The big 3 is upgrading the following wires with the biggest you can possibly use; 1) alternator positive to battery positive, 2) battery negative to chassis, and 3) engine ground to chassis. Some people replace the factory wiring; others add additional cables to the factory wiring.

Interesting on the ohm meter -- I am guessing based on other readings I took around the car, that my meter is not uber accurate and/or needs a new battery.

Thanks on the Big 3 definition. I may use some leftover wire to further ground the chasis. Thanks again for your help...I sure hope the system sounds good...

Here is what I have going in:

Memphis Audio 5 channel Amp
Memphis Audio 6.5 comps up front
Memphis Audio 6.5 comps on back shelf
Memphis Audio 12" sub (may change to an 8" )
edead80 sound deadening
