blake1886 Posted November 15, 2016 Report Share Posted November 15, 2016 I have seen people sealing the holes with abs plastic, metal and other materials to really seal the door. Is the necessary or could I just trust the actually deadener itself to seal it?

bluethunder Posted November 15, 2016 Report Share Posted November 15, 2016 It's best to add some barrier for the deadener to stick to or else you will just have a sticky sheet of aluminum sealing the hole. Quote Link to comment Share on other sites More sharing options...
Pioneerchuck Posted November 16, 2016 Report Share Posted November 16, 2016 ABS plastic will shatter if you're putting out some serious air. If you have a daily system then plastic will work just fine. If not then a piece of steel is best, just bring it to a metal shop and have them cut the pieces you need and then bolt them in place.

If you cover those holes you are essentially creating an enclosure for your door speakers, which will create more mid bass, but also can create too much pressure build up. I think most of the installers I have seen use the Luxury Liner Pro to seal the holes, as the person above says, if you use the butyl you'll have sticky butyl over the hole with nothing for it to stick to and it could get pushed around a bit by the air pressure and touch something you don't want it touching so be careful with that. Here is a good video of Mark from Car Audio Fabrication using this type of method. CAF Increase Mid Bass Quote Whether you are restoring a classic muscle car, building an audio system monster, or trying to give yourself a bit of silent luxury on your daily commute, we have a product or combination of products that will help you achieve your goals while saving money and save time. Look around our site, educate yourself and make the choice that is right for you. Over built to over perform - because user error, bad batch, and faulty install are excuses that other companies use!
