what would give them plenty of power under 200 dollars?

what is the difference between 2 ohms and 4, and what does bridging it do?

also what are some good speakers with good mids and highs so you can hear the music over the subs?

Answer 1

A good amp would be one that matches the sum of the RMS power handling of both subs.

Ohms is the electricla measurement of resistance. The closer you get to 0 ohms, the closer to a dead short the load is to the amp. This makes the amp push more power with more heat. Some amps are designed to handle loads down to 2 or 1 ohm but 4 ohm is better for sound quality.
