Ijust put a P3D4-12 in and was debating between this and the R1200. Let me say if you're on a budget, this tiny little guy is a beast!!! Its birth cert. Says 648rms and it is rocking my p3. All knobs are in easy to reach places, I have nothing bad to say about this amp. Will only recommend RF to others
Great little amp. I'm using mine to push two 10" JL Audio Subwoofers. Been using it for almost two years now, no problems at all. More then enough power, in fact I've got so much power to spare. Have to turn the gain almost all the way down to 1/4 of the max. Great clean thumping sound that compliments my factory Bose stereo system in my Chevy Silverado. Would DEFINITELY purchase again.
Best bang for your buck.
Good things come in small packages is an understatement for this amp. I have had this amp for 2 years and it is very reliable. I went on many road trips and bump the whole way. After 5 hours the amp is never even gets hot. I recommend this amp to everyone.
Best amp for the $
I bought 2 of them thinking I would need both. Boy was I wrong! I have pushed 2 12s, a few single dual voice coil big boys, and it has always done great. I sold the other one to a younger boy and we put it on his 2 12in fosgate p3s. Perfect match .Love it. Keep up the good work. P.S.-I need a remote for mine.
Just got mine yesterday, I paired it with an Audison 10" Sub. After the install, the technician said it was pushing 650 RMS! It sounds amazing, great product.
