JL Audio MX500/1 500W RMS Monoblock Wide-Range Class D Marine & Powersports Amplifier (010-03325-00)

The JL Audio MX500/1 provides efficient, compact amplification for demanding marine and powersports installations. Unlike a conventional low-frequency-only monoblock, this wide-range design can be configured for appropriate full-range or subwoofer applications. Its water-resistant chassis and NexD switching topology make it well suited to locations with limited space and potential moisture exposure.
