Default need expert advice.

is there any way i can check how many ohms/rms wattage my amplifier is pushing to my subwoofer? i wired it DVC to 2 ohms (600w RMS x 2) but the thing is, it's sounds weird; like my i wired the incorrectly.

You probably wired one of the coils out of phase. Try switching around one set of wires.

Use an ohm meter... disconnect the sub leads from the subs and measure the resistance with a multi meter. This will also confirm the phase is correct. Electricity takes the path of least resistance so if you wire it 2 ohm, your amp will run at 2 ohm (or clip and shut off).

It sounds like one or more of your voice coils is out of phase, and that needs to be corrected post haste.

If both coils were out of phase with the source they would be in phase with each other.

Your sub is a DVC 4 ohm sub and 450 watts RMS, continues and 900 watt max.
I would wire the VCs on the sub in parallel for a 2 ohm load, that way you have 600 watts of RMS power out of the amp, better to be overpowered then underpowered.
