I have a alpine mp3 deck with 2 rca pre outs and i have two kenwood 600 watt 2 channel amps with 2 rockford fosgate 15inch subs how can i hook it all up?
Uhh... hook the amps to the deck, hook the subs to the amps and then hook the amps to the battery. Done.
In other words, try to do some research before you ask a very broad question like that. And before we could even begin to give you advice, we would need more info than that.
