[QUOTE="fly_marlin, post: 8386872, member: 660781"] You can do either way, I think another 4awg is easier - you don't have to take out the other power wire. You have 3 sets of pre-outs on your deck. One of them is for the sub. You'll need to run a 2ch RCA cable from the sub-out to your sub amp. Then you'll need 4ch RCA cable from the remaining outputs in the deck to the inputs on your 4 channel amp. You will not be using the RCA outputs in this case, so don't plug anything in there. Your terminology is a bit off. You won't be bridging anything. The amp, as most 4ch amps do, has separate adjustments for front and rear channels. I don't user rear speakers, so I have less to adjust. You will set the amp for 4ch operation via the switch. The x-over you will set to HPF for all channels. You will then set the HPF dial for all channels to about 120Hz, you don't need to touch the HPF. This means all your speakers will essentially play frequencies above 120Hz. You can do small adjustments to the HPF dial based on your taste - listen to some songs you're familiar with and see what sounds best to you. On your sub amp, as you may already have done, you will only use the LPF and that's generally set around 80Hz - again adjust that slightly from that based on your taste. Your deck may have crossovers in it that you can utilize. If you do use that, set the x-over setting to "full" since you don't want to be crossing things twice. You'll also need to run a second remote wire for the new amp. Are you about to pull the trigger on that amp? [/QUOTE]
