Door speakers - I need to glue them in!

[MikeyV]

Now that you're here because of my zaney title - here's the problem. Car is a 12/70 built 1971 Mach 1.

I have the door speakers with the 8-track option stock. The drinker's side speaker has always had this terrible rattle - it was the metal perforated metal speaker screen rattling against the plastic grille in the door card.

I recently removed the door panel with zero difficulty (thanks to other threads here - the best) and got the speaker out.

Turns out that the metal grille is separating from the fiber spacer - and the fiber spacer is separating from the metal speaker frame.

Does anyone have any experience as to which type of glue might be used to fix this? I'm certain both parts are glued together.

Here are some photos of the separation, and also some extra just showing the speaker and part numbers for reference here on this forum - for anyone who might look in the future. First photo is the metal grille separating from the fiber spacer, and the second one shows the fiber spacer separating from the metal frame. Where it's still glued, it's very firm still.

Thanks for the help on this one - and on prior things. Cheers!

(((PS - looking for one or two Door card grilles - I need the one with a single vertical bar! I can trade an NOS 72/73 piece that has the two vertical bars)))

I haven't tried that one, yet. Thanks for the recommendation, it's on my shopping list.

I would put some butyl rubber tape in between the speaker and the grill

That will keep it from rattling and could the cleaned of if need be

I used 1/4 plywood to mount the door speakers...........actually the wood improves the sound in general. Got this tip from an aftermarket custom sound system installer.

I used ABS plastic as unlike wood it won't rot as it may get wet inside a door. Which is honestly overkill for a garage kept car, but wanted to do it once and never worry about it again. Also used a foam baffle on backside of speaker to keep it dry also.

Checking back in - thanks for all the good suggestions. I've been looking at replacement speakers - just like - in case - and It's good to know you can but just about anything that's a bit smaller and mount it on another plate (wood or plastic or whatever) to avoid drilling into the door.

I ended up using that LocTite glue - worked great. It's east to apply cause it's thick, and you have at least 5 min to fuss about before clamping it. It's not cyanoacrylate glue - it looks like old Testors model glue - but minus the fumes. Smells like nothing really. I first bonded the fiber spacer ring to the metal frame, then separately glued the metal screen on top of the fiber spacer.

Note that the speaker cone is attached just like any speaker - ie. the cone lip glued to the metal frame and then the fiber spacer ring/mounting pad on top of that. The loose fiber spacer brought up the cone as well - so care is warranted when pulling on it. It's a good thing that I didn't pull it completely off - it would have ripped the come down at the base.

Anyway - nice and tight now - and stock looking. I'm happy to continue to run the original speakers in the old gal. My car has the stock 8-track running some Waylon.

Thanks for the advice - This forum is such a great resource. I hope somebody benefits in the future from this thread.

Marine speakers - great idea. My cones were pretty "crispy". Had one small tear that I repaired. My car had been parked in a semi open shed for 38 years - a barn-like structure. Somehow the speakers survived.
