Boss NXD4500

At first after i heard that BOSS was a low end brand, i was a little skeptic when purchasing this amp. However, even though they are a little over rated, this amp is an excelent add on to my sound system. i have 3 rockford fosgate P3D412's hooked up to it at 2 ohms and they sound perfect. I was used to having a hifonics amplifier hooked up to 2 12" rockford fosgate HE subs, but this however is 100 times louder and rattles my frame. Boss may not be a top quality brand, but don't let peoples bad reviews fool you. When it comes to the ONYX series, you will be happy.

This amp is amazing. Just make sure that when you ground it to your vehicle that the ground is solid. Have no other problems. Keeps the bass going and no shorting.

It was a little difficult to learn to use, being as I'm a novice. But it hit harder than any amp I've ever owned. The only real drawback I found was that after about a month, it stopped working. I don't know what's wrong with it, but if I can fix it, I'm putting it in my truck. I mean, who needs their hearing?

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.
