Speaker wire to RCA cable to amp
Hi there new here, I recently got a 4 channel amp to go along with my car system since my mb quarts are being a little underpowered and un crossovered by the head unit. I have a bit of a situaion though. On the head unit its all speaker wires and 2 rca cable outputs for the sub. I already have the sub output filled so my question is can I take the powered speaker wire going to the speakers cut them and splice into a RCA cable and hook them up to the amp in order to make this setup work? If you can help me out that be great thanks!
