Trunk setup

Hey, I'm doin a trunk setup for my friends 82 Monte Carlo. It's gonna hold (4) 12" Infinitys, and 2 Infinity amps. I'm gonna make a framwork around all the inside walls of the trunk, then work from there. One area which concerned me was around the hinge for the trunk lid. I dont know how to go about framing around that. I was thinking fraem a rough area, and if it still shows, maybe use some vinyl like a boot around the hinge or sumthing along those lines. Any other suggestions would be great. Here's a pic of the setup i'm goin for. The red areas are the areas Im not sure about.

Sorry, the pic didn't work. Here's a link.

The two on the sides will be the same volume ( I'm hoping)..and the ones in the back will be the same volume. If I frame it properly, It should be the same. I'll use some packing styrofoam to measure how close they are..and if ones a bit bigger...just throw in some scrap wood to make up for the excess volume. Shouldn't be too bad. That's not my real concern.

Ya I was thinking of a horseshoe type of deal. I think that'd work. Maybe vinyl over that to give it a clean look?

Alpine guy, you seem like you've done this before...got any pics of a trunk setup with the hinges done?

You Can do like alpine guy said to do with the brushes. But incase you want more ideas to chose from here is one that i used on my buddies 98 honda civic that i fiberglassed completly 3 - 12'' alpine type r's.

What I done was made the box and where the hinges are I made a rectangle frame out of MDF (3'' X 8'') Or More Depending on how large the hinge is. Then go to a car parts (Auto Zone, Advance)place and get two shifter boots I just used the cheapest ones that they had. Streach the large end (bottom) around the rectangle frame and secure it in place with some staples then take the small end (Top) And run the frame through the shifter boot, then tie it off with the string on the boot makes a nice clean install. When The lid is open all you can see is the shifter boot when ever the trunck lid closes the hinge goes into the MDF frame.
