Powerful Performance

* Monoblock amplifier for subwoofer use.
* 400 watts x 1 (1 ohm) continuous, 800 watts x 1 (1 ohm) dynamic power. CEA-2006 Compliant specifications for true, accurate power ratings.
* 300 watts x 1 (2 ohm) and 200 watts x 1 (4 ohm) continuous power.
* 1 ohm stable design can drive even the most demanding subwoofers.
* Power and ground terminals accept bare wire up to 4 AWG. Terminals use standard #2 Phillips head screwdriver- no more hex wrenches to lose or strip!
* High-speed MOSFET switching power supply and high current Bipolar Output Transistors pump maximum voltage and high current to your speakers or subwoofers.
* Double Layer Fiberglass Epoxy Printed Circuit Boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. Efficient layout packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.
* 6-Way Smart System Protection (SSP) circuits: Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto-Standby Mode ensure safety, reliability and durability.

Great Looks and Functionality

* Anodized extruded brushed-aluminum cover for maximum heat dissipation and great looks!
* Cast aluminum textured end caps for optimized heat dissipation and hiding of connectors. Solid aluminum logo and model panel back lit in cobalt blue.
* Adjustable 12 dB/octave low-pass crossover (30-250 Hz).
* Switchable 8 dB bass boost at 40Hz for extra bass thump.
* Switchable 24 dB/octave subsonic filter protects ported subwoofers.
* Switchable 180° phase inversion for easy sub to main integration.
* Variable input gain optimizes match with different signal sources (250mv to 7.5V).
* RCA Outputs for easy daisy chaining of other amplifiers.
* Mounting hardware with rubber isolation grommets and extra fuses included.
* Light Bar/Fan Output- Connect an optional LED light bar or cooling fan for custom installations.
* Multi-Color Status LED gives instant information on amplifier operation.
* Remote Subwoofer Level Adjuster included.
