Description
Refurbished JL Audio M500/3
This amplifier has been factory refurbished by JL Audio and comes with a 90-Day Warranty.
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.
