Just wondering if anyone has any good ideas for porting the trunk area so i can get more sound from my sub, which is located in the trunk. I don't wanna roll around with the seat folded down all the time, so it looks like i need to do some cutting.

I was thinking about folding down the armrest in the backseat and cutting come holes so i have a port to the trunk to let in the bass... it might look ugly though. Another option is cutting some holes near the rear speakers, but i dont know how much sound will come through there. anyway, any ideas???
