[QUOTE="HardofWhoring, post: 8859598, member: 674149"] I see on Amazon, it's @13.8v 60w x 4 @ 4ohm RMS. If you set gain AC voltage to 14.1v that's 50w per channel. 60w per channel is 15.5v AC. If all you want is 50w RMS, can't you just do that off the head unit? If that's me I'm not going to waste the amp, I'm either getting 4 speakers for channels and speakers that are 50-60w per channel RMS, or I'm bridging and getting a set of components or two ways that are 150-200w RMS per channel. If you bridge it, it's at 4 ohms 2 ch. If you don't its 4ohms @ 4ch. So you will set the gain to the same voltage if you want the same wattage. The difference is [B]if you run it at 4 ch[/B] with two speakers, you are still sending out the voltage for all four. Which means your amp will still draw from your electrical for all four (60w x 2 vs 60w x 4). If you bridge it so that it's two channels, you set the same voltage but you're only drawing for 2 ch, (half the power) is being drawn. It's not much, it's the difference in about 10-12 amps. No clue if that makes a difference on a Can Am. Just to be clear, it's the same voltage going out to the speakers, but wiring it up is twice as much of a draw on the electrical (for the same wattage). If you haven't bought the speakers yet, I would see if I can fit two more. If not, I'm getting ones that could be louder, (especially on an open air vehicle like a Can Am). [/QUOTE]
