Hello i'm installing a 4 channel amp for speakers and a mono amp for sub, do i need to run rca's from the head unit to the sub amp or can i just run rca's from my 4 channel amp to the sub amp? what is the difference? Also do i need to run the speaker wires and the rca's on different side of the power wire or is it just the rca's that need to be away from the power cords? thanks

 

If your 4 channel amp has a set of pass through rca outs then yes you can just run rca's from that to the input on your sub amp. Yes it is a good idea to always run rca and speaker wires as far away from any power wires as possible. Hope this helps.

i installed the rca's from my 4 channel to the mono instaed of from the head unit and now i cannot control the sub from the head, so i'm thinking i need to run the rca's from the head to the mona amp, what do you think?

 

thats how it should be done
