DES 1-Channel 500W RMS Full Range Class D Amplifier

DES 1-Channel 500W RMS Full Range Class D Amplifier

Diamond Elite DES series amplifiers have been our work horse ever since its 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 provides installation flexibility and all the controls necessary to fine-tune and improve the sound quality of any car audio system.
