LOL...Can find just about everything in this forum.
Just stumbled upon this thread and ordered the materials. Something to be said about doing projects on and off the track and although I am not a big audio guy I am certainly looking forward to trying my hands at this DIY.
Thanks again gang!

Big shoutout to @tadda!! I just completed this DIY on my car just to get rid of the rattles/vibrations but what impressed me the most is the quality of sound I'm getting... What a difference. The sound system is pretty decent actually.

For anyone debating, this mod is a MUST and very simple once you start doing it.

Worth doing this on the base model without JBL?

Just went through yesterday and did this. Definitely worth the effort to do. Instead of the speaker tubes I just used little speaker screens to cover the outlet. Next project is the front doors to add wadding to the door speakers. Thanks to everyone that has added input.

ignore all the dog hair 😂

Nice, that is what I would consider doing as well, or the port tube with a screen behind it.

Just finished this mod today. Huge difference in clarity and volume. I will also say make sure to stuff some foam between the panel behind the seat and the carpet. That by itself eliminates a huge portion of the vibrations

I ended up using these links on amazon. You'll end up with way more foam than you need but I didn't find anywhere else to buy a smaller amount cheaper. These exhaust ports also get rid of the need to use speaker grille.

I was thinking of adding smaller, higher horizontal ports - see image. @tadda While I know they will allow less air out, do you think they will still have the same relative effect?

My main reasoning is that the boot mat I want to get has a lip which will obscure the ports.

Thoughts?

After doing this I still have some sort of vibration right behind the seat I'm hunting down. I've already put foam in the one panel directly behind the seat back but there is something that's rattling about head level it sounds like. Any ideas what that could be?

I have a similar rattle.

best I can describe…., as if the speaker cone is lightly touching “something”

when speakers are driven I lose the rattle or sound db is high enough I don't hear it.

At low volume, it is as if the rear does not have enough power to actually drive the speaker….

anyone else?
