this might sound dumb but im not sure how you hook up 2 amps to 1 car or jsut the battery itself does anyhting need to be done or can u just overlap teh amp wires to teh battery???
Actually, use a bigger wire like 2 gauge power wire into a distribution block and run 2 ends of 4 gauge to your amp. same thing with the grounds, wouldn't hurt to have 2 seperate grounds though.
