Boss is the Bomb

This amp kicks much ass.I have it wired to 1 12" Pioneer In a 1.74' box ported and it pushes this 12 bigtime! Great Amp. and for the price, you really cant beat it.

I Love This Amp!!!

I love this amp. It pushes enough power to make my Two Twelves Polk Audio DXi's and my two Apline Type E's also twelves they pound the snow right off of my trunk. Only bad thing is you can only run 4 Gauge wire nothing more, i like the differnt options it allows alot of different fine tuning. I would recomend this for 3-4 Differnt subs or 1-2 High powered subs. Great amp!

Bad egg, big bangs

First one I got died after a couple of weeks, but it was just a bad egg. Got a replacement and it hasn't let me down yet! This thing got so much juice to give out, and the little details such as the wiring setup makes this so easy to deal with. From now on, it's Boss half the way and Pioneer the rest.

Great amp.

I bought this amp for my little brothers car. I bought it to push one of my old mtx 10 inch sub that I gave em. Wow. I think this amp is underrated. It pushed the sub hard. My brothers car is sound proofed very well and it still rolled the mirror down when it was barely turned up. I would recommend this amp to everyone. Especially if your trying to save money and get a great product. Thanks sonic. Ps my brother love the remote sub control.

Very Nice power, quality, and options for price

No RMS rating is available by maybe it's around 800-1000W RMS at 2 Ohm and maybe 600-700W at 4 Ohms with 14V. Runs fairly cool at 4 ohm but can be a bit hot at 2 ohms if you really max it. Definitely nice amp for the RMS power you get. Would I buy it again? It depends... If running at 8 or 4 Ohms, Yes. If running at 2 Ohms, definitely yes if I'm trying to power a 600W RMS subs. For 800W, maybe get the NX4500.
