At 14.4 volts, it puts out 4 x 450 watts RMS at 2 ohms and 4 x 300 watts at 4 ohms, or you can bridge it for 2 x 900 watts at 4 ohms.\u003cbr\u003e\u003cbr\u003e\nThat gives you plenty of options. Run mids and highs, power an active front stage, or bridge it for subs or high output mid bass. Both the low pass and high pass crossovers adjust from 50 Hz to 5 kHz with a 12 dB per octave slope, so you can dial in each set of speakers right at the amp. High level inputs also let you hook it up to a factory radio without a separate line output converter.\u003cbr\u003e\u003cbr\u003e\nThe built in RGB LED lighting has sound activated patterns, or you can turn it off completely for a stealth install.\u003cbr\u003e\u003cbr\u003e\nFor full rated power, plan on upgrading your electrical system.
