1200 rms watts 2400 watts total power. 600 rms on the 15 and 600 rms on the 12s both at 2 ohm load to a pair of mtx 5601 amps. was just thrown together in my buddy's car for the time being so we would have some bass when we were cruising around town. nothing special just some speakers in a trunk. box for 15 was made by me and was tuned for 25 hz for really deep lows. 12s picked up the high bass.
