The JBL® MS-A1004 is a flexible, four-channel digital car audio amplifier. 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. Channel pairs are bridgeable with fully configurable input-signal steering. Rated power output is 4 x 100 watts RMS into 4 or 2 ohms (2 x 200 watts RMS bridged). Onboard pass-through outputs allow easy connection to additional amplifiers. This amplifier easily connects to line-level inputs or (with included RCA-to-bare-wire adapters) to speaker-level inputs, making it an easy upgrade for a system amplifier in any car.
