It's about 6 inches long and under 2 inches tall, and it fits behind a dash panel, under a seat or inside a door panel.\u003c\/p\u003e\n\u003cp\u003eIt makes 4 x 125 watts RMS at 2 ohms, or bridge it to 2 x 225 watts. That's plenty to bring a set of door speakers and tweeters to life, and the high-pass, full-range and band-pass crossovers let you clean up the bottom end.\u003c\/p\u003e\n\u003cp\u003eEvery C Series amp is checked on Audio Precision test gear before it leaves SoundQubed, and each one carries thermal, overload, DC output, short-circuit and voltage protection.\u003c\/p\u003e\n\u003ch3\u003eC4-500
