nope its pretty simple you just want to seal it (all corners inside) with silicone and i might suggest using 1" mdf to reduce flex andget spray on dynamat for the inside...goop on sound deading works better but costs 50 bucks and is messy. also if you are not into covering but are good with wood and your trunk is gray...........fleck stone makes a different covering material it sprays on..some say its tacky but so is fuzzy carpet lol i am using the fuzz on the rear of my sidekick dont read too much into what i say about insults either its more of a funny jab than a shot at anyone directly....i used **** to suggest it is easy....the complexity is of your own willingness to do
