JL Audio XD400/4V2 4-Channel Car Amplifier

Overview

Power your system
JL Audio's XD400/4v2 amp packs a wallop far beyond what you'd expect from something so small. This compact amp plays your music with true fidelity and impressive impact, without straining your car's electrical system, thanks to JL Audio's proprietary NexD amplifier technology. 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.

Versatile amp
The XD400/4v2 can deliver 75 watts RMS each to 4 full-range speakers, or you can bridge the amp to 2-channel mode to send 200 watts each to a pair of subs. You can also run two speakers with the front channels while driving a subwoofer with 200 watts RMS from the rear channels bridged together.

Works with almost any vehicle's system
"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. The speaker-level inputs feature two auto turn-on modes so you can readily incorporate this amp into a factory system no need for RCA connections or a remote turn-on lead. An optional wired remote lets you tweak the volume of the whole system from your front seat, or you can switch to the rear channels only, which is handy if you're using them to drive a sub.
