[2 Memphis 15's]

I haven't had it tested. I know it works, the subs flex a little but you can't really even see it unless you look close. I've been looking at videos of people with the same subwoofers trying to see what type of amps they have.

Well I don't know the tuning on the box, since I bought it used. I do think it's the amp because I was looking online and everyone runs this amp on like 2 10's. I might do the Big 3, then get a new amp, then after that get a battery for the amp itself and see if that works.

I just got 2 Memphis power reference 15's in a ported box. I was looking at their site and they recommend 250 watts RMS. The amp I have in there is a Arc Audio KAR 900.1D. The box says:

RMS Power Bridged @4 ohms 1x 900 watts

RMS Power @ 2 ohms 1x650

RMS Power @ 4 ohms 1x400

I have it hooked up at 2 ohms and it is barely moving the sub. I had 1 12 before and that was louder. I figure I need a better amp, so any suggestions

And what other things would be smart to do? Batteries, alternator, etc.
