Report "I have a volfenhag zx 7160 car amplifier and would like to know proper wireing for speakers? The amplifier is capable of 2,3,or 4 channels. I have a 15" rockford fosgate subwoofer and two 3-way speakers. The amplifier combines the 1&2 channels and the 3&4 channels so that they can be bridged independently. Can I bridge 1&2 channels for subwoofer and run my other two speakers off 3&4 channel? Also what would I need to set it to for all three speakers? The amp has two separate function buttons for xover mode (LPF,FULL HPF). Can I use the 1&2 channels for LPF for subwoofer and 3&4 channels for full range?"
