How to Improve OE Sub Bass Quality and Eliminate Vibrations

[pav911]

Just in case there are others as new to this as me, I’m going to add what I’m learning along the way.

It helped to lay all the cut dynamat pieces down for a test fit before sticking anything.

I also realised I’ll need some sort of cleaning solvent to prep the trunk area before sticking down the dynamat.

yes...it will allow you to pull up the rear of the cover a few inches to make it easier to insert center foam block...

I honestly don't see how I can get a 2" foam block up there. Or do you mean put noico up there? thx

I used 2" foam....foam compresses...You can also cut the foam to a 1"x2"x6" block...

Another thing I've learnt is there's all sorts of foam. I think I ended up buying the stuff that doesn't compress all that well. it's quite firm.

It appears as if you have the correct foam from the pic you just posted...just cut the foam block to a 1"x2"x6" block and insert

Greetings one and all. I'm a car guy and have owned 2 earlier Supras. Now looking to maybe buy a '21 3.0 Prem.
I need your help if anyone knows the answer. I've seen many vids on the "issues" with the vibration caused by how the speakers are mounted, poor insulation, etc. My question is: Are you all talking about the 2020 model...and is the 2021 exactly the same OR did Toyota "happen" to fix this issue?? If I'm going to buy the '21 I need to know if I'm going to face this very same issue.
Thank you all for any help and knowledge you have with the new Supras.

Same design. It’s just kinda meh
Not a big deal to me. Definitely not even in the top 30 reasons to buy or not buy.

I'd definitely recommend taking your favorite music to the dealer and spending some time with the car and its audio system. I really regret not doing this, as I wouldn't have bought the car knowing what I do now. Of course where the audio system sits in your list of reasons to buy a car is different for each person so it may not bother you that much. Without a doubt this is a great car to drive and I'm trying to best to just ignore the rubbish audio system.

Everyone is different. It can definitely be improved. I didn't even turn the radio on during my test drive. lol
