Stereo question

[SS_EURO]

I want to know of any cheap effective was of killing the super loud vibes from my trunk. They tend to get so loud the bass sounds like a buzz instead of a boom. I tryed adjusting the trunklock but it only helped a bit not enough to make me happy. Dyna matt is too much money for me to spend on my trunk. Any ideas?

Filled my truck with it. Works the same or better than Dynamat Extreme yet costs a quarter the amount

strip calk by 3M cheap as hell, or a application of standard rubberized under coating, KAR products make some good stuff and affordable too, a couple of layers of this will stiffen any vibes.

On that last site link the metal or aluminium face or covering is just that for looks it doesn't really absorb or reflect any sound. It does however reflect infrared radiation. My question is how much dB do you think it dropped by using that aluminum looking tape, how thick is the stuff, what it made out of really, it is hard to tell, looks like ducting repair tape to me..

That stuff is mostly intended for thermal applications, but just happens to be supierior to the standard stuff. All major sound damping companies have some variation of it, and it's usually their best type. It is like regular sound damping except with a layer of aluminum foil over the top. It's usually like 50-70 mils thick. It's not for look, because in 99% of applications it is covered up by panels.

That is a good deal, 50 square feet for 100 bucks, I wish I knew that before I bought 3 gallons of noise killer.

I'm not really sure what i want to do. The rubberized coating sound like it would work but I want to do it right the first time. Maybe coating over the top of b quiet will be the over kill I'm looking for. You guys don't understand how bad the car vibes. I had to put silicone on the mounting holes of my head light to get them to shut up. I added screws to the plastic inner fender wells cause they made noise and the rear bumper is almost about to be ripped off permanantly. I hate the vibes and the noise. It kills the performance of the stereo so much.

It is not for looks it is for reflecting heat. The product is about 1/8" thick and is a butyl membrane. It is very dense and kills sound by converting it to heat. It is the exact same product as dynamat but not overpriced. Dynamat was the first company to market a sound deadning product because of that they figure they can charge a premium. If you compare the 2 you will see the B-Quiet is more effective at the temperature your truck enviroment usually is.

The difference is amazing. If I do up my windows I can barley hear a thing from outside. Road noise is completly gone. I want to add even more under the headliner and the plastic trim pannel to stop interior rattles caused by my stereo.

So anyway what do you guys think would be the best thing the coating or b quiet or both?

[Lyle's GTP]

B quiet where you can use it. Then spray the coating where it's not practical to use b quiet.

makes sense, Thanks

Oh, one more thing. One thing that I find I have to do is put foam tape on the inside of interior panels where their is vibration. Also the push clips, and fasteners sometimes squeak and rattle, you might want to apply some silicone lubricant to those connections. Then make sure all you screws and bolts are tight.

This is definatily the most daunting part of building a good sound system.

All the panels are out of my trunk I have a custom install stereo. The trunk lid, quaters and bumper are the real problem. I m trying to do a custom 6x9 deck cuz in order to get a kick fit box we stuffed it way back causing me to mount my 6x9s higher. It's a really cool setup hope I get digital pics of it soon
