Hello, I have a subwoofer in my car with a amplifier wired to my head unit with 2 rca cables (L+R). I made the decision to put a amp on my normal door and dash speakers as well. Will it work if I put a rca y splitter on my headunit to wire my 2nd amp. I have it wired to my subwoofer amp on the line out but it's not making any sound.
