Still on the Fence

Ease of Use
So I'm kind of on the fence with this amp. I went with it based on a recommendation from an advisor here. I specifically went with this amp because it's rated at 800 watts at 1 ohm. I have 2 DVC 12" Kicker that I specifically wanted to wire in parallel for 1 ohm operation. The first thing that I think is a little weird is that the amp is actually rated lower at 1 ohm than 2 ohms. Probably just an engineering method to limit heat produced. I've set the gains a couple of different ways. 1. by digital multimeter using ohm's law. 2. Then I got a distortion detector that allows you to set gains at the 1% distortion level. The problem that I'm having is that during big bass kicks, it goes into a temporary "protect" mode that basically cuts power to the sub. This, I assume, is a good thing. The only problem that I see is that I did a "clamp" test on this with a 50 hz test tone and it shows I'm only getting about 435 watts. My deck has no distortion at full volume so I set the gains using full volume on my kenwood 6702s deck. Granted, it sounds great and runs cool but a clamp test is normally pretty generous so in all likelihood I'm getting less than 435 watts at 1% distortion. I'm going to reset the gains and run some more tests but I'm kind of disappointed. I just expected more "clean" power. At this point I'm kind of disappointed I just didn't go with a set up that would allow me to run at 2 ohms instead of 1. We will see. This one may be going back.
Pros: Sound quality, Runs cool. Looks Cool. Unit has a variety of measures that will prevent it from over heating.
Cons: Don't seem to be getting rated power. Description and Alpine Website states that you don't need a remote turn on wire but the manual never mentions not using a remote turn on wire.
