Patience is the main thing needed..Im still working on mine slowly,as time permits me.SEAL THAT JOKER OFF,or its going to be a dented up ragged out POS.Double lined 3/4 all way around.Need to be set on what space you are willing to give up,as well as the subs you are going to use,amps,and stick with it.More than Likely in that vehicle..its not going to be cheap to deaden that roof,or sides,ect.My 4 XFL 12s are banging theyre azzes off enough that the neighbors two houses across from me windows vibrate..Thats with a ported chamber per sub,and two VFL 4480.1ds.The wall will have the 4 12s,with one 4480.1d per sub using the MaxxLink that I got from Mylows.Take your time,is all I can say.Dont rush any install ever.And park that joker in a garage!
