Fi Technical

Hi all, I'm new to the forum but been in audio for some time. I posted earlier about making the change to Fi and Sundown. Great product! This is the old system, it is 2 Gain Industries GP18DVC2 subs running off an old school Lanzar Opti 50C, stock electrical. The best part: This box will work perfectly with 2 BL 18's, space, port and all. <object width="425" height="344"><param name="movie" value=" name="allowFullScreen" value="true"></param><embed src=" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>

would a BL 15 be alright all the way up to 5 cubes of air space? i know fi recommends 4 for optimal, but im just curious if it still sounds how its supposed to up to 5 cubes.

So the single 4 ohm IB3 is 4 layer, and the single 2 ohm coil is 2 layer. I ordered a custom dual 2, will it be 2 or 4 layer? Or 8 Or 1

The trunk of my car( 1999 Pontiac Bonneville SSEI) has opening that connects the trunk with the inside cabin of the car. I was wondering if facing the port towards this opening instead of towards the rear of the car would increase SPL or hurt it. Will the air be pushed into the cabin of the car or will it just be trapped in the trunk bouncing around on it self. I will prob end up leaving a gap of about 3" - 5" between the enclosure and the actual opening because the trunk gets narrow towards the back. Would I have to place the port directly in front of the opening or would having the port on one side of the box facing the front of the car matter? Below is a pic of …

my cousin has two tc9 12" subs that are blown. We were wondering if we could order baskets for 15" SSD recones to fit on the magnets. As far as the mounting screws go, they should about all be the same mounting area, correct? Do you think this would work, right recone?

hi there just bought a fully loaded 15" btl. i used my original box that my audiopipe txxa-15bl was in. the box is 3.5"cu with 36 sq inches of port 2X18. the box is 3.5 before i put the btl in it so its actually less then that. i think the box is to small its in a 98 civic sedan. my wires are 4 guage i know i need to upgrade and a new battery and new alt. but was wondering if i could get a box design ffor maybe 4.5 or even 5 cubes design if anyone had it for this sub. another thing what is a good line driver.

I'm trying to order a bl 15 and everything goes smoothly until I hit pay now and it tells me there has been an error and to choose a different payment method. I have Discover card and have used it to purchase since I've tried purchasing from Fi and it works so I know it's not the card. I have E-mailed Fi twice since Saturday night and they still havent responded. I would like to order as soon as possible. I've seen on here that they are behind on orders right now or something, but it would be nice if they could reply to me. Maybe they'll see it on here and help me. Am I missing something that I need to order my sub? Any comments would help. Thanks
