JL Audio 5-channel car amplifier — 75 watts x 4 at 4 ohms + 600 watts RMS x 1 at 2 ohms

XD1000/5v2 connection and control panels JL Audio's XD1000/5v2 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. 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. This 5-channel amp can power your vehicle's entire system, delivering 75 watts RMS to each of your front and rear speakers, while powering a sub with up to 600 watts. You can also switch to 3-channel mode, and power a pair of high-performance speakers with 200 watts each, while still driving a sub with 600 watts. High- and low-pass filters give you intimate control over the character of your sound. "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 output...
