well.... then..... If you are going to run two 12" car subs off a plate amp there is something you need to consider, speaker impedance. Most car subs are 4 ohm impedance, but some are 2, 8, 6, or even dual voice coil models which have two impedance values. It should say, "4 ohm" or something similar on the magnet of the woofer. Lets assume they are both 4 ohm subs- you can either wire them in series for an 8 ohm load, or in parallelfor a 2 ohm load. Those are your options for wiring 2 subs to a single channel plate amp. Most home audio amps are rated at 8 ohms, so the 8 ohm in series example would work, but a 500 watt rms amp would only give 250 watts to each sub, power is split equally. A 2 channel amp rated for 4 ohm operation would also work, I just thought you should keep this in mind when selecting an amplifier.
