Pushing 2 15's no problem
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.

Great amp for price
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!

Lasted only 2 months
I purchased in the beginning of September and installed in October 2025. It was easy to install. It was working fine but all of a sudden while driving I smelled something burning and found out it was the amp. Waste of money as it’s only been 2 months.

Works well
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.

NOT 1 Ohm STABLE!!!
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!!!
