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.

Great Service. Great Sound!

My speakers in my grand prix were stock pieces of crap. I outfitted my car with the mtx terminator speakers front to back. I ordered these on a thursday. Received free shipping and got them the very next day! The speakers are amazing. Very crisp clean sound. I absolutely highly recommend these speakers. I will never ever buy from anywhere but Sonic Electronix when it comes to car audio. Love my speakers and will be buying much much more from Sonic!

Balance and Value

I have two sets of these in my 2004 Cadillac Deville. Clear and balanced sound. Buy, buy, buy.

good

I got these and the 6x9s (which are awesome). Good buy, quick delivery too, like 4 days.

Good Sound/Good Price

I replaced the stock speakers in my 2009 FreightLiner Cascadia with these MTX Speakers,Front and Back,, and after all,,it is a better sound, even with Bass and the stock Stereo can even put out the wattage that is needed,,plus they fit right in where the stocks use to be,,Good Quality for the Price...
