Vehicle DSP Amplifier Package
Why choose this product?
BMW HiFi S676 DSP amplifier upgrade
Replace the factory BMW HiFi amplifier with the ESX SE800.6DSP while retaining the original head unit and vehicle speaker wiring.
This package is for pre-RAM BMW vehicles with factory HiFi option S676. The supplied vehicle-specific harness connects at the original analogue amplifier position in the rear, avoiding the head-unit and underseat-woofer rewiring required on Base Audio cars. The amplifier independently powers and controls the cabin speakers and BMW underseat woofers and is supplied with a pre-loaded BMW tune.

- 6 × 80W RMS at 4Ω or 6 × 125W RMS at 2Ω
