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.

Crutchfield Customer Review (What's this?)

Nice product but did not improve sound from new speakers, I had to remove them after hearing the difference. I installed the back speakers with these baffles and the front speakers without. After hearing the difference, it was a no brainer. I pulled the baffles for triple the bass output.

Pros: Easy to install, looks great when done, for sure protects the speaker.

Cons: Didn't make the new speakers I purchase sound better made them sound worse, had to remove them (the speaker baffles).

Size matters

Written By Bryan H, Wisconsin on Monday, June 01, 2015

Crutchfield Customer Review (What's this?)

Like others here the size was almost too big, felt like I needed a shoehorn to squeeze these into the speaker cutouts

Pros: cheap, though material

Cons: smallish, might impede some installs since clearance may be an issue.

Boom Mat 6-3/4" Speaker Baffles

Written By Anonymous, Connecticut on Sunday, April 19, 2015

Crutchfield Customer Review (What's this?)

I installed the slim line 6 3/4" baffles with JBL 6 3/4" speakers. The slim baffles were more than enough depth for the speaker. However, I probably could have used 6 1/2" baffles because the diameter of the baffle flange was too large. They fit, but barely. I had to squish the baffle to reduce its diameter to fit the hole in the door, and give the speaker flange something to sit on. I tested the new speakers with and without the baffles. The baffles definitively helped the clarity of the sound by reducing the reverberations in the door cavity.

Pros: Protect the speaker Improved the clarity of the speakers

Cons: Seem to be manufactured too large

Boom Mat 6-3/4" Speaker Baffles

Written By Mark, Michigan on Sunday, April 12, 2015

Crutchfield Customer Review (What's this?)

Boom mat 6 3/4 where easy to install but I cannot actually do a before and after because I installed them while installing a new set of speakers.

Pros: easy to install with new or oem speakers. The material they are made of is thicker than they look in photos.

Cons: The only question I have is that when installed they create a closed box enclosure behind the speaker. Most car speakers are desinged to work best in free air.

Inexpensive speaker protection

Written By BrianP, Georgia on Monday, December 08, 2014

Crutchfield Customer Review (What's this?)

Boom Mat protects the back of your speakers, is inexpensive and easy to use. I found out too late that the full-depth version I got wouldn't clear the window, but that was easily fixed and only compromises the protection a little. (To test, remove the interior trim, roll down the window, and with a rigid rule, measure from the inside surface of the door to the rolled-down window glazing.) If your Boom Mat extends beyond that, just take some scissors and cut the back off, allowing an extra 1/4" or so for window clearance.

Pros: Inexpensive, Protects speakers, isolates speaker frame from direct contact with door structure.

Cons: You don't know your clearance until AFTER getting inside the door..

Replaced factory Jeep sub. There was a lot of air space, in such a small enclosure. These were the perfect size to solve that issue.

Pros: Slim-line are perfect size for Jeep sub box

Cons: no complaints

Stupid me

Written By everyone is an expert, minneapolis on Thursday, April 24, 2014

Crutchfield Customer Review (What's this?)

Unfortunately I used to work in plastics and injection molding. I am not amused or impressed. I purchased these only to prevent damage from water leaking onto the new speakers. Acoustically I should know better. The full or slimline will work in my car. I give these a 1 because Crutchfiled got the correct part in the box. They were only mildly crumpled up. The order was on time enough and I am happy so far with the other items. I got 6.75" speakers and 6.75" BOOM BOOM MATS. But for some reason the speaker falls to the bottom of the baffle and misses the flange one is instructed to trim. STUPID ME. Fortunately, knock on plastic, there is no trace of rain leaking into my doors after 14 years. There is actually stock noise damping insulation and sealing in the door already. I would send these back. However, the extra pollution for $10 is just not worth it. If nothing else I can wear them as dunce caps for not analyzing properly.

Pros: These might make okay planters to sprout seeds in. Lightweight food and water dishes for the dog. Might be dishwasher safe and microwaveable. Might be able to cut them and use them in a loudspeaker/horn cabinet.

Cons: Have not figured out how to suffocate myself with them yet.

Boom mat seems like a gimmick

Written By Chris, Arkansas on Sunday, July 28, 2013

Crutchfield Customer Review (What's this?)

Probably wasn't needed but used a set to try them out. There was a lot of air space where I used them, so basically used them to reduce it.

Pros: Supposed to protect the speakers from the elements

Cons: Making holes in them to mount the speakers. Pretty much have to install the speaker twice.

Must have for door speakers

Written By Kestas, Frisco TX on Thursday, April 09, 2009

These are a must have for door speakers. They reduce road noise and give a more consistant base with a much fuller rich sound.

Easy to install

Written By Duncan, Albuquerque,NM on Monday, November 10, 2008

This product is a great way to protect the new speakers in your car door from the weather, as well as providing better sound. It is very easy to put this product behind the speaker just before you install the speaker.

Hands-on research

What's in the box?

  • Two acoustic foam slim baffles for 6.75" speakers

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: 3.5"
