Very nice little amplifier. I am very pleased with the deal I got too.
I saved a fair bit of money buying a 'used' amplifier here on Amazon. Other than a few scuffs and no original packaging it doesn't look like it had ever been installed. I am using it in bridged mono mode, and installation was very straightforward, and it fits nicely behind the driver's seat of my very small sports car. It won't blow the windows out, but that doesn't interest me in the least. It adds nicely to the bottom end, and controls my 8 inch Alpine subwoofer with little effort.

Great amp, with awesome sound and definite value for the money
Sounds really better than expected. Looks great and inconspicuous. I have mine wired at 2ohms. It holds stable with no drain and no overheating. Easy to connect and the auto on/off feature is great. You'll really enjoy this amp. It provides a great sound over stock any day. And if we're being honest, i actually bought 2!
