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.

NVX SDBSK2 Premium Stealth Black

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

Good product

Sticky and did hook well to the cars body . Got it for free with my speakers purchase. Sonic electronix for life

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.

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.

NVX SDBSK2 Premium Stealth Black

Perfect fit an very fast shipping.Good list to choose from to fit my car.

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.

Excellent

I have the alpine system in my jeep wrangler. I wanted to upgrade. These speakers blew my alpine oem system away. Sound way better. Clear and loud with more base! Stock HU cant wait to amp the system!

Great product for the price

I've yet to install these speakers but I have other speakers from NVX and I'm very satisfied with their products. I know these 6.5 component speakers will be great!

Sound Great!

These are my first set of non-oem speakers, replacing the oem tweeters and front speakers on my 2005 Pontiac Vibe with the moon and tune package. It's hard to find 2-ohm speakers that work with the OEM amplifier, back speakers, and subwoofer so having these available is clutch if you're a Pontiac Vibe owner.

Installation
Installation was made difficult because the speakers did not come with any instructions which made it difficult for someone who had never installed speakers before. Installing the tweeters was easy enough, to get them to fit under the OEM tweeter covers I removed the tweeters from their housing and glued the metal back to where the OEM tweeters had screwed in.
Installing the speakers was much harder. The kit doesn't come with any of the screws so I ended up going to the hardware store with the plastic housing and finding a screw and nut to fit every hole in the plastic housing. I then drilled holes in the car door for each hole and screwed the holes in. The OEM speaker holes are a little larger then the fittings, its important to fit the speaker as low as possible or else you can't close the window all the way on the driver side. On the passenger side the window will hit the speaker about an inch from fully closing, although a couple months in I haven't had any problems. Since the speaker hold was a little bigger than the speaker, I used clay caulking to seal up the gaps after running the speaker wire through the gap. It took a lot of force to insert the speaker connectors into the speakers, I thought I was going to break them, but after some painful pushing they slid in.

Tweeters
The tweeters are a significant upgrade over the OEM ones. A dramatic increase in detail and sparkle. The tweeters were a bit overpowering when the crossover was set to 0db (drowning out the mids), but switching to -3db is perfect. A really nice feature. They work together really well with the speakers.

Speakers
Very crisp detail with a punchy bass. They sound great at any volume and don't seem to mind being driven hard. My only criticism is the bass can sometimes overpower the mids, especially since i already have a subwoofer. I guess that could be fixed with EQing, but honestly things sound good as they are.

Overall I highly recommend for anyone trying to find a set of speakers that they can plug and play into their Pontiac Vibe with the moon and tunes package.

Love that I got it for discount with speaker purchase. Works like a champ!

Love NVX!

NVX has been the only speaker I've been running since I bought my first set when they came out. Specifically these 2 ohm 6.5 component speakers are amazing, especially amazing for the price. I have them in both of my cars and amped. The mids and bass these speakers produce is incredible. Even with the volume all the way up these speakers are crystal clear. For the money I don't know of any other speaker that will come close. These speakers act like some super high-end super pricey brands that are double or triple the price. I will always recommend NVX brand to anybody

By Richard on September 22, 2025 Verified purchase

Awesome!!

I have a 2005 Toyota Sequoia with the factory JBL sound system. I just replaced the front to speakers/tweeters in the doors. Huge difference!! It sounds way better than the factory system. These speakers are great too because they are 2ohm speakers. This means they are plug and play in the 2005 Sequoia! Thanks Sonic and NVX!

By Hayden on November 29, 2024 Verified purchase

Great sound

They sound great. Going to add another set in rear doors

By Anthony on May 23, 2024 Verified purchase

Makes sense Works perfect

I put a square behind ea. door speaker and a square on the inside of each pod and it made a solid difference, especially for the pods. The music sounds better, no hint of an echo or slight vibration that I'd get before insulating with NVX SD. Pods/speaker boxes should really come insulated from the factory. Install some squares behind your speakers and you'll hear the difference.
