6x9 at 2 ohm

I have 4 ohm 6x9 by pioneer would it damage them to run them at 2 ohm?

i'd be more concerned with damaging your amp or HU than the speaker.......Kevin Gerry

use a 2 channel amp that is 2 ohm stable on 4 6x9s each channel in parallel.

You'll be fine like that , i do it all the time, you wont hurt the speakers but the amp will warm up a little more

The 6X9's are still 4 ohm, and always will be 4 ohm no matter how many speakers you hook together....thus the first response from DYohn.  What you are doing is running the amp at 2 ohms.  There is a noticeable difference in quality at that ohm load when you are running full range speakers, and it's not for the better.  Another obstacle with this arrangement is your inability to attenuate the rear speakers...except by wiring 4ohm L-pads to them.  But until you can upgrade to a 4 channel amp, it is do-able. Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

they are for my girls car so it doesn't have to be perfect, if you know what I mean.

If it's "just" for bass, any quality loss is probably no big deal, and at 2 ohms, it should be louder than otherwise. If it's just for bass, if your amp has a low-pass filter, you might want to use it. Even full range, I'd try it and see! :-) From what I've heard in most people's stereos, it has to be pretty bad to be noticable. ;-)
