JL Audio 500/1v2

The JL Audio 500/1v2 is a class D monoblock subwoofer amplifier based on a high-damping class D circuit with discrete control circuitry. The first model in the Slash v2 to offer only one channel, the Audio 500/1v2 supports up to 500w rated power, a 5Hz-250Hz frequency response, and a >500 @ 4 ohm dampening factor.

Like its cousin, the Audio 250/1v2, the 500/1v2 also includes 2-channel preamp output, a fully-variable 24dB/octave infrasonic filter, and a signal-sensing turn-on capability that permits operation without a remote lead. In addition, the Audio 500/1v2 is priced at $599.99, a $100 less than its one-channel competitor in the HD series, the 750w HD750/1. The JL Audio 500/1v2 is considered an ample choice for consumers seeking a powerful subwoofer amplifier that is powerful, yet also affordable (at least in regards to other amplifiers).
