I am a noob. I have a budget system consisting of a Sony Xplod 1252GTR powering a 10" Visonik sub. The amp is connected to a JVC KD-G320. I want to add another 1252GTR amp and another 10" sub. Is it possible to take the RCA cable and send the left side to one amp and the right to the other, and the hook a sub to each amp by attaching the wire to the left positive/negative on one amp and on the other have set to the positive/negative right side? I am a noob and it is a budget system, any help would be muchly appriciated.
