Conclusion: 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.
Conclusion: 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.
Summary: Hooked this thing up configured to a 1-ohm load and wow, runs pretty stable at 300W even when driving for hours. Fits nicely behind my rear seats of the DC tacoma. The sub I have the newer Rockford Fosgate P2D2-10.
Summary: just finished hooking this amp up in my xterra, running a diamond audio d1 4ohm dvc 10 inch sub, wired at 2 ohms, in a ported box, the amp pushes it very hard!! I still can't believe how small this amp is, compared to how powerful it can be!
Conclusion: 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.
Summary: I have a few old JL 12" subwoofers in a box that were only rated at 125 Watt each that I tested this pint size amp on. Although I put this subwoofer package together back in 1995, this amp blew the cob webs off of the dinosaur box and pounded them over 115 db with a nice clean thump with the amp fed a comfy 2 ohn load on these sensitive cones.
