With the right system this amp is perfect. Whoever said this amp won't bump is either misinformed or ill educated in sound equipment. I'm running this with a mere 8 inch (e3.8) in a .35 sealed enclosure at half power, and my little Ford Focus looks like its having seizure. If you want a little more, try a 10 or 12 inch MTX with a nice ported box... assuming you are tuned correctly you are gonna bump without trying. Just keeping it simple people. I am tired of wannabe bass enthusiasts and their 1000 watt boss amps (this 250 will push nearly as hard with 10X the quality). Oh, and I should mention... your R250-1 will exceed its rating. Mine pushes a guaranteed 272 watts, just check the certificate when it comes in the mail.

It is a really good amp, like the title says, another great product from Rockford, I saw a couple of reviews made by a soniclectonix guy (not seth) and I decided to buy it, it feels really "well made", nice finish, power led is blue and it will illuminate the hole trunk, rated at 250 rms by Rockford but the birth sheet says the final output is 279 rms (certified by CEA2006) so this is great and delivers true power to your sub. It hits really hard and the knobs let you control crossover, gain and punch are very convenient. Overall, very good amp for beginners in car audio, this amp will not let you down. The only "not that good" thing a can say about it is that is not the cheapest amp around, but I guess that I you want high quality you have to pay extra for it

PD. The shipping weight is about 8 pounds not 6

This amp sucks. It lasted 4 months then blew up. After it fizzled out, it started draining the battery. I had it mounted in the cab of my truck, and had plenty of air flow around it, and it still ran hot.
