FRING68 2 Piece Universal 6x8" and 5x7" Self Adhesive Foam Speaker Ring Kit with Foam Base Pad

I bought new speakers and was pissed bacuse they sounded bad. so I did some research and these came up. so I added them and it made my speakers sound 100% better. I could probably use sound matt all over the door. but if you want a cheap and easy way to make your speakers sound better this is it.

I used nvx sound deadener to deaden my WHOLE truck put sound good audio block off plate in front doors and put Polk audio DB series speakers in front and rear doors with the nvx speaker rings around them and they do exactly what they say that are supposed to do I love NVX products ordering the NVX big 3 upgrade next

Easy to install and great sound improvement 👌

Bought these for my 2012 F150. Supposedly guys on forums run these or reuse the factory plastic/foam seals when replacing door speakers to improve sound quality. Bought a pair for the front doors along with a set of MB quart speakers. Pretty sure the new speakers made the majority difference in sound quality on my truck but I am by no means an audiophile. But these are cheap enough to take the risk on if your ears are sharper than mine.
