Awesome, thanks a lot for all the input.
They're in 4.5 cf net EACH, so shouldn't be a problem there, saw polecat recommend that size to someone a few weeks ago, so that's why i went 4.5. I 'remembered' hearing 42hz was good, but it was just a mixup between the 12's and the 15's, oh well.
Alright, so right now it's looking like my best options are 33 or 35hz.
Oh, and right now i've got a hifonics bxi2006d hooked up to them. I realize it's not quite enough power for them, but first i need to get my electrical upgraded, which will hopefully be happening in the next few weeks, then i can see what i'm REALLY working with, before i decide if i need a bigger amp.
Again, i really appreciate the help. I was really getting frustrated with all the less-than-knowledgable sound shops around here, and this box WAS acceptable until a few days ago, but i found out on wednesday that my drivers side front midrange speaker was wired in reverse phasing, which was cancelling out my entire system, and now that i have plenty of midbass, this box is not only extremely peaky, and fairly low-output for a 15, the midrange frequencies are really crowded with the subwoofer constantly trying to play the same notes as my midrange speaks, even with the crossovers //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
