JL AUDIO 98277, M500/3: 3 Ch. Class D Full-Range Marine Amplifier, 500 W

SKU JLAM500/3 Categories ,


This compact amplifier is ideal for a simple audiophile grade, subwoofer/satellite system. With the M500/3, you can drive a pair of quality component speaker systems with plenty of clean power, while also delivering a stout 300 W to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design. The M500/3 includes a 12 dB/octave high-pass filter for its main channels, plus a variable slope low-pass filter for its subwoofer channel. Both filters offer continuously variable cutoff frequency selection from 50 to 500 Hz. This marine amplifier features white and gray powder coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
