Hello, I am strongly considering getting some FI BLs. First, i have to say that i am very impressed with the videos I have seen of what these subs can do. I have not heard any in person, but i also hear the Sound quality is amazing.

I have a good understanding of car audio and installs, im no expert. Here is some questions i have:

looking at the FI BL 12"

"Re: 0.75 Ohms/coil | 1.5 Ohms/coil" what is this? i thought the D1 and d2 options where ohms loads per voice coil? I have made one slight mistake on an ohm load and fried a very good sub, cause my calculations were less then 1/2ohm off.

If i buy 2 FI BL 12"s can I safely run a D2 off a single channel amp? Running in parrallel would have to run at 0.5ohms?

I listen to Hip hop/R&b and rap, what would give me the louder, bass for all sorts of music, either 2 BL 12"s or a single BL 15". I have 2 kicker 15" L7s and they sound great for the low deep bass, but sound like crap for anything else.

Right now i am running a MA Audio HK802SX amp....any other recommendations??

Also what exactly are some of the options?

-extreme lead

-universal

-flatwind

Wiring parallel will have a final impedance of 1 Ohm on the D2s so it will be good for a mono block @1 Ohm. These subs will sound insanely better than the kickers IMO. just make a good enclosure.

Welcome to SSA, you'll need to familiarize yourself with the BL FAQ located here

Also, check out this thread on impedance rise.

Thank you, i was looking for a detailed info sheet on the BLs, with recommended box and port sizes.

and thank you Jason907. But i know how to wire one driver with d2 down to 1 ohm, i was asking about TWO subs

just found this at fosgate.. what is with the "Re: 0.75 Ohms/coil | 1.5 Ohms/coil" just curious if i wire TWO 12" BLs in this way, that i wont kill them..

That is the DCR Resistance with the coil at rest. You don't need to worry about it.

Outstanding, thank you

John's pretty much covered all the important things. the12volt . com also has a nice VC wiring section.
