Rob...let me know what you think.
I'll probably go with the MDF for the box. I have 2 10" JL audio subs and a MB Quart mids and tweets. I also have the kickpanel that will have an MB as well as the bottom of my door. Now the box that I was going to make was going to extend through the length of the wheel well. I was thinking about mounting the amps on one side of the panel box and the other was just going to have speakers. I know this doesn't make sense, but I'll try to draw it up so it makes more sense and post it. DISCLAIMER: I'm not the best artist so PLEASE bare with me.
