good amp for price

good overall amp for the price no overheat problems hits hard sounds good

I would recommend....

I got this amp not really knowing exactly how it would perform but as soon as i got it home and hooked it up i was amazed. Even though its not an incredibly powerful amp it works great for cars. You can actually tell a difference when adjusting the frequency and bass boost. I would recommend this to anyone who doesn't want so much bass from a sub to wear you cant breath but to people who like a nice and crisp sound from an amp but still will be able to crank it up if they want too.

great amp

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

Great Sub for the Price

This is a quality amp, and at this price it's hard to beat. I push my subs pretty hard, and after 8 months, I've had no issues.

thump, thump

I got this amp to replace a smaller in size but higher in power. I've taken a lengthy road trip with this amp and had no problems. There were no over-heating issues and I also love the few adjustment dials instead of the many others have. This amp is the one I was looking for to start with. You will not be disappointed.

Great Value

I got this amp in a combo special and it performed awesome until it had a fault. But Infinity is such an awesome company they replaced it for free. Great price for a good amp from a very respectable company.

Running dual ohm with a 12" pioneer champion series. Only overheated once on a pretty intense bass line. Solid..cant go wrong with it other than that,.

Reliable Power and Good Looks!

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. :)
