In the last few years I've owned about 4 different Boss amps and have NEVER had any problems with them Including this one. Whether or not Boss overrates their products remains to be seen. People who say they do, most likely have heard that from someone else who heard it from someone else who heard it from one of those people we like to call "know it all's". Not once have I read about someone actually putting it to the test themselves. Anyways, I bought this amp about a month ago and over all, I'm pretty happy with it. I currently have it pushing two 12" pioneer premier's (ts-w2000spl). I've had it running at 4 ohms and it was doing just fine and pushing my subs pretty hard; verified by multiple complaints from my wonderful neighbors. Yesterday, I wired my subs down to one ohm just because I wanted to see how much power I could squeeze out of this amp. I'm not sure yet if I'm going to leave it that way but we'll see. Needless to say, I almost blew my subs. It did get a little warm so I've decided to get a fan or two for it just to play it safe. All in all I WOULD definitely recommend this amp to anyone! The one and only complaint I have is that the level, the subsonic filter, bass boost etc.. are located at the bottom of the amp instead of on the sides, which in my case with the way I have it mounted, makes it hard to adjust any settings if need be. I did a lot of research and probably looked at just about every other high power amp out there for this price and I'm pretty confident that this amp is going to be the biggest bang you'll get for the money. If you're on a budget and are looking for something with a good balance between being cheap & reliable, go for it but by all means if you got the chetta get something betta!

This amp has a great price but I have noticed in the 6 months that I have had this as usual BOSS once again overrated this amp. 2100 RMS you say? It hits less hard than a 900 RMS kicker. It's decent but you can get better. Doesn't over heat and lasts.
I wouldn't recomend it since it is overrated. Spend the bit extra and get a quality amp.

I was hesitant to purchase this product due to the same reason as the prior review. Boss tends to overate their wattage and that's what they did. This is pushing out less than my friends 1500 Kicker amp. Looks decent and doesn't over heat often. Decent but not the best.

I just recently bought this amp with low expectations since boss overrates their products' wattage... So far it has worked great with my boss P126DVC subs.. I wish i would have spent a little more money on my wiring kit.. only have a 5 gauge power wire... shoulda bought a 0 gauge..

Overall Great Product...
So Far...

I have got to say that Brendan was the best guy down there I have talked to. Brendan knew exactly what I was after, and was able to answer all of my questions. I will be putting my order in within a few weeks, and will definitely be telling friends and family. Thanks again, Lyn.
