my buddies is goin in a 99 jeep grand cheeroke....and ya ur right there isn't much space to work with, i might have to go with aero ports.

ight cool....im starting to look into sketchup and stuff and all i really needed help with was port calculations, im new to that and needa learn better. thanks

I recently just ordered me two 18" fi btl fully loaded and im selling my 18" q's to my buddy. What I need is a good box design for my btl's. My maximum measurements for the btl's box is 49"x20"x29". i currently have aero ports for my q's and im wanting to do a single chamber with a big slot port, subs up port back. And i also need a box design for my buddys setup, max measurements of 40"x26"x26", with the same idea as my box. so if there is anyone with ideas, let me know please. thanks

im about to switch to port tubes instead of slot ports and i was wondering if i have 2 18" fi q's how many 6" diameter ports would i need. i have the box set up into two chambers at 7.1 cubes each. i was wanting to tune the box around 31-33 hz. i didn't know if i should use 2 ports per chamber or just one and what the exact lengthe should be.....ive used most calculators and they are telling me with 1 6" port in a 7.1 cube box the length should only have to be 6 inches, which doesnt seem right b/c i was thinkin more like 15-16 inches. shoot me some info thanks

oh and as of now im only runnin like 650w to each sub....but it will be 1000 to each once i decide to drop money on a new amp.

yes i checked for tensil slap but it sounds more like its something to do with the voice coils, like an enternal popping. and ill try emailin nick....thanks

does anyone know a phone number or something to contact fi about a question? ive tried emailing and it didn't work, they ignored me. i ordered a fi q 18" about a month and half ago and i noticed it had a black basket instead of gray, then i ordered another one a couple weeks ago and it had the gray basket and many differences. and just over a week of having the newest one, there is a popping noise coming from the sub as if its starting to go bad already. any comments just let me know....thanks.

i am new to FI audio and ive been searching and watching videos. i have become very interested in this brand now. i want to probably just get one of the new 18" btl's and i didn't know what options to get for this sub. it will be used daily but i still want to know how many db's this thing will put out with just having one of them. and also what is the best amp for one? thanks
