SnowDrifter Posted October 4, 2011 Report Share Posted October 4, 2011 I'm looking for some good but cheap sound deadener to spray on the inside of my upcoming box build to eliminate any echoes / resonating anything from it. The places I have available to me are Napa, O'Reilly, Home Depot, and Lowes. So if I can get it at one of those places, it would be awesome.

teardrop Posted October 4, 2011 Report Share Posted October 4, 2011 (edited) a good bed liner is good for the outside not inside because it ant smooth Edited October 4, 2011 by teardrop Quote Link to comment Share on other sites More sharing options...
spldreams Posted October 4, 2011 Report Share Posted October 4, 2011 second skin makes a spray on deadener but its not meant for inside of boxes. you should really have to spray anything inside a box to stop echoing. as long as you build it solid with 3/4 mdf or birch you should be fine Quote Link to comment Share on other sites More sharing options...
bassrace Posted October 4, 2011 Report Share Posted October 4, 2011 (edited) I've used undercoating/bed liner like rust olem brand. Its for rust, sound deadening, underbody coating, ect. I only used it in areas that were hard to get to and wheel wells though, not a box.

SnowDrifter Posted October 4, 2011 Author Report Share Posted October 4, 2011 I got the idea from seeing somebody put sound deadening on the inside of their port for sound quality. I am trying to do that to my box, but have a bunch of bracing that would make it a PITA to do with sheets.

heckvr4 Posted October 4, 2011 Report Share Posted October 4, 2011 i have always wanted to add deadener inside my box too, just to see if it makes a diff on the termlab. technically it should make the box a lil stronger rite ?...

STScolorado Posted October 4, 2011 Report Share Posted October 4, 2011 i put roll on bedliner in a box before for fun and it dident help me on the termlab at all might want to just pour a shit load of resin in the inside of your box it will help strengthen up your box and give you a smooth inside for your box for air to travel out your port smoothly therefor giving you better sound quality from your box. just my idea Quote Link to comment Share on other sites More sharing options...
Second Skin Rep Jon Posted October 4, 2011 Report Share Posted October 4, 2011 I agree with most everyone here, applying any sound deadening inside really isn't going to help. Sound deadening = for sheet metal, not MDF, ply, etc.. Quote Have a question about Second Skin? E-Mail me! Link to comment Share on other sites More sharing options...
xballking21 Posted October 4, 2011 Report Share Posted October 4, 2011 i wouldnt put anything inside the box maybe sand it down with some high grit sandpaper other wise nothing Quote #winning 2 DC AUDIO XL 12s 2 hifionics 2600 2 Deka yellow tops big 3 everything you need to know about car audio...

spldreams Posted October 4, 2011 Report Share Posted October 4, 2011 the only thing you can probably do if you really want to is fiberglass the inside of the box and sand it smooth. this wont necessarily help or hurt performance in my opinion but it can help air flow more easily in the box. personally I wouldn't worry about it Quote Link to comment Share on other sites More sharing options...
