Fi Subs Bl series

[Generation X 1]

Will four eD nine.1s amps be enough power to push 4 BL 18s.

Btw what is the minimum air space required ported per sub?

Those amps will work fine.

I personally would not do an 18 in less than 6 cuft. You can get away with 5 cuft. . .

If your going to run four of them amps make sure you get dual 2 ohm coils..

Is that 6 cubes gross vol. or net?

Can someone please give me specs on a box for a BL18

please include measuremets and port displacement, ideal airspace 6cf. tuning 33hz or lower.

fi recommends 5-10ft^3. go somewhere in there. tuning will depend on what you want out of it. port displacement cant be figured out w/o tuning, box size, or port area...so go figure those out first.

how much space do you have/are willing to give up?
