The S120.5A is a complete powerhouse with a built-in monoblock amplifier to run the enclosed high-power 12-inch subwoofer, plus an additional 1600 watt 4-channel full range amp with high pass crossovers to power the rest of the speakers in your vehicle.

General Features
Just installed in my girlfriends 2000 Mercury Mountaineer. Using it to run 4 Kenwood 6x8's sounds great. Highs and mids are fairly good and lows are surprisingly good. Install was a breeze, though i would have to say the Continuous Power rating is way off. I'd estimate about 35watts x4 RMS and the sub is about 150-225 watts. This is perfect for someone who wants to bump, but doesn't want to be heard outside of their own vehicle. We just got it for those long trips we have 2 tv's and now the backseat feels like the movie theater. Overall great buy for the money, not for bass-heads but it did make my rear view and side view mirrors shake. If your looking for bass try a rockford fosgate 400.1 amp paired with Polk Audio db212-2 subs, great setup.
