uxcell a15011200ux0430 Black 10m 33ft Length Car Speaker Sealing Tape

As advertised

Excelente producto muy bueno

Door speakers and sealed well

It works.

Added after market speakers and tweeters in the front and rear of my car. Helps reduce vibration and improve sound quality

Not a good product. The pictures are very deceiving and the foam is very thin, you have to do two or three stacked runs in order for the speaker to make a good seal. Buy something else.

I bought a new q bomb speaker box and a 12"jbl speaker.the box has like a rhino spray on it the stuff for truck beds..there was no way I was mounting this speaker bare on the box..I use it on the inner edge of the speaker and also a strip on the edge of the speaker cut out hole.. made a perfect seal cushion when I tightened the bolts..perfect for my need..thanx

Highly flexible but does not bunch up. Adhesion is excellent but (just barely) will release to allow you to reposition if you do it fast enough. For the price very excellent. On the thin side but enough to create an air seal. This will not fill huge gaps. I ended up going with this over the foam that came with some very high dollar component speakers.
