which sub?

[jamie vandenh 10+ year member]

I am buying a Fi bl series (not btl) 18" subwoofer. i am using a rockford fosgate t100.1bd amplifier on it, in a ported box.

I was wondering if i should go with the dual1 or the dual2.

my friend told me to go with the dual2 but i was not sure why...

Can anyone explain to me why i should pick either one in great detail for someone who is a general beginner at this stuff?

dual 2 will allow you to be wired at 1 ohm which = 1000rms+
