About this product

The JBL® MS-A5001 is a Class D mono subwoofer amplifier that packs quite a punch. Its DSP-based digital input mixer offers programmable active crossovers that include slope, bandwidth and precise filter points. The input mixer also controls accurate output levels. Rated power output is 1 x 500 watts RMS into 4 or 2 ohms. Onboard pass-through outputs allow simple connection to additional amplifiers via line-level inputs or (with included RCA-to-bare-wire adapters) to speaker-level inputs, making it easy to add a subwoofer with substantial power in any car.
