Trunk subwoofer in my 2012 convertible
I just finished putting a sound deadening mat (GTMAT 110mil) in my trunk and under the rear seat in my 2012 convertible. I still have to do the side panels in the rear and maybe the doors if I have enough. I bought 75 sq ft and it seems to go pretty far. Anyway, I did the inner fenders in the trunk and the floor. Everything except the metal panel that the roof retracts into. (I figured the sound has to get into the interior somehow). So now the booming from the subwoofer is diminished but so is the total sound. Sounds silly for me to ask, but how can I get more bass into the interior? I hope someone doesn't say cut a hole in that panel. I would be afraid to compromise any structural integrity.
