About the Boom Mat 6-1/2" Speaker Baffles

Boom Mat baffles protect your car's new speakers from moisture and dirt. Mounted behind the speaker, the baffle forms a mounting seal that also improves sound clarity by reducing panel vibration that could transfer to the speaker.

Boom Mat baffles protect your car's new speakers from moisture and dirt. Mounted behind the speaker, the baffle forms a mounting seal that also improves sound clarity by reducing panel vibration that could transfer to the speaker.

These baffles will protect your speakers. In many applications we recommend that you cut a hole in the bottom of the baffle, or remove the entire bottom of the baffle, to maintain good bass response while still protecting your speaker from dirt and water damage. Call one of our Advisors if you have questions — they'll be happy to share their expertise with you.

Product Research


Overview: These acoustic baffles are designed to be placed behind car speakers to protect the speaker from moisture and dirt which can damage speaker components. Along with providing a sealed chamber, they also form a mounting seal between the speaker and the mounting surface to eliminate panel to frame resonance. Baffles will improve door acoustics by reducing road noise and vibrations transferred to the back of the speaker cone. The baffles are pliable and can be compressed to fit most applications.

  • Maximum Depth: 3.25"
  • Thickness: 0.25"
  • Flange Size: 6.875" x 6.875"

Customer Q&A

11 questions already asked

Could these be used as "back box" with in-ceiling speakers?
[ MICHAEL J  Feb 10, 2021 ]
1 answer
These help protect the speakers from road noise and debris, and help project the sound. So your application in this case may be a wise decision.
[ JOHN J  Feb 11, 2021 ]
Will these enhance performance of door speakers? (97 S-10 project)
[ no83vettes  Jan 20, 2021 ]
3 answers
Yes they will. For a more cost effective way to keep sound from your new speakers creating resonation to the rest of steel door shell, it's a great choice. The alternative is to line the exterior door skin inside, and also the inside shell. That is the superior to have it done. The Boom Mat baffles are a great way to start. You can't go wrong with them. If that doesn't suit you, Crutchfield has you covered for the next step!
[ DAVID  Jan 21, 2021 ]
Yes you will be satisfied
[ STEVE  Jan 21, 2021 ]
Yes, very much so. Makes speaker water resistant and also it's like putting your door speaker in a box.Enter
[ Dustin  Jan 20, 2021 ]
Varying comments on impact to sound quality. Could I simply cut them in half to block some elements and avoid negative sound deadening it's how ever one describes impact to sound?
[ Jeremy  May 12, 2020 ]

When I removed the factory Bose speakers from my 2004 Avalanche, they had a hemispherical rubber/foam shield above them built into the speaker. I got these to recreate that. If you are just worried about water dripping then sure. I would mount them as is and see if you like it, then start removing material.
[ Aerohokie  Oct 21, 2020 ]
Don't think that would help...Only installed them on my boat for speakers protection...
[ MARK  May 12, 2020 ]
my jl audio 6.5 are 2 9/16 deep. what would you recommend 2.5 or a 3 for the speaker depth for the Foam speaker baffles?
[ stephen  Apr 16, 2020 ]
2 answers
My particular application allowed me to have the deeper set. I bought them to keep my JL c3 from leaky windows 2015 Honda Fit. This allows more distance from the corner for the wire to exit. Both will help preserve your purchases. Enjoy.
[ Cory  Apr 18, 2020 ]
I would go with the 3in speaker baffles. I love mine.
[ Scott  Apr 17, 2020 ]
Would these help with any bass response if installed in a Harley batwing?
[ Stuart  Sep 16, 2019 ]

Minimal difference in sound quality
[ Cory  Apr 18, 2020 ]
[ mauri  Sep 24, 2019 ]
considering using these for 6.5" ceiling speakers for low level background music. Thoughts?
[ haileymon  Aug 02, 2016 ]
2 answers
These baffles will help a LITTLE with sound but more importantly they will keep debris out of the spider and motor mechanism of the speaker for longer use.
[ RUDY  Aug 20, 2017 ]
I used this product when I installed new speakers in my old truck and it seemed to make a noticeable difference. Can't really address how they might affect ceiling speakers, but I was satisfied with them in my application.
[ Stewart  Aug 03, 2016 ]
Will these baffles also work for 6 3/4" speakers?
[ Justin  Oct 20, 2021 ]
1 answer
Yes, they certainly should. They are made of soft, pliable material that should easily conform to a speaker only .75" larger.
[ steve  Oct 20, 2021 ]
How are the baffles fastened to the back of the spaeakers?
[ Reed  Apr 26, 2020 ]

i just dropped mine in
[ Charles  Apr 27, 2020 ]
They are not connected to the speaker, I connected them to the door frame
[ Tim  Apr 26, 2020 ]
We poked screw holes through them.
[ Kelly  Apr 26, 2020 ]
I don't they improved the sound
[ John  Apr 26, 2020 ]
The baffle will go into the speaker hole. And the speaker is fastened to the front
[ ROBERT  Apr 26, 2020 ]
Are these good for the front speaker box in a 2015 Jeep Wrangler Unlimited?
[ Kurt N.  Sep 06, 2015 ]

For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.
[ Krissy  Sep 08, 2015 ]  Staff
I've read differing opinions on if you should cut a hole in the bottom of these baffles or not. Are there applications where I truly should or should not cut a hole?
[ Todd  Mar 26, 2015 ]
4 answers
I would think you need to cut a hole in it either way, cause you have to get the wires through. I just cut about an 1" slit in the bottom of mines.
[ Robert A.  Mar 28, 2015 ]
Its probably up to your tastes. I initially cut the bottoms out and installed them. I found the sound muffled and the volume reduced too much. I then cut out part of the sides and the sound improved so I left them in.
[ MIKE  Mar 28, 2015 ]
As I recall (been a few years), I poked a hole through just to feed wires. What I can tell you is that these definitely improve sound and amazingly keep sound focused within the cabin as opposed to making the door pocket resonate and buzz. I always think people next to me are annoyed by the loud music, but when I get out and close the door, it's not loud outside at all. (I do have insulation panels)
[ KEVIN  Mar 27, 2015 ]
Do you want to use the door cavity as the "cabinet" for your speaker or a little tiny cover? The cover without a hole will turn a very small volume into a sealed speaker cabinet, which will limit bass response.probably not the best choice.
[ AARON  Mar 27, 2015 ]
