Need Educated opinnions on mounting new door speakers

[SpeedEuphoria 10+ year member]

Hey in the past i have just kinda reused the stock plastic piece for the door speaker.

I have been reading and wanted to do a better install this time. Was planning on using a MDF ring and some modeling clay, to mount the new ones but i have some issues with the current car.

Basically the factory plastic speaker ring is big and really offset aiming the speaker up and back toward the seats.(pics to follow)

The plastic ring angle sinks the one edge into the door while the other sticks out a couple inches. Also the plastic ring is pretty large as the opening in the door is ~10" wide by 8.5" tall

Also on the plastic door panel on the inside of it behind the speaker grille it has a shroud that directs the sound out the grille instead of bouncing around between the panel and door frame(again look at pics)

Just using the stock ring that was made for 6 3/4" speakers, I have to cut the door a little to align the speaker with the shroud(no pic of this hard to explain, but can prob get a pic). Basically the speaker needs to go towards the hinge more but hits the door.

It looks to take some creative engineering on my part to get the same design as stock with MDF or possibly fiberglass and I really like the stock placement/aiming of the speaker.

I am wondering if I just make a mdf ring and put that on top of the stock plastic ring and put some clay under the stock plastic. I would also make a MDF frame that goes around the big opening where the 4 screws attach to the door to strengthen the door opening also.

Do you think that would be sufficient in your educated opinions??

Here's the pics:

The easiest approach would probably be to layer some fiberglass on the stock piece to stiffen it up, then decouple it from the door just like you would mdf.

thats sounds good, I have fiberglass handy

so your saying ditch the MDF ring all together?? Only prob is that stock was made for 6 3/4" and mine are 6 1/2" so I need something on the mounting surface to mount the speaker to so may need a 1/2" ring on it either way with the proper cutout hole

So putting a MDF framing around the opening from behind which would screw/bolt to the stock piece would kinda defeat the purpose of decoupling it even if I used clay in between correct?

If the 'frame' does not touch the sheet metal, or does but clay is used between them, it will be fine.

gotcha and thanks

I just made some MDF rings for the speaker, going to put them behind the plastic to mount the drivers. Fiberglassing them in place and basically fiberglassing the whole plastic mount.

I'm going to ditch the other MDF frame idea

Then I'll just clay the strengthened plastic to the door

Should work nicely

I would post pics when I'm done but it will pretty much look stock
