wiring 2 bd 1000's to a 18" Fi btl

[shane27 0]

I am wondering how to go about wiring 2 older fin style rf bd 1000.1 amps to a single 18" old 3 stack Fi btl. The sub needs a recone so I could get dual 2 or 1 ohm coils.both the amps have the spot for the sync cord.the real question I have is one amp to each coil @ 2 ohm? or get the dual 1 ohm coils and run both amps in parallel to both coils in parallel? I never used the bd sync cord, don't know if I should trust it? I don't want one workin harder than the other.as u guys know I'm looking for a 2 ohm load on these amps. Thanks a ton for any input!!!
