About this item
Product details
- Power - 1100 Max x 1 @ 2 Ohms, 550 Max x 1 @ 4 Ohms
- 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
- Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
- 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 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

The Boss
My Pioneer 800watt went dead and was going to replace it and not really sure if it was the amp after checking everything. Was going to buy the same but the price is up there. Then I saw this at Walmart for under $50 and thought to give it a try. Had my doubts but for the price, couldn't go wrong. Boy, was I shockingly suprise. Are you kidding me? It exceeded all my expectations. I have a 1400 watt subwoofer and this baby rocks it hard with thunderous bass. Very pleased. Thank You finally, Walmart!.

The easy way to lose hearing early
I have this paired with a pioneer 251sx 10' subwoofer and it sounds great in my extended cab silverado. Took about a week to adjust it right. Make sure you don't have your gain set to high, I also have the bass boost switch turned on and the bass remote turned all the down and it pounds! Great for a single 10" or "12
