Easy to use and apply

The following review is for CSM, which is a part of the bundle you are viewing.

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

The following review is for CSM, which is a part of the bundle you are viewing.

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.

Sounds Great!

The following review is for CSM, which is a part of the bundle you are viewing.

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.
