A kilowatt for your sub
JL Audio's XD1000/1v2 amp packs a wallop far beyond what you'd expect from something so small. This amp plays bass with true fidelity and impressive impact, without straining your car's electrical system. A cast alloy heatsink and an advanced cooling system keep this amp at optimal temperature, eliminating thermal shut-downs so your music keeps going strong without interruption.

The XD1000/1v2 mono amp delivers up to 1000 watts RMS to your subwoofer system, and its low-pass filter features a choice of slopes for better control over the character of your bass. A subsonic filter allows you to tighten up your system's kick and gets rid of any inaudible, low-frequency information that could detract from your sub's performance.
 
"Differential-balanced" inputs keep the signals clear of outside noise, and allow you to connect this amp to just about any in-dash stereo, even a factory radio with no preamp outputs. An optional wired remote lets you tweak your bass level from your front seat.
