I don't know anything about polarity. Would the fact that it's all running at 4 ohm and the speakers are 2.7 have to do with anything? The guys doing the install aren't total noobs. I'm just trying to figure out the reason why. Again, sounds fine on most songs. Tweeters are amazing. Woofers just get rowdy sometimes. Well I plan on getting to the bottom of it tomorrow so I'll keep you guys posted!

No. The resistance in ohms you are running is dictated by the speakers (or load on the amplifier). Your set being 2.7 ohms will give you a slight increase in output, and a slightly bigger draw on your amp, but not enough to cause the amp stress.
it sounds to me like they hooked the tweeters to the crossover (or they would have fried by now) but bypassed the crossover and ran straight from amp to the woofers. Without a high pass filter on the amp (or without it on and set to a high enough frequency) your poor little woofers may be seeing down to 20HZ. Alot of music out there wont reach that low, so you only distort, or get sloppy on certain tracks.
Let us know what comes of it.

Correct polarity means that they hooked up the negative terminals to the negative outputs and positive to positive. If one of them gets reversed (positive to negative) you can get the popping sound you describe.
