4 Ohm Speakers Problem

You can use resistors, but it will defeat the purpose. If you put a resistor in, then the amp will feed just as much power into the resistor as the speaker. Here's an example using a 4-channel amp... @ 4ohms an amp pushs 100watts RMS per channel (remember this is just an example). @ 2ohms it pushes 200 watts RMS per channel. If you hook up one 4ohm speaker to each channel, then each speaker will receive 100 watts. If you hook up one 2ohm speaker to each channel then each speaker will receive 200 watts. Now, if you hook up two 4ohm speakers to each channel (giving you a 2ohm total load per channel) then the amp still pushes 200 watts to each channel, but each speaker only gets 100 watts (200 watts/channel with 2 speakers on each channel gives each speaker 100 watts). The same thing will happen if you put in a resistor. The amp will see a 2ohm load on the channel, and push the 200 watts, but the resistor and speaker will each receive 100 watts. So you would get the same result if you just stayed at 4ohms and 1 speaker per channel. I'd suggest getting a stronger amp, or if you want to get creative... Look Here.
