Is there a way to install two amps when the head unit has only 2 RCA (left and right) coming out? I have a 4 channel amp for the doors, and a separate amp for 12" sub box.
Do I just use a splitter on the RCAs and run 4 to the 4 channel amp, and 2 over to the 2 channel sub amp?
Would it be ok to run the speaker wire from the head unit to the high level input on the 4 channel, and use the RCAs for the 2 channel sub amp?
It's been decades since I did this kind of stuff, and back then I didn't even pay attention to what I was doing. As a highschooler I didn't care to think about ohms and RMS vs Peak. But this is going to eventually be my sons Jeep and I want to make sure I get it right and not over work any of the new equipment.
Thank you for any help.
