great amp!

Plenty of power around 800 rms at 2 ohms pushes my kicker cvx 12 hard and has great sq didn't think boss was good but man this amp pushes my sub hard well worth money, I recommend this amp to anyone takes a while to fine tune it just make sure u tune it rite and use proper amp kit and good RCA's.

Boss oynx 1800.1 mono amp

This amp is overrated by quite a bit it realistically only puts out about 250 watts RMS if that is all you need then this is the amp for you. There is nothing wrong with it. It works fine but is merely underpowered.

Don't get!

I have two Alpine Type R 10" subs and this amp is nowhere near powerful enough for them, contrary to what the specs say.

AMAZING AMP!

I have had four amps and I have to say that this amp is truly amazing. I have one 12" flat, Pioneer sub that is capable of 1800 watts, max. This amp was able to fulfill that and pump out bass beats like none other. I am truly impressed. The installation was very simple as well. Classic, but simple. It is also very sturdy and durable. My only complaint was with grounding it. I had to ground it with 2" of bear cable in order to get a good enough ground. However, I won't diss on the amp with that because it could have just been my car.

Great product!!

I love thiss amp!! I have it pushing 2 hifi subs and it pushes them no problem!!.. The part I really like is the design the design is freakin amazing!.. It doesn't get hot at all just warm I played about 5 bass songs like Put On, late night tip and more in 90 deg weather and it didn't overheat.. plus I have a custom built trunk so it keeps it cool bc I have fans cooling both of my amps..

Love this Amp!

Been using this amp for 6 months to power 2 15" Boss Subwoofers and it is awesome. The quality of the amp is excellent and is very well built. I have a Jensen amp for my component speakers and this Boss amp blows it out of the water, I should have gotten this amp for those too and I might still. The wire hookups are great because they use set screw clamping so no trying to fiddle with fitting wires around a screw plate. It even comes with a remote bass level knob. I can easily give this amp 5 stars.

great amp

I have two Sony Xplod 1200w 12" sub in a full size explorer and this amp makes both subs beat so hard my windows keep coming off track. So i think some of you are doing something wrong.

Works

This amp is worth the money have used it for 6 months now it's under powered for my 900w rms 12" but it's worth the cost considering.

Great amplifier for the price

I got this amp with a 1,400 watt pioneer sub and it bumps. My friend recently got a kicker amp and sub and mine hits much harder. If you're looking for a great cheap buy, this amp will do just fine with one sub. The remote sub control is great. You can put it almost anywhere (like out of the reach of your passengers). I haven't had it for long but it has yet to shut down from overheating, even with it mounted directly on my sub box.
