I purchased this amp about 6 months ago, and took another 2 months to get everything installed. When i finally got this amp hooked up, it pounded the crap out of my subs, PA as well. It lasted for about 2 months, then just stopped working. I thought it might have been the subs that blew, but i hooked them up to my other amp, same model, and they still worked. I unhooked it, and reinstalled it again, still nothing. It sounded great while it lasted, but now that it doesn't work, it is just a fancy looking paperweight. Be careful with this item.
