Great Amp!

Great Amp! I bought this for its compact size, price and wattage. I mounted this under the fairing of my Victory Cross Country motorcycle. I have used Rockford Fosgate in the past and I'm happy with their products. You will be pleased with this one! Thanks Sonix for the fast shipping!

Excellent Value

As per usual, Rockford Fosgate comes through again with another great product. I got this to power a single Punch 8" woofer, and it does a great job with that sub. The amp actually tests at 140w (bridged) instead of 125, which is a pleasant surprise. Fantastic value for the money in a small amp. Great customer service from SonicElectronix as well.
