We have no way of knowing this bud... So you have two options, hooking them up...
Or you can use a DMM and set it to ohms, put it in the subwoofers if they read dual 2 or dual 4 ohm they are good.
As far as the amplifier you could hook it to a car battery, jump the remote wire to +12v and use RCA's to 3.5mm jack on a phone to see if it outputs to a set of speakers.
