I have this hooked up to an RE Audio SRi 10" in a 1.5ft3 probox and this thing slams. You can hear it down the street. Birth sheet said 94 watts at 4ohms, 175 watts at 2ohms, 304 watts at 1ohm, and a max of 911 watts. I recommend getting the PEQ remote because there are no adjustments of the +18db punch eq other than from the optional remote. I can't wait for the release of the PBR300X4 to hook up my highs, just ordered a new set of power RF T1652 to go with my 525s.

I use Rockford Fosgate PBR300X1 for drive sub woofer box. It's very compact with high power. Enough for drive bass power. It's a good choice.

This amplifier has been fantastic. So much clean POWER from such a small package. Easy to mount, easy to hide, it's just a great piece of audio engineering. I would HIGHLY recommend this amplifier to anyone in need of a very solid amp, in a very small package.

I really like this amp alot. I have two of these in my car running two 2011 P3 12s. (One to each sub wired at 1ohm). These slam! I custom built a box to spec for the subs and no-one believes me that they are taking only 300 watts RMS each. People cant believe the power these little guys can push. They sound great and can fit in tight spaces. You would almost have to hear it to believe it, they did SO much better than I had expected. I also paired these with a PEQx3 and are run through a 360.2.
