Vehicle DSP Amplifier Package
Why choose this product?
BMW Base Audio DSP amplifier upgrade
Upgrade BMW Base Audio from its shared four-channel factory layout to independently controlled front, rear and underseat-woofer channels with the ESX VE900.7SP.
In Base Audio, the front-door speakers and underseat woofers share the front outputs of the factory head unit. This package separates them into a true six-channel system. The supplied loom bypasses the original shared subwoofer circuit, reconnects the front-door wiring and provides OEM-style plugs plus dedicated speaker cable to the underseat woofers. The required plugs and wiring are included.
The 2 metre ISO loom keeps the installation in the cabin and can use the OEM power wiring. The compact amplifier can be hidden around the glovebox or passenger footwell.
The amplifier is supplied with a pre-loaded BMW tune as an appropriate starting calibration.

- Seven-channel amplifier with eight-channel 96kHz DSP
- 5 × 100W RMS plus 2 × 200W RMS for the underseat woofers
