Dude this amp is over 10 years old and blows 2 ohm 2000 watt max subs like nothin, took out 2 q power 15s, a fosgate 1100w 12. Weakness? Severely underrated, treat this amp as if it is 2000 w rms, dont hook it up to any sub weighing less than 50lbs. Beast. .

None really. Solid.

Very powerful.

Sometimes slow to turn on in the winter til car warms up

I've had this amp for over seven years and have beat on it. It has performed pretty much flawlessly. I have had it running at 1 ohm since day one and she still pounds. To bad they don't make it anymore. I own a classic.
