Wanted an upgrade to the High Performance System, so had the following installed by Ultimate Audio in Bromsgrove:
Audison Prima AP 8.9 Bit DSP 520W Amp
Audison Voce Component Speakers (fronts)
Audison Prima Coaxial Speakers (rears)
Eton 10" Subwoofer
Skinz sound deadening and wave diffusers for front and rear doors
Speaker Adaptors, upgraded speaker cabling, etc.
Pictures of the fit are attached - have to say the service was exceptional from Karl at Ultimate Audio and the end result is an amazing sound quality now.
The system provides a rich depth of sound but with crystal clear mid and vocal range, and at all volume levels with no distortion.
The fact that you simply cannot tell from inside the car, as it's all to the OEM fittings, makes the final result even better.
