In my SUV, my far rear speakers are Infinity co-axials 3.5" 2Ohm rated at 25wrms and my rear door speakers are Infinity 6.5" 2Ohm rated at 60wrms. I wish to hook up my far rear speakers in parallel with the rear door speakers but the amp will not go down to 1Ohm per channel so I am wondering if could put a 10uF Bipolar Capacitor in line with the far rear speakers and then hook it up in parallel so the load is still 2Ohms and I know that the cap will cut off most of the bass but then again its only a 3.5" so mid and highs is okay from those ones...

A good idea or not? Thanks!

The amp will see a 1 ohm load at any frequency above the crossover point of the cap. It should not be a problem for the amp since there is not a lot of information above 8K. That is where the crossover point will be.   I think you would even be safe playing it dow to 2K, that would be a 40 Mic capacitor. Play the amp for a while and notice how hot it runs. Then connect the rears and notice if there is any substantial temperature increase.
