speakers but I want to put another amp and a pair of subs in my car too, how can I make it so I wire the new amp to the car? or is it possible? i thought about running a power cable from the battery, and then running the in/out cable to the 4 channel from the 2 channel, and splitting the remote cable...does that make sense? and is it possible?
i have a 240 watt and a 625 amp sub that i need to join together to push my 2 12" jl subs. how can i do that? so that i can get all 865 watts to go to the subs.
