Maybe a long shot but is anyone here able to fabricate some Front Door Speaker Adapters to mount a 6.5 or 8 driver? Preferably made from thick Acrylic, HDPE, or PVC. Let me know if youre able along with your price. Thank you.
If you don't have bose you can cannibalise your factory speaker. Cut our the driver and basket, then use it as a mounting bracket for new 6.5". Worked well for me.
