help with sda identification and amp

[cluelessinwisco]

I have a pair of sda's which I belive are the 2's. 3, 6" mids and 2 tweeters + passive radiator in each. The interconnect cable seems to have 2 round pins + an alinment pin. this confuses me because a tech at polk offered only a two blade or a blade and a pin configuration. I need to identify these so I can get some specs to give to LUMINOUS AUDIO TECHNOLOGY to set up a really sweat passive pre-amp for me. I plan to use a carver m1.5 amp (by the way any one know this amps input imp. and input sensitivity?) don't know how the passive pre will sound but I keep the tone bypassed on my nakimichi av-500 reciver.

p.s. any thoughts on a sub?
