How to Improve OE Sub Bass Quality and Eliminate Vibrations

[Lil Grey Supra]

Rotary Heart - if you do not want to go through the trouble of cutting and stuffing to line the walls of the enclosure.......try speaker baffling like I did. I'm not a patient person like tadda so I went the cheap and easy route. Works like a champ!

That's the only part I couldn't muster to do. What did you use? Was the baffling just the cotton candy like material? Did you just stuff it in there randomly?

finished up my subwoofer mod, thanks to this this thread. Thank you Tadda!
Huge improvement over stock. Here's how mine turned out. Going to start on the dynamat process this weekend.

@tadda, where do you pull the schematics from? Looking for some of the usb area so I may route a cord to the glove box.

Great initial write up, I'm finally getting around to this mod. Thank you all.

Yep - the cotton candy type baffling. Stuffed it in and tried to ensure full coverage. Works great!

Awesome! I'll try that.

I couldn't get the 1" template cutout in through the 3 little port holes. Figured the top two would be easier, but I didn't go to the extent of removing the sub top panels.

Did you just stuff the whole area or just either side of the ported locations?

I filled the entire space loosely with batting. Base response improved and the opened ports allow for exhaust instead of vibration

Excellent. Thank you for the info.

I did the same, it is so much better now. THANK YOU TADDA FOR YOUR TIME IN FIGURING THIS OUT AND THE WRITE UP!!!!!!!

@tadda, do you think aftermarket amplified direct replacements, band passed at 500hz-80hz, would require these ports still?

yes...

I finally got all the components in and did the install as shown on page 1. I went with plastic/metal tweeter covers, but purchased the 2" ports as well just in case for options. Sounds 100% better than before and now I have no desire to replace those speakers. The only thing I'm considering is a standalone sub for handling the lower frequencies, but I like my hatch space, so not sure if I'll ever get around to it.

I like what you did there and might copy. Agreed on the improvement. I added this:

Heres the link to those tweeter covers. I had to hot glue the grill to the frame since they free float and are meant to be held by tension once tightened.

How did you mount your amp and how did you get the signal for it?
