Ohm Loads For Monsoon 6x9s

I am trying to figure out the ohm loads on my 01 Alero witht eh Monsoon Stereo can anyone help me

The tweeters in the front doors and in rear 6x9s are run at an impedance of 4Ω, as are the midranges in the front doors. The woofers in the rear 6x9s have a resistance of 2Ω.

So yes, in effect the speakers in your rear deck have two different resistances.

So then I could run my aftermarket 6x9's on the 4 ohm load then since that is what the factories tweets run
