Mazda RX8 Bose Amplifier Repairs



International postal repair service for Bose car amplifiers




This 7 Channel DSP controlled amplifier can be found in all variants of Mazda RX8 from 2009 onwards. It has a maximum power output of 240 Watts – located behind the drivers seat – behind a plastic cover , it’s easily removed.

It’s worth noting that the Bluetooth kit runs through the amplifier – so the amplifier is ‘on’ the minute the door is opened.


Coding

No VIN coding – variables set by model number.

What Fails and Why

After spending many hours reverse engineering this unit we have built up an extensive knowledge base on the circuit. We have improved the design and have developed a ‘repair/reliability’ kit which we fit on all units. This enables us to confidently supply a lifetime warranty on all repairs.There are no known faults with the headunit – all issues are with the amplifier.

Common symptoms are ;

  • No Sound
  • Machine gun noise through speakers
  • Loud white noise
  • Random loud noise when door is opened

Repair process

All units are tested first to ensure faults exist – after which the unit is stripped and rebuilt.

After a final reprogram/check and data errors cleared, the unit is sealed to protect the components from moisture.

We currently have a 100% success rate with these units – so long as they haven’t been water damaged or tampered with.

Our repair work seems to reach everywhere – the latest Haynes manual for Mazda features one of our repaired units in their ‘strip down’ guide

We can also …

reprogram any unit to ‘be another’ i.e.. convert a Mazda 3 to a Mazda 6 – any variant , any model.


What we can’t repair

  • Heavily water damaged units
  • Units that have had poor repair attempts
