how much to use??

Hi everyone

I just bought 2 12" rl-p's and have a question about a box. My friend made a box that looks great for his two 12's but ended up selling the subs when he wreaked his car. The box is for 2 12's at 1.1 cuft. per chamber. Is this enough space for SQL? I plan on putting polyfill in the box but don't know how much to use. Any advice would be appreciated.

i filled mine up to about 1 inch away from where my subs baskets would end up for my 1.65 cube boxes for each of my 12's (4)

they sound pretty **** good... thats what i read to do for em on another forum...

i tried packing it tight.. and the sound got really controlled for super fast stuff, but it sounded almost underwater.. so i took

some out, like i said before 1 inch away from the basket.. and it sounds best like that, for me.

good luck, post pics : )
