I had Noico installed in all 4 doors behind speakers, inside doors and around/inside door panel edges. Amazing difference! Highly recommended. Bose audio now sounds the way it should: clean, punchy, loud, deep. Tweeters also sound better, don't know how, but they are crisp and clear. It feels like my amp gained extra 100W RMS of power.
Outside sounds are now almost gone, tire road noise is less intrusive. I can actually hear my engine revving, previously it was barely audible since other sounds had more presence. Plastic rattles are also gone. I would recommend throwing a little Dynaliner foam or similar stuff inside around door panel edges. Mine were rattling even after Noico was installed.
I am very happy I decided to try Noico before I pulled the trigger on messing with aftermarket speakers. I am now very happy with my Bose going forward.
I’ve been looking at different sound proofing materials after realizing there are more than just two or three popular brands. I had intended on using B-Quiet, which is comparable to Dynamat, because I used it on my last vehicle. I only used the butyl rubber liner with the aluminum skin last time and it was only 1.5mm (59 mil) thick. This time I plan to use a similar liner combined with a foam decoupler.
I am looking at the following products:
B-Quiet
Noico
KILMAT
Siless
Second Skin
B-Quiet publishes their performance specs in plain sight on their website, but I can’t find any specs for the other products. The only thing I can find is the temperature rating, which should at least give us a general idea of how effective each product is. The temperature ratings are as follows:
B-Quiet (63 mil) = -76F to +293F
36 sqft = $99.99
Noico (80 mil) = -49F to +212F
36 sqft = $65.99
KILMAT (80 mil) = -49F to +212F
36 sqft = $56.99
Siless (80 mil) = -50F to +395F
36 sqft = $49.99
Second Skin (80 mil) = -70F to +450F
30sqft = $209
So, just going by temperature range alone, Noico and KILMAT are equally as bad, with KILMAT being the most affordable. In 3rd place is Siless, but it’s low price makes it attractive. In 2nd place is B-Quiet because it performs better with a 63 mil thickness than others do with 80 mil.
1st place easily goes to Second Skin, but the price will drive most people away. The cost to apply just the 80 mil liner would be nearly $800 and I can see that price doubling when adding the foam mat.
Siless seems to have the most cost effective solution at about $150 to apply the liner throughout the vehicle. Add the foam mat and the entire package will cost around $300 for the whole car.
