JL Audio C5-650x + Sound Dampening

Excellent product

This is great material and is very easy to put on with a heat gun!

Great package deal value.

I recieved this as part of a package deal. It is enough to cover the lid of my 98 Civic sedan trunk. This will clean up the sound of your lows by decreasing noise (rattles, distortion of sound, etc). This is the first step in noise reduction and everybody should start here.

I doubt it will create a noticable increase in sound from your speakers.

Very flexible, sticks like crazy! Easy to work with.

Excellent

These speakers were use in the faring of my HD Road Glide. Amazing sounds that these speakers produce. I would recommend these speakers to anyone and put them up against any others.

Great Price and Product

I found the price great for the product I got. Installation was very easy, product sticks very well (Remember to clean/prep the surface). I noticed a difference right away in my music as well as overall noise level while driving on the highway (Doors done - trunk is next). Not the thickest sound dampening out there but it def. helps :)

The battle against rattle

Got the sound dampening door kit with some speakers, the installer put it on the rear deck of my vehicle where my two rear speakers and factory sub are. The difference is night and day, expensive but quality, good to get with speakers or a sub.

excellent sound quality

i have these in my blazer hooked up 2 a jl 450/4 amp and they pierce my ears. i would highly recommend these to anyone who wants a set of nice sounding speakers

Blown away

Just got these speakers and was just blown away. I've installed it in the rear doors of my Toyota Venza with the OE head unit. What big difference from OE speakers. Now just waiting For my Pioneer Head unit and getting ready to order a pair for the front doors. Probably later upgrade with a JL Audio HD 900/5. Thanks Sonic for low prices and quick shipping.

Great Speakers

Awesome sound, amazing bass for a 6 1/2" speaker.
Clean and crisp sound with amazing detail.

amazing

I put a set of these in my trailblazer front doors
unbelievable sound quality and amazing drumbeats
would highly recommend
planning to add a pair of zr800 as well

Sound Great

Very happy with these. They have a very full, rich sound compared to the Hertz I had in my other vehicle. And no distortion with my setup even when it's hitting low.
