Everybody is going to laugh but by FAR my fav piece ever is my kole 2400D. I have never personally seen a amp take the abuse I have put this one through. Had it half ohm. Ran 9 subs. Ran 8 subs off of it. 6 12's off of it. 4 12's. Had it a few years now lol. Had loose fuses causing arcing melted the plastic on the fuses. Dropped it off the trunk of a car on it's side onto concrete. No damage. one day I took the bottom off the amp to look at the guts and there was water damage on the board where at some point It got wet (prob when i had leaking trunk in zx2). Still ticking. Never once has it even went into protect. I love that dang amp. I think a part of me will die when it finally gives off the smoke one day
