I used Great Stuff on my trunk lid. The can said on it "for gaps and cracks". I didn't have any issues, I started out with a little and a few hours later once it was set up I added more to the places that needed it. It worked out pretty well on my car. Just get regular Great Stuff spray foam and not that 3X expanding stuff. IMO works much better.

If everything was working correctly before the battery change then its defiantly the battery. Double check the connections and make sure Its fully charged.

Thanks for the responses Matt-h, I might have to do that. The only thing im worried about is a to specs box is a min of 1 foot cube, but im wanting to port the box and min for that is 1.75. that wouldn't give me a lot of space to just put a box in and move it around and decide. I would like to build a box up by the cab under the deck port with the box port aimed through the deck port but im not 100% positive on how to do that. I will have to do some in depth research.

I'm wanting to build a custom box or boxes that will allow me to still keep my spare in the trunk. I have the stuff to build the boxes just wanted to get some advise before I just went balls out. I keeping with my small amp and 2nd battery for now. Waiting on funds to up grade those.

1st build, Needing some help and Ideas!! I am getting ready to start building some boxes for my 2 Kicker CVR 12's. Im having an issue trying to decide how exactly to build my boxes. I have a 1994 Buick Roadmaster Limited (so massive trunk space) and the rear deck is ported. I am keeping my spare tire in the trunk (I am one of those guys who has to have the spare and a small set of tools in the car at all times) Here's What i have now: This is what i have to work with: Here was my plan: Any ideas and help would be greatly appreciated Thanks
