## Questions & Answers

**Q: I need speakers for a 1997 crown Victoria front and back**
A: I recommend getting some speakers

**Q: Are they like a box to make bass better?**
A: I do feel like the bass is more solid and better and eliminates the "boxy" sound that the door enclosure normally produces. I think it eliminates undesirable resonances that distord the clarity of the sound.  If I had to chose, I would install them again.  One warning, they come in different sizes and you may need to cut them to fit your door cavity.  When I cut the first baffle, it was a bit lose and then it produced an undesired vibration between the plastic of the cavity and the foam baffle where they were both surfaces were barely touching.  To correct this, I cut the next baffles in a way that they fitted tighter in the cavity and eliminated the noise produced by the vibration.

**Q: How thick are they?**
A: In some vehicles where the speakers mount on a middle steel panel and the whole shebang is then pressed against a speaker grill molded into the inner upholstered door panel, check the clearance carefully, as it varies a lot and this little thing can add enough to make a firm panel fitment a bit difficult at that corner. You can always trim the plastic grille area. This is rare, but might be important.

**Q: Would I / should I use these if I am mounting the speakers in individual cans?**
A: I've noticed less pronounced lower frequencies, which is ok for me in trade-off as I use it to combat damging effects of water leakage from a bad window seal. If by 'can' you mean a designated enclosure; I would skip this and line with polyfill if anything. In a bare door cavity you should expect achieve cancellation of the reverb from highs and mids bouncing off metal. These are essentially 'individual cans'.

### ⭐⭐⭐⭐⭐ Best upgrade ever for $12 per pair of speakers.
*by P***T on November 25, 2016*

These are straight bad arse. I am tickled that for less then $50 I was able to install these on 5 speakers in my Tahoe. I took out the Bose speakers (I know it sounds like a stupid move), but I swapped them for coaxial speakers of a much higher quality and the same ohms. I installed these Boom Mats after seeing them at the auto zone and WOW, what a difference. I actually uninstalled these baffles just to see how much a difference they actually made and again, WOW. The speakers sound more faint and a good bit less base without these baffles. The key is all in how well you install them. Order black silicone in a tube, this is necessary as you need to pierce the side or bottom of this baffle in order to route the speaker wires thru the baffle. Once they are thru, take the black or clear silicone and pack it around the base of the wire to reseal the hole the wire made. LET THE SILCONE DRY before you try out your system. I let it sit over night just to ensure the silicone was super dry as I was not trying pull door panels off again and reseal the holes. It is critical the baffle says sealed and is air tight. There are a few installation videos on YouTube, spend 30 minutes reviewing them to get familiar with how to install them. If you do the install wrong it will not sound like anything special. Good Luck.
