I want to run an older Alpine 3523 2 channel amp for my subs but need help with the hook up. My questions would be; 1. Can I go RCA sub/pre out from my Alpine head unit and into the RCA in's on the 3523 and bypass the older style (molex?) input? 2. Can I "jump" a "remote on" wire from my new Alpine 4 channel amp which runs four 5 1/4" full range speakers? 3. How would I bridge the 3523 to run two Kicker 6x9 mid bass in a custom sub cabinet. I see a variable/fixed switch and a stereo/mono. Thanks in advance, Mike.
