Automotive Mono Amplifiers

XDM-Series Monoblock Class-D Marine-Grade Amplifier, 300-Watts @ 2-Ohm or 200-Watts @ 4-Ohm This little monoblock powerhouse employs JL-Audio's high-speed NexD switching design to achieve unprecedented efficiency and amazing power output for its size. It is small enough to fit in most tight space applications, including small boats, pickups, motorcycles and UTV’s (in a weather-tight compartment). Designed for car or boat installations, the XDM300/1 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades. Targeted specifically for subwoofer applications, the XDM300/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain’s chair. Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.

Kicker KEY-Series Mono Amplifier with Automatic EQ/DSP Processor, 300-Watts @ 2-Ohm Kicker KEY series amplifiers use a powerful internal computer to deliver dramatic improvements in realism and soundstage. A massive 40-band equalizer improves tonality, and a 24dB crossover re-defines the capabilities of each speaker. The KEY500.1 delivers 300 watts RMS of power to your speakers at 2-ohms. Measuring less than eight inches long and only two inches high, the KEY500.1 fits nearly anywhere. Mount it behind your radio, under the seat, or in your trunk with ease.  If the temperature reaches the threshold, the Kicker KEY500.1's dynamic power-management algorithms kick into gear! Instead of hearing the amplifier's volume “pumping” or blowing a fuse – KEY technology engages a nearly inaudible limiter/compressor, applied only to the peaks of the music for as little as milliseconds at a time. The amplifier quickly cools, which deactivates the compressor. Music returns to its full dynamic range without a moment’s interruption!
