I bought this amp in October of 2012 to power my first sound system, a 12 inch Kicker Comp (4 ohm) in a ported box. Although this basic sub is only rated at 150 watts rms I figured I could safely push 200 watts to it since Kicker is known to underate their products. And for almost 6 months, it has worked flawlessly, the amplifier barely even gets warm. The blue LED light strips glow really bright when its powered up and they make the trunk look cool at night. The only thing that I find strange that no one else has pointed out is this: I'm pretty sure this amp puts out way more than the 200-300 watts rms thats listed. The fuse rating on it for example, is 60 amps! This was something that my friend who works at car audio shop pointed out to me. Most 200 watt amps have 25 or 30 amp fuses...a 60 amp rating is usually only necessary and used on bigger 500 or 600 watt amps. It certainly seems true, because I only have the gain turned up not even half way and it maxes out my 12 in. Comp and thats at 4 ohms. I'm thinking of upgrading to a Kicker CVR in a bit, and at least I won't have to upgrade my amp, because I know this thing will push it no problem. Bottom line: This is a tough, powerful, reliable, and really cool looking amp for a pretty damn good price. Just be aware that it is a bit more powerful than the ratings suggest, so if you're using a weak sub, make sure you turn the gain down so you don't blow it. :)

I bought this amp a couple years ago and its on of the best built amps. Great quality and built like a tank. I abused the hell outta it and ran 2 12's till it got too hot to touch. Even when I blew one of the capacitors inside it still never quit and its powering my rockford sub in my car with no problem
