Key Specs
Continuous Watts x Channel @ Ohms: 1200 x 1 x 4 ohms, 2400 x 1 x 2 ohms
Maximum Watts x Channel @ Ohms: Handles up to 1200W RMS (continuous) @ 4 ohms or 2400W RMS @ 2 ohms (This is the maximum load the speaker, subwoofer or amp can drive.)
Amplifier Class: D (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: 1
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: false (Bridging an amplifier increases the power it supplies to the speaker(s).)
Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below 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).)
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).)
Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

Audio
Number Of Channels: 1
Signal-to-Noise Ratio (SNR): 95 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
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.)

Overpriced
The KX series is great and everything, but definitely overpriced - you can get a lot better watt per dollar value with a lot of amps out there. I highly recommend checking out the Hifonics Brutus X-14 series...

High quality high output
Not the cheapest but a good value for what you get. If you buy this amp with the pkd1 wire kit they will warranty this amp for three years! It is NOT rated for a 1Ohm load. If you need an amp for 1 ohm load you have many options but not this amp.
