Hello rattle822,
A pair of JH4512-04's can be wired to 2 ohms if the subs themselves are paralleled. There's only one voice coil and it's 4 ohm. If wired in series, the final impedance to the amp would be 8 ohms. They cannot be wired to 1 ohm.
In bridged mode, your 4-channel amp is only stable down to 4 ohms. You can bridge 2 of the channels to provide a relatively low 200 watts RMS X 2. The best power solution for your subs would be to bridge channels 1 and 2 and wire one sub to it. Likewise, bridge channels 3 and 4 and connect the other sub. If you connect both subs in parallel, the impedance will be too low causing the amp to overheat and possible fail.
As for the settings: Low pass filter on, crossover somewhere between 80-100, input levels to match your receiver, and bass boost to your personal preference.
Hope this helps.
