Customer Reviews

mitch From wisconsin
I was very impressed with this amp. I have this amp powering two 12" MTX 7000 series subs. I was so supprised by the quality and sound output from this little amp. It never gets hot, has never once over-heated, and its sitting in direct sunlight in the back of my trans am. My amp was rated at 390 watts.. when the factory specs are 311 watts. Awesome!
