Mack187Murder Posted July 13, 2017 Report Share Posted July 13, 2017 So my doors are damped inside and sealed and damped again. Front and back. How important is it to do the roof. I'm guessing I maybe should with a sub on a 4.5 k amp? Also my vent will be facing upwards. And I kind of ran out of dampener in the back cabin of my truck. So I got the back wall covered. By the back pillars I just have square chunks here and there and same with the floor just to get rid of the hollow sound. I think I read somewhere every surface doesn't have to be covered to work properly. U can put sheets here and there. Just wondering if there's any truth to that. .

Ryan Turner Posted July 13, 2017 Report Share Posted July 13, 2017 Usually need about 1/4 coverage per panel, for roofs I usually find the middle between bracing points and smack a sheet or half a sheet there . if it's a massive panel (entire side to side of the vehicle with no real bracing or bends) cut a sheet into 1/3rds do one middle and one on each side. That's how I've always done it atleast Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted July 13, 2017 Report Share Posted July 13, 2017 Therea truth to it, at a certain point you're nust wasting money because adding more will not gain you any benefit. Testing will be able to tell you what the point is for you You may want to consider bracing the roof as well. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Second Skin Posted July 13, 2017 Report Share Posted July 13, 2017 The testing behind vibration layer control says that 60% coverage will yield 95% effectiveness. On general daily drivers with no bass and no big engine some people drop down to 40% or less coverage. But for vehicles with bass and added engine power you should stay up in the 60% coverage range. The problem with scaling back and choosing where to apply product and where to skip product is that it is an educated guessing game. You would want to start off by getting product on the large unsupported metal pieces. Then for the ceiling you would want to reinforce the spot welds of the roof, where the roof meats the braces with product on both the roof and the brace connecting. With the hassle it takes to remove a headliner, I would always recommend putting in enough products the first time, once, to avoid future removal of the headliner, wasting more time and money.

Broke_Audio_Addict Posted July 13, 2017 Report Share Posted July 13, 2017 You just missed a 20% off sale. Next one will probably be labor day.

I'm in Canada so shipping's a bitch If ur ordering multiple large products, i strongly suggest u call them and place ur order over the phone and see what they can work out on shipping. They help me ALOT with my order, i live in hawaii so it was rediculous for shipping when just using the site. So i talked to them directly and they were awesome about it and really helped me out. Granted i ordered about $1,000 worth of product. When u have multiple products, they can condense things into less boxes, saving on shipping. Not sure how much they can help if ur jist ordering one box of a single product. Wont hurt to ask tho. Link to comment Share on other sites More sharing options...
