BOSS Audio Systems OX1.5KM Onyx Series Car Audio Subwoofer Amplifier – 1500 High Output, Class A/B, 2/4 Ohm, Low/High Level Inputs, Low Pass Crossover, MOSFET Power, Monoblock, Full Range

The amp works great but the bass boost knobe does not work!

Gotta say I'm impressed with this amp. I upgraded from a Boss 1500w due to my rca inputs going out, typical since the amp was 8yrs old and I put it through hell in those 8yrs. But this 4000w amp is legit, definitely worth the money. It's pushing my 2 15 Skars just fine, got them wired at 2ohms right now. Gonna drop it down to 1ohm and see how it's hitting. Very impressed and would recommend.

While it isn't 4000w like the selection suggests. As long as you read the title and look at the pics you'll see it's 1600w which was just what I needed. Overall helps the subs a great amount. 2 kicker vr 12s and they really hit with it! My bass knob doesn't seem to function but other than that very happy with it!

It's a boss, so the performance ratings are well over exaggerated. But the led lit emblem is cool. Lol. It works well, for the subwoofer I was mating it to, so no complaints. It's a decent starter amp.

I am normally a huge fan of boss audio products, I recently baught one of the boss audio elite decks along with 2 new 800W boss audio elite 10" subs. I had the quiet riot amp before but it just doesnt have the power needed. I baught this one and had to send it back because it clipped from factory. I have it the benefit of the doubt and got a replacement one and completely fresh out of the it just streight doesnt work. I plugged the old amp in before and after and it works. very dissapointed at this. 2 separate amps both faulty at factory. I personally wouldnt suggest this amp, atleast not from this retailer.

Installed in a motorcycle, the LED logo lights up blue and looks great. Sounds great as long as your speakers are the correct RMS rating.

I used this amp to power 2 10’s 1100w subs connected to one terminal and 2 800w 6x9 and 2 400w 6.5 they slap! Only problem is when turning up the gain on the subs would go into protect for no reason but I managed to keep it low and have good bass. It sometimes overheats but I don’t mind it.

NOT 1 OHM STABLE!!! I usually like Boss products, for the money, can’t complain… except for this one! Tried hooking up 4 10” MDX subs 4ohms each) and was distorting! Okay at 2 Ohms but definitely not a 1 Ohm amp! A bit of false advertising on this one. Try the Blaupunkt, I put one in… 4 10s are humming!!!
