banginAltima Posted April 10, 2009 Report Share Posted April 10, 2009 I have always been worried about losing db's by adding sound deadening. Quote If you build it, db's will come...

ChampN252 Posted April 10, 2009 Report Share Posted April 10, 2009 If you had no deadening period, kinda like of explorer, you'd be too busy fighting road noise to enjoy your music. Do you know how annoying it to to hit a bump on the road and it sounds like all hell is coming thru?

Guest KyleCannon Posted April 10, 2009 Report Share Posted April 10, 2009 (edited) Doesnt sound deadening add DBs because it helps stop flexing? Edited April 10, 2009 by KyleCannon Quote Link to comment Share on other sites More sharing options...
Cr@sh Posted April 10, 2009 Report Share Posted April 10, 2009 I would say it has more to do with having a good foundation in which to create a great sounding system. No matter what your style or preference is, sql or spl. get in a car without sound deading at all, and get in one that does have it night and day difference. It's bonus that you get higher spl with it! Quote My old install at cardomain, never finished! Link to comment Share on other sites More sharing options...
cc_audio Posted April 10, 2009 Report Share Posted April 10, 2009 Dynamat F@(ked my car. Instead of flexing the whole trunk deck, it just sent all the force to my hinges. Lets just say they couldn't take it. Haha. Now my trunk really flexes. You know thats gotta be a DB loss. I've also had to reset my sunroof in its tracks about eight times. Before the dynamat, my spoiler mounts snapped several times, and had to be glued, and then replaced, and then custom made from metal. I would never skip on the dynamat or any sound dampening matarial. Single 12" Solo X and Memphis 4kw pushing 3500W did this. Also put a piece of rubber under my rearview mirror mounts (attaches to roof not windshield) and locktited all screws and bolts. The mirrors outside the car are useless when bassing, but the rearview is still useable. Quote It's all gone! The Celica Build Feedback If I buy something from you, DO NOT USE FEDEX!
