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 sound

would refer to anyone

Good for the money and size

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.

Good value

Fast delivery and product works good , the price was cheapest I found
on the internet

power acoustik

Nice sound, works and sounds better with an amp.... Very nice speakers.

Power Acoustik KP-42N

I purchased these spkrs to replace the front door speakers on my 90 Honda Accord work car. The old ones buzzed and crackled since they were 21 years old. The Power Acoustik speakers installed just like the stock speakers and sound great. I also bought the 6X9's for the rear deck. The best thing about them is the price. The price is cheap but the speakers are NOT. I would recommend them to anyone wanting a much better than stock car speaker.

watch out....3 OHM speaker

i bought this product not reading carefully and noticed thius speaker was 3 ohm...and you CANT hook this up to any aftermarket of factory radio cause it will fry thier onboard amps....so unless you have an amp to hook this up to..i would recommend looking at another product
but when i had this thing hooked up it did bump pretty well for a 4in speaker

A+

very good speakers they sound better than my pioneer 4x6's very durable, low to no distortion and the woofer cone is top quality .price and sound are great

not bad

these sound pretty good for the price. only draw back is on the second day the wire leads going into the back of the woofer start coming loose and makes the speakers pop. i only got 22w rms and 50w max going to them so i dont think it should be happening to a speaker that should be accepting more than that. fixed it with some gorilla glue and all is well. these things scream highs and put out a surprisingly good amount of mid-bass. overall i would get these if you know how to glue the leads back in.
