asd843 Posted September 25, 2010 Report Share Posted September 25, 2010 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. Quote Link to comment Share on other sites More sharing options...

They are decent for a reference line. I've heard 6 PR 12's walled and I, myself, was gonna do 4 PR 15"s walled in my truck. The box tuning is probably playing a role in this more than anything. 650 is good power for two.

asd843 Posted September 25, 2010 Author Report Share Posted September 25, 2010 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. Quote Link to comment Share on other sites More sharing options...
TorK102 Posted September 25, 2010 Report Share Posted September 25, 2010 That may help, but a 900 watt amp shouldn't really need a big 3 and another battery. Have you had the amp bench tested?

asd843 Posted September 25, 2010 Author Report Share Posted September 25, 2010 (edited) 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.

SlimDog53185 Posted September 25, 2010 Report Share Posted September 25, 2010 I built a box for two of those. It was 6 cuft @ 35Hz. We gave them 500w, so 250 each. They moved a lot and got pretty loud. How did you setup the amp? DMM? Quote Link to comment Share on other sites More sharing options...
