Just wanted to find out what others did, I am replacing my kickpanel speakers although the foam behind them is somewhere between OK and powdered. Just wanted to see if people put new foam back in, or would something like Reflectix give off a better sound?
I do not think that your foam is stock there. My end of March 68 coupe does not have foam there. However there is a pop riveted piece of black molded plastic there, on each side. Lou.
I saw the pop riveted piece Lou, mine were cut out to fit in radio shack speakers, so i had to fabricate those back in. The new speakers from Electro-tech are EXACT replacements and they have the tang on the speaker that hangs on that piece you describe that someone cut out of mine.
Thanks for the feedback!
I'm glad to see the foam gone only serves to trap and collect moisture.
You have some great looking body mounts I would avoid foam as you have.
My June. Built 68 has the same plastic upper half cups as Lou.
I like the baffle idea. I know the acoustics was poor back in the day compared to where we are now.
I must be loosing so much sound in the fender.

You need some air-space behind any speaker to allow it to function properly. But, you also need to minimize support area resonance; so you need some sound deadening material behind the speaker.
I'd suggest that you just put some 1" thick fiberglass insulation (paper backed) in that area before you install the speaker. That should do the job. (Fiberglass toward rear of speaker)

Thanks for the compliment on the condition of my body mounts Marshal. I didn't get a chance to check that area before I bought this adventure about 6 months ago, and I feel pretty good about what I have lnspected since then. The bubba fixes have been fairly easy to undo. I also have a June build....the 19th.

Paper backed?
That would cause more issues down the road with the moisture that gets in there.
Just insulation by itself is fine, but I preferred using the baffles because of moisture.
The firmer the 'baffle' the more resonance problems you will have. But the biggest issue with a baffle is the loss of adequate air-space behind the speaker which will tend to limit rearward speaker cone movement and interjection of sound distortion and volume loss.
You can do what you want. If that area doesn't see moisture (and it shouldn't, if front end is sealed and drainage paths are clear....whole different issue here), paper backing will not be a problem. Plus, backing on insulation is intended to seal vapor from getting to the insulation. In my mind, it's a non-issue with what I suggested.
