JBL CLUB A5055 5-Channel 50W x 4 @ 4-Ohms + 500W x 1 @ 2-Ohms Car Amplifier

The Club A5055 5-channel amplifier delivers a powerful 50-Watts RMS to each of the front and rear speakers in your car, and a pounding 500-Watts RMS to the subwoofer channel — a much smarter ratio of subwoofer-to-full-range power than what is typical in 5-channel amps. You can also bridge the amp to 3-channel mode to deliver 140-Watts RMS to your front speakers while driving your sub with 500-Watts RMS. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your car's factory radio. Separate high-pass and low-pass crossovers on the front and rear channels allow you to dial in the perfect roll-off to best suit speaker placement and cabin acoustics. The subwoofer channel features a low-pass crossover, selectable bass boost, and phase switch to optimize subwoofer performance.
