Good day all, i am pretty familiar with installing systems, it used to be my hobby. But now things are a bit more advanced. The stereo I have is a BOSS BV7320. It has two sets of RCA jacks (front left and right and back left and right) and it also has a subwoofer single RCA jack. I also have an equalizer (pre-amp) that i want to use (to get that cleaner sound). The equalizer thou, only has one set of audio input RCA jacks, and one set of out RCA jacks. one of the amps that I am running for the highs is a four channel, (front and rear) inputs. and the amp that will be pushing the bass is a two channel which I was going to Bridge. How do i connect all this?
