tbh, i would love to hear this system play! the vids doo seem pretty epic! and some kind of deadning looks like a MUST!
my VT kit liked to fall off when playing the lows.
ive found that some sound deadning has been pretty shit tbh!
and Expanding Foam, and loft insulation works alot better and a fraction of the price!
fill the boot lid from the bottom and holes in the top! make sure you work it all the way around, let it set for a few days then continue to fill! till its buldging out!
rear quaters, take the cards off and pack it with insulation OR carrier bags then fill the bags with foam!
under the bench, i filled mine with loft stuff again! so when i put on a false floor it sat level!
you will notice a vast difference!
no wall install it
make some kind of tunnel! 3 / 4 either side
