window down takes alot of loading off the woofers so you get good gains. when you have enough port boom it hurts your score to put the window down.. here's 410in^2 for ya
still dong some testing. gonna start now on the SPL portion of tuning. i figured out my daily tune. its gonna be 40 with 240in^2. port will be of course doubled up. adding the extra layer of the port isn't going to make a drastic difference so for now. its much easier to use the single layer and the L brackets as well as screwed into a subframe i made.
i cant do much now the red top is sitting low so until the x8800 comes in ill do some medium volume testing.. still gotta glass the sides but for now im taking a break on hte build. i'm hurting everywhere..
i do like seeing what other do. its interesting to see what results they get
