I'm putting new speakers in my 97 Astro front speakers 6.5" 4ohm 75W RMS. Rear is where I have questions the rear doors get 6.5" 4 ohm 75W RMS, the pillars get 4" 4ohm 20W RMS. The factory wiring on doors & pillars is paralleled. The amp is 4 channel 100W at 2 ohm or 50W at 4ohm.
Is there a way I can connect them it so I won't blow the pillar speakers?

Bridge the 2 fronts and the 2 rear on 2 channels and then bridge the other 2 off the other 2 channels, tune gains accordingly and woala.

The front speakers will get 50w at 4 ohms each, and the rear speakers will get 100w at 2 ohms (so 50w each) - turn the gain on the rear channels down so that you're only putting out around 50w to avoid blowing the speakers. You can also get speakers with more power handling for the pillars

Bridging an amp at 2 ohms is a good way to blow it up. Don't listen to this guy. Voila.

You can't just turn the gain knob to adjust power. 1/4 turn don't mean 1/4 power.

Okay, I was reading at Gain Settings (http://www.thesuicidaleggroll.com/gain.htm) on how to set the gain
