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

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.

Good for the money and size

The following review is for KP-42N, which is a part of the bundle you are viewing.

Bought these babies for my rear doors on my 96 4runner. They sound ok, but when amped they blow, lasted about 4 weeks and now they seem to play about one frequency. Upgrading to 5-1/4" for more sound and cleaner sound.
