Lots of Power in a Small Package
Small form factor, excellent sound and especially well matched to Polk speakers. This actually can fit behind the dash or under a front seat, and it runs cooler than non digital amplifier designs. And the price was very reasonable as well.Read full review

Great quality amp
A lot of clean power in a small amp. Have it pushing my front components using the crossovers for an active setup, sounds great. Really like the bandpass option and frequency multiplier option.
