thats 3db doubles the volume in theory
dynamat is good but there are other ways to do the same thing that dynamat does
plus i'm not after spl i'm after a street bass monster
and to do what needs doing will be well over £100 probabably at least 4 times
i will be making mdf roof lining all the roof will then be filled with expanding foam as this is the place that will flex the most
and becouse it's walled the sound waves don't have chance to completely form in the area in front of the wall so sq isn't really gonna be a big thing but in theory if it's tuned low it should sound well especially with the equipment thats going in
don't worry it's bein done right i'v always wanted a wall but never had a second vehicle to do it with so i'm making sure this is done right first time
cheers though
