To be realistic, no matter what you're wiring at you're probably not going to see the amps rated power anyway. After voltage drop (depending on your electrical) and impedence rise it might get you rated (doubtful) get more than what you need. that way when you wire to 1 ohm and you rise to 2's and your'e getting like 7xx out of 1 amp you're not looking to upgrage and back to square 1
