I'm using this amp on a JL Audio 10W0v3-4 in a Single 10" Sealed MDF Enclosure (10SQTC) and it thumps. My jeep has never sounded so awesome! I have to admit I was nervous ordering such a cheap amp, but this thing is delivering. One issue I did have early on was the set screws used to clamp the speaker wire in place.... they are Phillips head and way too shallow to actually tighten the set screw properly without stripping them (I know because I did). I just went to the hardware shop and picked up some 8-32 machine screws and they do the job great. This amp looks nice, the logos light up and are cool at night, just hope they don't get me pulled over.

I was asked to get an Amp for a friend's Birthday. I had already bought the f-4 series 12" by FLI (which is one bangin' crazy thing) so.. after getting the Amp, hooked it to two older JL Audio basics. Amp looks great, detail in the cover plate for controls is nice and sleek, screws didn't want to cooperate during mounting, so I used my own. The claim of 225 watts is dead-on! With correct tuning on the deck unit, and having an enclosure that is right, I would be willing to say, at the price You could scare people with the volume. Nice little Amp.

Have her bridged to a 12" Kicker Comp C124 in a sealed enclosure and the sound is clean and tight. The Comp is rated at 300 watts peak and 150 RMS. The FLI is 450 watts max and bridged 4 ohms puts out 225 RMS. Great match and nothing the gain level can't solve. This could push a single 250 RMS sub with no problem.
