JL Audio 3 Ch. Class D Full-Range Marine Amplifier, 500 W - M500/3
| $849.95 |
3-Channel Class D Marine System Amplifier, 75 W x 2 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V
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 50-500 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.
