Review: 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.
Review: Enjoy! - Customer loved it sounds great.

## Features

- POWER - 1500 Watts Max x 1 @2-Ohms, 750 Watts 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
- 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
- SWITCHABLE BASS BOOST: Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
- 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.
