However, as the damage was so severe and deep, decided to test it using my NSX in order to inject real world ACG and IG noise plus vibration and thermal shock.
Carried out more than 30min test driving session and happy with the result.
Back light also tested.
Please ignore my clock and CCU display illumination control as I disabled them long time ago so that it always stays at max brightness regardless of the lighting status.
USA Spec CD changer port adaptor connected to test the ACC line.
As always, when everything works, to my hearing frequency sensitivity, the OEM package is well beyond my requirement and no need for the aftermarket head unit, speaker, AMP, etc.
Back to Bose AMP.......
Some of the caps were still leaking heavily.
Lots of cleaning, scraping and re-soldering…..
Uprated the caps, quick bench testing including the amp gain control and happy with the result so new hot melt glue applied.
Thermal compound applied and ready to put the AMP back in the speaker box.
Again, tested it for more than 12Hrs including thermal shock and gain control.
Happy with the result so time to return the head unit and the speaker box.
Thank you for using my service and hope the owner will enjoy the nice sound system again on his/her NSX.
Now back to the other audio head unit…..
It's really big challenge.....
And I already have another NSX waiting for my emergency service….
