Put mic, say an SM57 on the center of front skin about 1 to 2 inches if you want to get the fundamental sound of the kick. If you want a little harmonics, move the mic towards the side inch by inch until you get the sound you want. Another mic, even a condenser, small diaphragm, can be placed on the batter side, towards the edge of the kick to get that high frequency thud effect can be used. You can cut on the LF so you would have more HF energy from the second mic. I suggest you separate the tracks for each so you can properly mix for the sound you want later on.
