bass hits harder with my trunk open! WHY???

yes that makes absolutely perfect sense. so I need to d a better job sealing it off from the back where I have my amp rack so there are no leaks. should I close off the front of my box as well with another piece of plywood or would that be worse

the reason it does that is because it is cancelling out (when your trunk is shut). Bass is firing forward, then some of it is leaking backward through your leaky rear deck and the openings around the box itself. It travels backwards, hits the back of the car and then comes forward again but now its playing bass 180deg out of phase..basically reverse (to make it easier to explain). When you play a sound, and the same sound exactly the opposite, you get cancellation and the bass is reduced. Sorta like hooking up two subwoofers up out of phase, you know what i'm talking about? Anyway, When you open the trunk, the leaky bass is going backwards, and out of the car instead of bouncing back into the cabin.

This is why a car with a box aimed backwards typically sounds better then aimed forward (non properly anyway). Because the bass rolls off of the woofer and goes directly into the cabin, you get no cancellation. For a forward firing box to work properly, it needs to be sealed off from the trunk so no bass goes backwards at all, giving it no chance to cancel out.

You should maybe build a new box, sealed or ported. Doesn't matter. But seal that one off from the trunk. Also seal all the holes in your rear deck. $100 says that's where your current leak is. Rear decks have a bunch of holes in them and I noticed your beauty panel looks to be in front of where the rear deck stops at the back window. Might wanna look into sealing off the rear deck completely and revisiting your beauty panel on your amp rack that "seals off" right now. That is if you don't wanna rebuild your box.

If you do redo your box. Leave your beauty panel. And seal your rear deck and seal the subs off firing forward.
