Ok, well I actually have 8g wiring coming from my battery (only two memphis 10's with a 600w crossfire amp), so I have a distribution block with 4g in and dual 8g out. I got it for free so I was wondering if that will work if I just put the 8g in the 4g spot. I dont see why it wouldnt work. ALSO, where should I have the Rem go on the little amp????!!!! Can i just split the Rem wire going to the big amp and just add wiring in to the little amp or how should I go about connecting that all up??? Reminder there is no more spaces in the back of my deck to plug anything into. And is RCA the same thing as Rem???
