This is a 4 channel amp that puts out 50x4 @ 4 ohms, 100x4 @2 ohms, and 200x2 @2 ohms. Its in great shape and only a few months old. I have everything except for the little screws that hold the big chrome side pieces on. They made the amp too big to fit under my seat so u pulled them off and put them in the closet. The chrome strips themselves are in great shape. The amp MIGHT have one or 2 small curface scratches but i really couldn't say for sure since its been under my seat. It still works like a champ and there is nothing wrong at all. I was using it to power my components but i have a JL 300/2 in the mail to replace it. I paid 279 on base a few months back and am looking to get 100 OBO plus actual shipping of your choice.
