Blew my Rockville destroyer 15 at low volume
Maximum Output Power: 3000W
I was driving home about a year after her I bought the Rockville amp and sub I was just listening to the system very low volume and all of a sudden I heard a very loud pop and pulled over the subwoofer was blasted up like as far as it could go so I pulled the power fuse and not only did my amp fry but it took out my 15-in Rockville destroyer too so due to defects in the amplifier I lost over $600 worth of equipment and it wasn't even like I was banging it real hard or pushing the sub at all I always baby that system because I paid so much for it and that's what I get I contacted customer support never heard a word back from them. So disappointed in Rockville do not buy their product it works just long enough to get you out of the warranty and then it will let you down all that money right in the trash thanks a lot Rockville ... show more

Good amp
Maximum Output Power: 3000W
The only thing I dont like is that at low volume, it is not as loud as my other amp. But at higher volume, it really pushes some power and makes my subs hit hard
