I was thinking of adding some sub woofers to my car and building my own sealed box from scratch. Any tips on what to use as far as materials? At the moment I plan to use MDF board and seal it thoroughly with liquid nails and silicone. I also plan to add weatherstripping under the mounting part of the sub for a good seal there. If anyone has any other tips to help with this project I would love to hear them.

If you're not worried about moisture, then MDF is fine. But if the trunk isn't sealed real well, if there is even just a little bit of moisture that seeps in, use baltic birch plywood instead.

Living in a country with temperatures from -30 Celsius in the winter, tp +30 Celsius in the summer, and since i have mostly been driving 20 year or older cars, i know all about moisture in the trunk.
My method are either to use waterproof fibreboard (bathroom flooring) or if using MDF to paint all surfaces. (outside and inside) with thinned PVA glue before applying any carpetry.
22mm Water resist fibreboard
carpeted and completed.
