I have installed a mono amp for my subs, I want to install a four channel amp to power my new door speakers, I noticed there is only 1 RCA output on my head unit, how do I wire the second amp? Any help would be great thanks!
You can get splitters from jaycar or any good stereo shop they are just like a double adaptor for RCA cables.. Ask your local dealer and they will hook u up
Yes if you split them strait out of the head unit it will give both amps sound. U can adjust both to how u like them ...
Depending what amp you have, you can run the secong 4 ch amp off of the speaker level input. That way you keep the fade/balance. Just means you have to run your front speaker wires to the amp and then back again but better than just splitting the single rca.
