So I thought I was in the clear after I got my tweeters nicely mounted with their swivel mount and all where the factory ones were minus the grill covering (putting matching carpet behind them so they look nicer)...

Then I finally got the whole door panel off to find the factory speakers weren't the same size as my JBLs... They are about a 1/4" larger it looks like, and the mounts will not fit my jbls without some serious modification. I am planning on trimming the old mounting bracket I have down and glueing it to the existing one, but I was wondering if anybody has had this problem in the past and had any suggestions before doing so. The other alternative would be to cut two plywood rings and use those as mounting "adapters".

Thanks.

FWIW it's a '98 Safari

You will be better off making mounting rings. Glue and subwoofers don't go together very well. I know a lot of people do that but its not something that lasts very well.

You could glue wood rings to the plastic speaker mounts and then after it drys just mount the speaker to the wood with wood screws !
You would'nt have to worry about the wood ring coming loose because theres some really good glue out there
I used to use glue called E6000 but then i could'nt find it anymore and then i found some at wal mart that works just as good called the amazing goop
If you use this glue you probally want to wear a mask or i ussually hold my breath and put it on real quick and then get out of there and mayby leave it in your garage awhile with good ventalation to let the fumes air out!! Also try not to get it on your hands if you can help it

Thanks for the suggestions; I'll get the camera booted up and take pictures of what I end up doing for reference hopefully.

I am pretty sure I'm going to make up a thin mounting bracket. I am going to try to find a thin sheet of plywood or something pretty rigid that I can work with easily, cut it into a ring that goes on the mount I have and mounts the JBLs, and just bolt it into the mount like the old speaker was with a rubber gasket or maybe just some hot glue in the middle to keep it somewhat air tight.

My only big concern with it is that the grill on the door fits right up against the delcos that are in there, so I gotta make the mounting bracket pretty thin to be sure everything will still fit.

Think plywood would be my best bet? It doesn't have to be pretty just functional because its behind the door grill (hopefully).

I hope we're talking woofers and not sub woofers, but either way, just make sure that the cone doesn't hit the door panel at it's extended point(when the cone is protruded out at it's farthest point).

What wood do you guys think would be the best to use? I was thinking 1/8" or 1/4" plywood. I figure I should be fine on size at that width (would compensate for how thick that seal is around the delcos I think) and I thiiink it would be strong enough. I would mount the wooden ring ontop of the mount, then possibly mount the JBLs behind the plywood; just to guarantee it wouldn't hit the door panel (making sure its not hitting the window on the other side as well)

...Never worked with MDF though also. I would think with the way the force is gonna be applied plywood would work great, but wanted some thoughts on the matter from anybody that knows better.

mdf is the standard for speaker enclosures. the thickness is based on what size speaker you are using and the amount of force it needs. 1/2 inch mdf should do the trick for you. its fairly inexpensive also. here 20 bucks for a whole sheet(4x8).

ps mdf is also what some house cabinets are made of. think of how heavy all your dishes are together sitting on there shelves in the cupboard

Well, It'll have to be thinner than 1/2" to clear the door panels unless things get messy, in which case I'll just drill out the rivets and go from scratch. I know MDF is a bit heavier, but wasn't sure if it'd work as well in this application due to the thickness I was looking for. I might just go to home depot or somewhere local and play with the materials and see what I can find. Hopefully I can dig up the camera and take some pictures of everything for reference.

instead of wood you can always use plastic. much stronger than wood at the same thickness. home pepot carrys it as well. its usually in the back off to the side of the wood isle. ask for acrylic or even stronger, but much pricier is lexan,or polycarbonate if you dont like brand names. the latter is also known as bullet proof glass
