Can someone please help me. My amp has two sets of left and right channel inputs (a total a 4, two reds and two whites). likewise my deck has two sets of preamplifier outputs. The deck has them labeled preamp front and preamp rear. Also my amp has a high input to connect the high level inputs. This is confusing. How do you hook all this up. do i hook up all 4 outputs coming from the deck to the amp and what about the high level inputs at the amp. Please HELP ME WTF!!!!
