  • 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.

  • 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. ... show more

  • Decent budget amp
Style: 4000W 4-Channel
Decent amp for the price, haven't been able to play with it for optimal performance. Set up for a bench test and am happy with the sound quality. As I'm not looking for a huge bass gains this makes a decent budget amp for a simple system.

  • Excellent sound
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.

  • Worst amp known to man kind
Style: 1500W Monoblock
If you want a low quality, non performing, amp buy this. If it says 1500 watts the most you will receive is 130 watts max output. Save your time and money and buy a Stinger 1500 watts rms.

  • Good price for this amp
Style: 4000W 4-Channel
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.

  • Powerful
I like how everything hooks up on one side, the power of this amp is awesome I'm able to power 4 2ohm 2500watt 12in. Subs to the max and never gets hot. Best amplifier Boss has came out with yet and I've been following them since the 90s
