All i can say is that like you, I searched and searched for a decent amp at about $150. This thing is way better than the money I paid. It's amazing!! The sound quality is crisp and clear (tested at 10,000Khz - 22Hz, running 4Ga wire). It never gets hot as I push it around mid-range on all settings. Bass with a single 10" subwoofer is excellent. I have a Scion xB and it really fills the box nicely. I also have it pushing a 6 1/2 component system, which also is awesome-sauce. Trust me people, I looked all over the place for a deal (steal) and THIS IS IT!!!

Does rated power, Using it in a daily driver that does over 148+ on the 2010 TL on music. Vocals sound crisp and clean. Mid bass is smooth and does not distort(you must do all the tuning yourself of course, i left my amps settings flat besides slightly adjusting gain and used my decks cross overs and frequency controls to achieve best sound)

Great amp for the money, doesn't get hot unless you allow allot of bass through to the speakers.

I got this amp 6 months ago, its driving one 10" Kicker CVR, and a pair of components up front. The components are 6.5" Alpine type-x reference speakers. with a Kenwood KDC-x794 as the headunit.

My first impression of the amp, looks good, simple and the price was right. I can't say that its necessarily the amp, but I will say that I expected the system to be a little louder.

That said, the system sounds great...good balance with rich sound. the amp has never gone into protect or anything and has always worked as it should.

They say power is power...so I would be interested to see if a more expensive amp with the same rating sounded louder/better...meaning im curious as to if the amp puts out what they say it does.

All in all im pleased with the purchase
