CANOPUS Car Sound Deadening Mat, 80 mil 5 sqft, Pack of 5 Sheets, Butyl Sound Deadener Mat, Audio Car Sound Dampening Material for Car Trunk, Door, Floor and Ceiling, Silver

I installed a stereo system in my vehicle bit the bass was rattling the door panels and it sounded annoying. I decided to purchase these mats and what a BIG difference! The installation was super easy and now I don't hear any rattling and the sound is clear and crisp now. The mats are heavy and of very good quality so durability isnt an issue and I was surprised that they didnt have a strong smell.I must say that they're worth the money and the customer service is awesome! I highly recommend

Very high quality and great value and very easy to use. Very help with vibration reduction and very sticky. I would buy again as a great value and so easy to apply.

Really works! I used this on the outside of a metal fuel pump enclosure for a boat diesel heater. The fuel pump would make a "thump thump" sound which is normal but disturbing for sleeping. After covering the metal enclosure with this the sound was gone. This is an "off label: use for this product but it is heavy, sticky, and sound deadening. Works.

Bought these for my Camry, they work great. Easy to apply and made the road noise noticeably quieter. I will probably get some for my doors as well. Great product.

Like the 80m thickness' and for the roof, I think blk. is the way to go till you get a headliner then you cover it up. But the thing I don't like it that they fold each sheet, it hard enough to roller it on now you have to roller out where it was bent, this makes it harder to smooth out, yes I know, well you will cover it right? but putting it on or up with the bends just makes it harder to roller flat. Just more working it out then on.

The media could not be loaded. After doing some research I decided to go with the Canapus sound deadener for the stereo build in my c4 corvette. The material lays down well and sticks great if you roll it. Once I got the system in I was pleasantly surprised at how good of a job it does keeping the sound in the car and reducing vibrations.

This CANOPUS Car Sound Deadening Mat is very similar to Killmat.I have used Noico mat for my 2010 Camry, Killmat for my 2015 Camry, and Amazon basic mat for My 2021 RAV4 Hybrid. I used up 36 sq ft Amazon basic mat for my 2021 RAV4. I needed more mat for my 2021 RAV4. So I ordered 18 sq ft of CANOPUS Car Sound Deadening Mat. I installed Canopus mat mainly on wheel well of my RAV4. All these mat suppose to reduce metal vibrations. They are probably all made in China. They are all similarly butyl based. None of them claim the percentage of other components. However, they are slightly different. The differences are mainly in adhesion when apply to the metal surface.They suppose to reduce car road noise. While car road noise are mainly generated by tire rubber slapping on the concrete or asphalt road. The sound frequency of road noise are mainly in 800Hz to 1200Hz. It wound be better if any of these manufacture to test what frequencies these mat are most effective. The markers of these mats are demonstrating effectiveness of these mats with a patch of mat on a gong. Applying a small piece of mat can eliminates the ring of gong, which are ringing at 300 and 3500 Hz. The hard part to reduce car road noise is that noise penetrating into car from every where, it hard to completely apply these sound deadening mat to every metal surface of car. The main penetrating point should be rear wheel well. That's why all SUVs are nosier and cars unless the price difference is five times and more. Applying sound deadening mats are very labor intensive, manufactures will not spend that much labor to apply these mats to their cars at the labor cost of $100 or so per hr. However, apply these mat only 25% metal surface will give maximum return of investment. The more will only give diminishing returns. 2010 and 2015 Toyota Camry comes with about 16 sq inch of similar sound deadening mat. While RAV4 dose not have any mat on the four doors, and only has a little on the 5th door. That's one of reasons makes Camry quieter stock than RAV4. After applying these mats, the doors on RAV4 as well as Camry feel much solid when closing with a solid thump, not an empty tin can sound any more.This Canopus mat are similar to Killmat when apply to the metal surface, are stickiest among these four mats. Noico mat is medium sticky. Amazon basic is least sticky. When handling these mat, disposable gloves are must for Canopus and Killmat, recommended for Noico and optional for Amazon basic. However, when applying these mats to the metal surface, a heat gun or hair dryer is must for Amazon basic, recommended for Noico, and optional for Canopus and Killmat. I warm the metal surface before applying the mat to the surface. I recommend a roller for application, especially for Amazon basic.I have put Canopus and Amazon basic mat in -20C freezer, both of them are still malleable and suppose to work in winter time. However, in -80C freezer, both of become brittle. In -80C, only metal and wood can still maintain most of characteristics of normal temperature anyway.I have made my RAV4 quieter by at least 3 db using these mats and other sound insulators.If I need to buy again, I would recommend Canopus and Killmat when they are priced similar.

put these on my stainless steel sink, helped make it more solid and minimize ping
