Hifonics ZS653 with Sound Damping - Customer Ratings & Reviews

Don't go without it

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

Good product

NVX SDBSK2 Premium Stealth Black

Thick and heavy. I was suprised with the actual quality. For the price they’re great quality

NVX SDBSK2 Premium Stealth Black

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.

NVX SDBSK2 Premium Stealth Black

Easy to use and reduced vibration, allowing clear sound coming from my door speakers.

Great value

I installed these on each rear door of my 2005 Silverado. Could really hear a difference in sound quality.

NVX SDBSK2 Premium Stealth Black

Great product, Sonic Electronix is great. I've ordered a few things from time to time and have had no problems. I get the item quickly. I ordered this and was so pleased. I ordered another set. Works great.

Great value

I loved it. Very easy to use and very satisfied at the site

Nice coax

I'm very pleased with these 6.5 coaxes. They are paired with the 6.5 components of the same series. Have them running off a Kenwood x700.5 and they sound great!!! I decided to use the flush mounting brackets(included in the box) and all 4 6.5s all are snuggly nested in the NVX Baffles I bought right here at sonic.

Really good for the price.

Performs as well as speakers that cost more. Will be buying these for my car, as well.

Very good

I've bought Hifonics speakers before so I know their sound quality is great for such a low price. Another great set of speakers. Very clear.

Hifonics ZS653

Good, clear sound for the price. Great speakers for starter or budget build!

Great Sound Great Value

Second pair I bought along with the 4x6 2 way. First in my 06 S10 second in my 02 Blazer. Great sound and value. S10 speakers going strong after 2 years.

will not fit a 97civic

This is a good-sounding low-cost speaker, but be careful they have a large mounting ring that will not fit in the door of a honda civic without being trimmed.

Sound deadening

Makes the speakers sound great and looks good to plus doesn’t blind you.

Good deal

Bought a pair of kickers and they came for free, doubted them at first but it really does help in muffling the rattles from the speakers.

Awesome

Clean and clear sound! Definitely a great buy. And sonic e. Was quick and reasonable

GOOD QUALITY AND EASIER ON THE HANDS!!!!

I got this small pack to finish my daughter's 2020 Camry after I had already used the foil-backed version. It went on just as easily and stopped the license plate and gas gap door rattle. A big plus for me was it didn't cut my hands shreds as the foil did.

Good quality sound deadener.

Not enough to cover an entire door but enough to add enough mass to make a difference. Peel and stick.

Nvx sound mat

Awesome

I installed these in my 2004 Jeep Grand Cherokee, they needed to have holes in order to fit my application. That being said, they sound great and are an extreme value.

Not bad for the price

These 6.5s are actually holding up well, got 2 pairs wired to a 1000W Pioneer 4-channel and they sound pretty solid.
