My HU is Pioneer DEH-P7400HD. Im running two amps. Interior amp is a Pioneer 2 ch GM-A3602 connected to my rear speakers, pair of Polk Audio db521. The front speakers are RF Punch 4x6 which I have running off the headunit. I have a monoblock amp(JBL 600.1) pushing my single Punch 12". The head unit has 3 sets of RCAs (Front, Rear, Sub). My question is how do I connect my interior RCAs? Im sure the monoblock goes to sub, just a bit confused on how to connect the RCAs with the front speakers running off the deck.
