I am planning on bridging 2 15 inch subs onto one amp and I was just wondering if I needed anything other than the basics to do that. For instance, do I need extra wiring kits, wires, a certain amp, etc.

Not with any modern amp. It's just a difference in how the wires connect. In some old school amps, you needed bridging modules, but this isn't done anymore.

What is the impedance of the 15s? Single or dual voice coil? What kind of 2 channel amp is it?

Wire the voice coils of the subs in series to make each an 8 ohm driver then parallel the 2 drivers at the bridge terminals of the amp for a 4 ohm mono load.
