    I bought it thinking it was brand new. Box look like it was never open but little crinkle damage here and there. Open up the box and come to find out it was a used amp. It has burned mark on the terminal ends, where you can tell two wires touch together made a spark mark. I continued to hook it up, it seems to work ok, but every once in a while sounds like my bass it dropping out. Not sure if I can return it with the previous spark marks that I didn’t make.

    I wish there were numerical labels on the settings so you could see exactly what you have your crossover and everything set to, but it works. The automatic turn-on is a nice feature, as is the output for chaining amps together.

    This is a great amp. I have this running 2 8” Subs and sounds great. It’s fairly small in size so makes it easier to find a place for it. I bought that as an open box deal so that made the price even better. No complaints here

    It is a decent piece of equipment. Unfortunately I paid way to much money for decent. I feel I could have gotten an equal value at a much lower price. It does work good though.

    Bought this amp might have been drop or used then resold as open box and after 2 months the amp stopped working turning itself into safe mode. Took it to get it check and it’s literary not good no more. Don’t buy anything open box because (no warranty) I though I got a good deal and got the end of the stick on it.
