Key Specs
Continuous Watts x Channel @ Ohms: 50W x 4 @ 4 ohms
Amplifier Class: AB (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
Number Of Channels: 4
Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)

Outstanding amp for the price
I have been a car audio fanatic since the late 80's and have owned several great systems with (what is now old school) Fosgate, Orion, Zed built Autotek, Kicker, Hifonics, and other high end components. I am now into ultra-fi single driver horns etc...so I know good sound.
Had some certificates saved up and decided to give this cheap amp a shot.
I was very pleasantly surprised by how clean this amp sounds (especially after dialing in my JVC head unit's EQ and other settings). It doesn't have the headroom or raw power of a higher end amplifier, put it pushes my 4 Fosgate 6x8s and Jbl sub fine. It sounds way better than the head unit.
If you want good clean sound with solid bass, this amp delivers. If you're wanting a super loud system, with booming bass, spend more and get a better amp.
