Did this as well, it does make the bass a bit cleaner, previously bass distortion happened a little below 50% volume, now it’s happens around 2/3 highest volume. Still has rattles though :(

Did you do the foam and acoustic wadding too?

I've been able to play songs I previously wasn't due to obscene rattling. I don't get anything now at near intolerable levels of volume

Yes I did. I’m wondering if it’s the subwoofer grills.

Has anyone found a trunk liner that has a shorter back wall height that would still allow for round ports?

for example the weather tech clearly would cover them, unless I made rectangular cutouts, no chance of that coming out nicely lol

I just trimmed my WT liner and installed a screen in my ports to avoid objects rolling into the sub cavity.
This mod is a must do if you don't want to upgrade your entire system. Bass response is much improved. Just be sure to Dynamat the entire rear compartment to lower the chances of rattles.

Doesn’t look bad with the trimming, thanks for sharing!

The JDM Toyota Supra mat works.
I didn’t even know this thing existed lol, I like it, been thinking how I can secure stuff from sliding around and this appears to do that. Not sure it’s as good as weather tech as far as protecting from a spill of something.
Thanks for posting this I’ll look into this more

The mat is actually "spill proof" and seems water resistant to the touch. Also, it has a small lip around it to contain spills. While I haven't spilled anything on it yet, I'm pretty confident it will work as advertised based on its feel. Also, the netting points are standard on our cars in Australia and the net is a stock Toyota Supra net (nothing to do with mat underneath, FYI).

I see that now, I thought your mat somehow had the net included. I’ll pick up this net regardless thanks.
Can’t find a place to buy the mat itself, do you have a link?
Here is the net, I think:

The net looks right - just be aware that as far as I understand, US cars don't come with the mounting rings needed and they don't come with the net itself.

I bought the boot mat - sorry, trunk mat lol - from Greenline motorsports but after a quick look at their site, it doesn't seem to be available from there any more. On my invoice it was listed as "Toyota Luggage Soft Tray - Toyota GR Supra RZ - DB42 (B58B30) (08241-14020)." I believe it to be an original Toyota Japan part, but I could be wrong. I can tell you it wasn't cheap though!

And here's a better pic of both, pre-Tada subwoofer mod.

I picked up a cheap off brand one in Amazon for les than $70. Hurts less to cut it up and easier to clean if something spills since all the channels go in one direction.

You can buy F3x rings they fit. Also if you live by a salvage yard , you can get the hardware pieces including the correct torx bolts and D rings from any F3x BMW and they will fit. You do need to trim the carpet on top as they are not precut for the holes, but the holes are there
