new to soundeadening..need info

[GSweetZ]

i just recieved my 50 ft roll of b-quiet extreme... and basically im wanting to sound deaden my sedan..

just wondering what portions i should pay more attention too.. i know for the front doors all the metal should be done.. should i also try getting the outer door skin as well? how about the back of the interior door panel?

should i even bother with deadening my rear doors i dont have any speakers in there..

the rear deck is a sure deal to deaden.... and all of the metal in the trunk.. but how do i go about doing something with my rear bumper.. they rattle like crazy as it is.. or is it something behind the bumper?

im pretty new to this stuff.. but id like to do it right.. and is my 50sq ft going to be enough for my trunk and front doors?

Are you deading for road noise or audio?

audio...

Well, first off if you have subs in the trunk, I'd line the trunk lid to stop any unwanted vibrations there. Then I'd pay attention to the doors the most. If you can put more than one layer, that'd be good. Once you remove your door panel, put a layer on the plastic itself if possible, then another layer on the actual metal. I'd do that only if you have enough mat. If not, just put it on the metal part. Try ebay for some stuff called FatMat. 100 sq ft for 100 bucks, not too shabby. Works well. To keep out road noise, you can remove your seats and carpet and line your floor. Keeps a lot of road and exhaust noise out of your cabin. But overall, I'd line all my doors and trunk if possible to get the most out of the audio.

loading up panels with sound deading will only get you partly there. Use your sub to find rattles and use foam weather stripping tape and whatever else you can to stop the vibrations.

Okay, I just finished sound deadening my P5 yesterday. Sorry it's not a sedan but i noticed the most noise comes from the rear wheel wells and the doors. I drove it completely stripped so that I could pinpoint the noises. I used Raam mat V3 and that stuff is amazing! It sticks to anything including fingers! After that, I used 3/8" dual sided sound insulation from dragracing.com and placed that over all the floorboard and sticky-sprayed to the rear wells. OMG, it made such an improvement. Now, no matter what speed I drive, I only hear low-pitch noise like from the engine, the sound insulation really works to kill high-pitched sounds from concrete roads. Downside is, I'm driving a lot faster!
