Now, the fun part. Here is how the dash woofers mount, in little pods:
So I made some neat baffles for them too:
And guess what? The C3-650 basket would not fit. That corner on each enclosure that sinks inward, hits the basket no matter how you turn it:
The only solution I could come up with, was nipping those tabs off the outside, and securing some Toyota/Subaru 6.5" ABS adapters I had laying around from previous installs.This spaced the woofer out enough to fit, and there was surprisingly still enough clearance between the dash and the woofer. So check the speakers off the list, they are installed!!!
This is the gear from today's adventure, JL Audio C3-650 and C3-525:
