General Fi

I was wondering, I'm from Kuwait and i like to order a Fi BTL 15" subwoofer from their site.. How's my ordering system should be if they are asking for the state? I have a friend here working in an US army base he can provide me his address there so that i can order to the website.. the problem is the state what should i put there in the field?

if you are going to use 2 10" FI subs in 1 box with 1 port does the port still use 16 sq in per cf? or does it double to 32 sq in? what would be optimal for 2 10" BL's Also would 2 10" BL's @ 1500 rms each be louder than 1 10" BTL @ 3000 rms? Thank you! i am trying to get my research done before i purchase.

I know this is a car audio forum so please excuse the HT question. I tried to get an answer out on the main forum but I wasn't getting any responses. I've heard great things about Fi and want to get a pair of 18s for my HT setup. I was told over on the Cult that some tweaks can be made to make the drivers IB friendly. So, the question I have is, what diffence could I expect between the SSD series and the Q series? I expect it to be loud, but I'm looking to hit the bottom octave with some authority. Opinions?

Hi guys, Im looking into adding a sub to my 2008 altima (with Bose) Im not looking for anything extreme in RMS liike when I had my RE HC a few years back in my older car. The sub I am looking at is either a 10 or 12' X. I have to admit im confused with the BP option. How much RMS does this add to the sub? The amp I was considering was a Diamond 300.2 that I can get at a very good price. Can someone also recommend a box for this sub? Preferably ported and if someone can let me know how this sub compares to something like a Diamond D3. I know its a lot of questions, but I do appreciate any help I can get. Thanks!

Ok so as you can hopefully tell I have a Dodge Charger. I have some trunk room to work with. I have 2 12 inch fully loaded SSD's being built right now I just got my 1200d Sundown amp. I know Chargers have a pretty good alt but I will of course still do the big 3 and maybe another battery. I would just like to be around 13v or a little higher. I read on Fi's website; "Ported box we recommend using 1.8-2.5 cubic feet @ 33Hz (this is optimal in our eyes and to our ears, you can tune 31-35hz fine if you so please)" So is that easy? Should I just go with a 5 cuft box ported and tuned at 33Hz???? What do you guys recommend? Thanks!!!!!!!!

i wanna know how the havoc compares to the fi bl. i have the fi bl but im thinking of switching to the havoc. im not sure though because ive never heard the havoc but by reading the reviews its way better than the q. is it better than the bl? how so?
