NVX FRING4 2 Piece Universal 4” Self Adhesive Foam Speaker Ring Kit with Foam Base Pad

Worth the price. Did make a significant difference had for over a year and still holding on with its glue super easy installing. Sound is put where it's needed.

Nice material, It was easy to install both the octogon ring on the speaker face and pad into the door facing the magnet.

This works perfectly, but the opening is a bit smaller than the 5x7 speaker. I stretched it a little to keep it off the speaker itself, it is fully covering all screw mounts though. Works perfectly in my ford ranger door, it buts right up to the back of the plastic. Note, I shaved off the old plastic surround from the back of the door panel that was originally in place for the for the factory speakers so this would work. Much cleaner sounding that it was before, I am very happy with the result.

These foam rings significantly improved the overall sound and bass response of my aftermarket rear speakers. They were a perfect fit for the rear speakers in my 2001 forester. I did not have to use adhesive and they seal against the speaker cover perfectly. I didn't end up using the center foam pieces since its pretty tight in the door.

This is supposed to be for a 6x8, the NVX website states 6x8 or 5x7. I tried to use this on the 5x7 door speakers in my mustang. What a joke it’s too small for the 5x7 so I don’t see how you could fit it to a larger 6x8. Total waste of time and money. Don’t bother with this regardless of what any internet expert says. These things are junk but unfortunately you don’t realize that until you start to install and by that point you can’t return them for a refund.

Okay, first let me say that I am an audiophile. I drive many miles a week and listening to great sound is important to me.I have a 2013 Ford Explorer Limited with the premium stereo. I've upgraded all of the speakers, I put sound deadening throughout the car and already loved the sound. However, when playing the music loud, the doors would make noise, it drove me crazy.... So I researched what I could do and saw these on Amazon. For the price I said what can I lose?Well, I lost nothing and gained a lot!After changing all of the speakers including the subwoofer, sound deadening the car, the upgrade sounded amazing, the bass was tighter and I was able to raise the volume without distortion.When I added this, I was surprised, it made the bass more stable, more direct if that makes sense. Before adding this the bass was tight, but airy. This completely took that airy sound away.Now, if you have the power bass Ford speaker upgrade, those already come with a speaker ring attached, I was worried at first but these fit perfectly....Now, the only annoying thing is, and I say this with pure frustration, removing the top film to get to the sticky tape is so freaking frustrating. Thank God I wasn't drunk, so warning, do not drink before Installing these because you will be screaming and cursing. So good luck!With that said, these made a major improvement in my stereo, this is definitely not snake oil! They fit my 6x9's without any issues...

Didn’t fit my 6x9. Had to get creative with the center foam. I don’t notice any difference in sound quality.

Used this product for my rear door speakers to ensure the sound get to the cabin. Works great and was very easy to install.

Nuce product but never used them the baffles work better
