I connected a set of Kenwood 4 inch speakers up to the old Clarion and it did just fine. I eventually replaced it with a CD player though....but not because it broke.
Your wording is a little odd in explaining resisitance. The higher the number the higher the resistance. In other words, a higher numeric value means that device restricts the flow of power more. Think of a valve in a water pipe. When the valve is opened a slight bit, it has a high resisitance to the water, and only a little bit flows. When the valve is opened all the way, it allows a large amount of water to flow, and thus poses very little resistance to the water. A lower resistance means more power will flow, since there is less restriction to it. A 4 ohm speaker will allow more electricity through it than an 8 ohm speaker, and thus the amplifier will work harder to provide that power.
Electricity is a lot like indoor plumbing. The biggest way to think of the amplifier is that it's a valve, not a power source (that's the battery). What happens is that the amplifier, or "valve" in this case switches on and off rapidly sending pulses of power to the speaker. Those pulses correspond with the music you are listening to. When the pulses reach the speaker, they energize an elecromagnet in it, which attracts it to the permanant magnet in the speaker, and thus makes it vibrate to the beat of your tunes! Your speakers are sort of like those water saver washers in a faucet in the fact they offer resistance to the flow of power.
The problem comes if that speaker doesn't hold enough power back, the amplifier "valve" can only flow but so much power before it could get damaged. If a speaker lead touches ground (equivalent to a pipe break), or if the speaker does not restrict the flow of power enough, too much power flows through the amplifier and it will get hot and burn out...sort of like if you leave the faucet running and the sink fills with water and runs over!
