Customer Ratings & Reviews

good product

Really stops the rattling that comes from having the punch from the kiker speakers i have installed in the doors of my car.

Easy to use and apply

I used this product in my rear component speakers (Alpines) for the mid-range woofers in the doors to shield against vibration and they do a good job and the speakers sound great for it!

Cache CSM

These came in a package deal from Sonic
with JBL GTO series speakers one of the decisions why I bought the GTO speakers, easy to use. Currently installing the sound system but having used similar products before these will make a good speaker sound better.

Great product

Worked good, stopped the rattling. Deeper bass.

good stuff!

I bought this in a combo package that Sonic put together with a set of hifonics components, the zxi65c. i liked it, i havent heard any rattling from my speakers. works well, i recommend it.

Sounds Great!

I installed the Dead Shield Sound Dampening Material under all 4 of the speakers I replaced in my truck and the stereo system sounds great, better than I expected.

Quiet.

These speakers are QUIET. It's unnerving how weak they are. Even miss to upper highs are quiet. I have them on a 4-channel amp that goes to 100 rms 200 peak, so they're not being underpowered, but if I turn them up more than twice the gain of my front 6" speakers they don't even begin to match the volume! I know they're small and therefore aren't expected to push much when I comes to lower mids, but I've heard cheap ipod docks sound louder. There's simply no excuse. Maybe I just happened to get a defective pair. Should be noted, however, that I blew a front speaker once and these managed to survive at the same volume setting, so they seem to be fairly durable and the rated peak might be understated a bit.
