Diamond Audio DES400.4D 400W RMS 4-Channel Class D Car Amplifier - High Power Full Range Audio for Cars, Trucks & SUVs - Perfect for Upgrading Your Vehicle Sound System

Diamond Elite DES series amplifiers have been our workhorse since their introduction last year when it was engineered and designed from the ground up. Smaller than the previous generation and constructed with the same footprint dimensions for all models, these amplifiers have been engineered to sound even more dynamic and to deliver optimal rated power at all impedance levels! A ll Diamond Elite DES series amplifiers feature various switched speaker level turn-on options (VOX/DC Offset/REM), utilize the latest digital chipset technology, and provide installation flexibility and all the controls necessary to fine-tune and improve the sound quality of any car audio system. Latest High-Efficiency Full Range Digital Topology - Surface Mount Component Technology with 4-Layer PCB - Continuous Power Output at 2/4 ohm loads - Common Compact Size with Single Sided Connections and Top Mount Controls - Handles HI and LO level input to 12V - Switched Speaker Level Turn On Options (VOX/DC Offset/REM) - Input configuration switch on 4 and 5 channel amplifiers - Remote Level Control Option - Fully Variable Crossovers, Phase and Boost Provide Precise System Adjustment - Bass Boost EQ Up To 12dB
