Features

  • Power - 1500 Max x 1 @2 Ohms, 750 Max x 1 @4 Ohms
  • MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
  • Class A/B Topology - Class A amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class B amplifiers have no current flowing through its outputs with no audio signal
  • Switchable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
  • Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction
  • Low & High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
  • Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
  • Specs - Dimensions: 10.4 x 7 x 2.3, Weight 5.2 lbs.

  • Nice amp.
Style: 5000W Monoblock
Great so far. Put amp in a 2015 f250, paired with two 8in subs. You definitely need 4g "ofc" wire are bigger. I got 8g and amp keep over heating and going into protection mode. But the amp itself seems to be a great amp so far

  • 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: 1600W 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.

  • Lasted only 2 months
Style: 1600W 4-Channel
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!!! ... show more
