angled stuff i did already. this week i will make a couple more box's to test fiberglass resin. another thing i will post when i get them is results on sanding ports. of course this will be different for ever box but i am going to find out what kind of increase in db's it can get.

one thing i have noticed. i am like 4-5db's quieter in 18 degrees than like 70. and its only going to get colder.

Resin will probably not make much of a difference.

I've found that my truck likes to be somewhat cool. My scores have been around a db louder on 60 degree days compared to something in the 90+ range. You're crazy for testing when it's 18 degrees lol. Find a building and some heat.

i heard resin is .5 but i gotta find out for myself. everything people have said i am kinda checking. it was 18 tonight in my garage and its only going to get colder. i have a lot more testing to do before i am ready for spring break nationals, so i have to keep being cold.

Try single vs. double baffle

you should try single baffle with dowel bracing VS double baffle with no bracing (ie, is it a better idea to double baffle, or just use a single baffle with dowel braces. i have heard people claim single baffle with dowels is more effective than just using a straight double baffle.)

thats, if you didnt brace in the last test lol
