Summary: This is a perfect addition to my system. It completes my other amp, which is a P1000-1. Its gonna run my ROCKFORD FOSGATE T1652-S 6.5" 2 way COMPONENT spkrs. If you are looking for TRUE power with EXCEPTIONAL quality, LOOK NO FURTHER!
Summary: This amp is very powerful. Way too powerful for the 2 brand new 10" subs (400watt-150rms) each. Blew them out in a week. This is a serious amp for the serious installer. I have one 12" sub 1000 watt now and it sounds great and I have the gain on 3. Excellent amp and the price is great.
Summary: Awesome item!!!!!!!!!!!Pure and undescribable. This amp is absolutely raw punch power...The thump it pushes to the subs. is incredible. I recomend this item to anybody who is an enthusiast of raw punch power.
Very good and you actually get more than you are paying for. True Power!

Summary: Been buying Fosgate amps since the 80's and they still do not let you down. Got one refurbished on eBay from authorized seller. Hooked it in and measured with a scope and vohm. At full tilt clipped signal put out over 1500 watts mono into 4 ohm. This would be the number you'd compare to those lower level no name brand amps. Real world power you say.... unclipped signal at 13.8 volts put out 973.44 watts 4 ohm mono zero bit 50 hz signal. Not bad for a 500 watt amp!
All Around Great Amp,I Love Rockford, this type of amp is why.

Summary: This amp is Pure Rockford Fosgate. I like that it is a 2 channel and Not a mono block. The terminals are decent to use. The power is clean and even. The wattage ratings are actual with clean sound output. I bought my unit used and despite some cosmetic flaws, It's a Beast ! I highly recommend this amp if you have 2 Dual voice coil 4 ohm subs or a single, dual voice coil 2 ohm sub solo, as this amp is nominal at 4 ohms bridged. I love how small and heavy it is..
Summary: If your reading the reviews wondering if you should buy this amp I'd say yea I replaced a more powerful crunch amp with this one and now my subs get a way cleaner bass with no problems. Cant wait to pick up the P400.4 for my mids and highs. These amps are pretty small but do have some weight and look sweet.
Summary: Very strong amp works well running mids and highs exhibiting very clean and powerful sound. Also works well running subs. When used with a bass control knob this amp can produce powerful deep bass from your subs. The only con I dont like is you have to be careful with the speaker terminal screws as they strip very easily.
