supreb product

I purchased this item to bring the sound out on my 04 chevy Silverado, and I must say I was very pleased of the sound I got out of it. I will recommend this product to anyone.

Underrated, Overrated Amp

Crunch "Maxxsonics" always overrates their amps, and most people scoff at the brand, but if you ask me, its an underrated brand and always has been since the 90's.

One of the major criticisms is the noise ratio, however, when tuned these amps are crystal clear with plenty of backbone with zero distortion.

The only complaint I have with this edition is the fact the manual is so far off, and not to mention regarding wiring and features, the "Bridgeable" range printed on the actual amp is also wrong. To bridge a sub, you'll need to run positive off of channel 2 positive and negative off channel 1.

I don't have much headroom off this amp, if I had space, I would have run the next model up, but its getting the job done, without any overheating problems; its cool to the touch suspended vertically from two wooden dowels.
