Nice Wiring Kit

The following review is for SDSK2, which is a part of the bundle you are viewing.

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

Works pretty good

The following review is for SDSK2, which is a part of the bundle you are viewing.

I bought this product for my trucks doors, and I noticed it's thicker than other sound dampening material I've used before that I paid a lot more for. This is a great product at a great price

Easy to use, good performance!

The following review is for SDSK2, which is a part of the bundle you are viewing.

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

Nvx = quality at the best price.

The following review is for SDSK2, which is a part of the bundle you are viewing.

I'm so happy with all my NVX products. They are always the best in quality and price. No smell and if it's not a lot you can apply it without a roller. (I used my hands and the back of a screw driver to really smooth it out)

Quality stuff

The following review is for SDSK2, which is a part of the bundle you are viewing.

This stuff is very easy to use, just make sure the surface area is clean first, preferably with a mild grease detergent like dish washing liquid. The sheets are definitely thick and can become quite sticky, so plan ahead properly. Best to do it on a hot day where the panels are already nice and hot. Can't say if it made a difference as I changed the entire stereo and deadened the car at the same time.

Awesome deal!

The following review is for SDSK2, which is a part of the bundle you are viewing.

This is my first time using sound deadning and I can tell you that the installation was really easy and the diffrence was greatly noticeable in the sound level. I do not get any rattling what so ever. The product feels thick and of good quality. I would definitely recommend this to anyone trying to improve their quality of sound in their system. I can also hear the diffrence in road noise, it has been greatly reduced, if I had to judge, maybe about 75 to 90 % in noise reduction. This product is amazing!

good product

The following review is for SDSK2, which is a part of the bundle you are viewing.

I have NVX insulation around my front and rear speakers and I would definitely recommend it to a friend. The insulation is pretty thick so be prepared to make holes or cut as needed for proper contact to mounting surfaces. Its pretty solid and sticks really well, and as far as I can tell it helps with sound but I would have to cover the whole car to really compare it with other sound insulation products. I would buy this product again

Good speakers, good price

The following review is for GTO928, which is a part of the bundle you are viewing.

Ordered one day, arrived in two days; pretty easy installation, and great sound, much improved over my '07 Accord's stock speakers. The covers are not very easy to install over the speakers, so I'm using my original Accord covers, and you have to click the button on the tweeter one way or the other and leave it that way, if you fasten down the covers. See what you think. I like them fine.

works well

The following review is for SDSK2, which is a part of the bundle you are viewing.

I haven't used this type of material for a while so nothing else to really compare, but it seems to have worked well. 90mil makes this product one of the thicker ones on the market, and considering the price, I believe this is a very good product. It did calm the resonance of the doors quite well. It doesn't make the car quieter if it is used alone, but it does improve the sound quality of the speaker. It goes on to the metal and plastic surface pretty well. Hopefully it stays there for a long time.

Great for Removing Vibrations for Better Sound Quality

The following review is for SDSK2, which is a part of the bundle you are viewing.

This sound dampening material really does the trick. It removed the vibration from my door speakers and made the sound more crisp and clear. The only downside is trying to apply it around speakers, has to be cut and molded properly for a good fit and better sound, a little tricky, but still doable.

Just get some

The following review is for SDSK2, which is a part of the bundle you are viewing.

I can't tell you how this product compares to others because I've never used a sound deadener. But even just applying the speaker kit made a big difference. I tested the sound after doing one side to make sure nothing was rubbing because it was already a tight fit. The difference in volume was at least 3db from one side to the other with way less rattling. I will be doing complete treatments from now on. Thanks, SE for providing these for free with my purchase.

Bought 2 packs to install in my 4 doors with my speaker upgrade. It does stop a decent amount of rattle that was present in my door panels. I had to split one pack for two doors. Got a decent amount of coverage but I would suggest buying at least one pack per door for complete coverage.

They are exactly what they are and you can never go wrong with nvx products.

Easy to install at the same time as some new door speakers, they do exactly what they're supposed to do.

Very pleased with everything I've bought from Sonic Electronix! They have been the lowest on every single item compared to any other
prices.

These did the job I needed them to do

The following review is for GTO928, which is a part of the bundle you are viewing.

If you are looking for replacement speakers to hook up to your factory amp mine is a 2ohm amp these will do the trick. They sound good and the tweeters are not overpowering.
The only con they didn't come with mounting hardware.

Mediocre

The following review is for GTO928, which is a part of the bundle you are viewing.

I replaced a pair of Infinitys with the JBL. The bass is okay for a 6x9, but overall the mids/highs are tinny and the sound fidelity is not so great. They are passable for the price, but if you are an audio enthusiast look elsewhere.

less doorskin ring.

The following review is for SDSK2, which is a part of the bundle you are viewing.

Put these behind the speakers on the door skin and it significantly reduced the resonant frequencies in the vocal range, which before treatment made the speakers have a bit of reverb effect during speaking vocal range.
Much better. Doesn't sound like I'm in a sports arena anymore.

Seems like it's helping.

The following review is for SDSK2, which is a part of the bundle you are viewing.

Got this free with new speakers, so opted to use it during the install.

With the factory speakers, when cranking up the volume, I could hear the door outer door panel resonate when outside the car. After installing the new speakers and this Deadener, while I got my music cranked, and it seems like it's louder than I was playing the old factory speakers, I no longer hear the resonance of the outer door skin when outside the car.

So, it seems to be doing its job.

However, time will tell if it stays in place or falls off. Or worse melts and creates a mess.

Very Nice!

The following review is for GTO928, which is a part of the bundle you are viewing.

I installed these in my front doors and rear deck in my 2010 charger and they sound really clear and loud. I do not have an amp hooked up to them but am planning on getting one soon. With these I have a pioneer avh-x4700bs and with the right settings, these speakers have great potential. I would recommend these speakers to anyone.

The following review is for GTO928, which is a part of the bundle you are viewing.

good JBL GTO928With the long history of professional audio equipment manufactured my JBL, it is no surprise that the Grand Touring Series (GTO) produce some of the finest sound available for car speakers. By integrating the majority of JBL's top car speaker technology, these speakers are able to effectively deliver truly stunning audio, while keeping the price affordable for everyone. For those that are looking for a quality car speaker that will not only sound great, but also keep more money in your pockets. Put your trust in JBL and these Grand Touring Series speakers.

NVX sound deadening works like magic!!

The following review is for SDSK2, which is a part of the bundle you are viewing.

At first I was very sceptical because I've always used a different brand that cost twice as much. Thinking that it cost more because it's better had been my biggest mistake. When it comes to this part of any audio install, always always take the extra time to eliminate any rattles and vibrations. When you're spending money on top of the line audio electronics always compliment your install with NVX sound enhancing/deadening products. I promise you'll be amazed at the sound quality difference.

JBL GTO928 6x9 2 way coaxial speakers

The following review is for GTO928, which is a part of the bundle you are viewing.

When I got these I thought they would be like some other JBL 6x9's I had but I was pleasantly surprised seems JBL has lifted their game a bit these are quality units unlike the previous units these almost look like they are made in the USA but we know better don't we I would say better quality control and a bit better management I am currently fitting them so no idea on the final sound but so far very happy.

I highly recommand these speakers, they sound incredible and the bass is so deep. If you don't believe me, probably is because your stereo receiver is not so good 'cause they are amazing. JBL's are the best in every way.

Awesome Speakers

The following review is for GTO928, which is a part of the bundle you are viewing.

These are some great sounding speakers, JBL has made a great quality product once again. The mids, highs and lows are just awesome, if your looking for a better speaker to upgrade too, look no further. I've had Alpine, Infinity, Polk and Rockford, and these are right there with the rest if not better. I have the GTO928 in the front of my 2005 Chrysler 300 and the GTO938 in the back. I'm telling you guys the BASS hits hard on Deep. No cons on these babies here, do yourself a favor and get a pair. I will be purchasing the NVX JAD900.5 so i can make these puppies really sing. And the price, don't even think about it, Sonic Electronix every time hands down...

Much better than expected speakers

The following review is for GTO928, which is a part of the bundle you are viewing.

I bought these JBLs because I know they'er gonna be good speakers. For the price these are without a doubt the best bang for your buck. the lows are deep and the mids and highs are crisp. Installation was a bit of a chore but once installed they work great.

Amazing sound, if they are amplified!

The following review is for GTO928, which is a part of the bundle you are viewing.

Bought these to replace the stock 6x9s in my 2007 Toyota Corolla. Running them solely off of my JVC head unit (22 watts RMS/channel), I was not too impressed with the sound quality and they distorted very easily. I think this is because their low 2.6 ohm impedance was actually causing the amp in my headunit to clip.

BUT, a couple months later, I added a small 4 channel amp (Clarion XC1410) and the difference is night and day, now that they are getting a healthy 70 watts or so of RMS power) The mids and midbass are amazing with these, especially the punch from kickdrums, and the highs are clear without being tinny. They also put out a surprising amount of bass, almost as good as having a small subwoofer.

Overally, these JBLs are a really good value for the money, if given the right amount of power ( 45-100 watts each). If you plan to just run your speakers off of a stock or aftermarket stereo, I would look for a lower-end, less power-hungry speaker.

Smart, good sound and thrifty

The following review is for GTO928, which is a part of the bundle you are viewing.

For the price these are hard to beat if you are using an amp and need a little more output. The 2 ohm impedance helped stretch my amp up to 115 watts per channel instead of 70.

From 100hz and up these have been fantastic. Highly recommended. Installed in a Dodge Ram QC ran off of a Soundstream pn5.640D as rear fill.
