Doug,
You cannot use resistors alone to make a crossover or filter network. To do this requires a coil/transformer with its own impedance at certain frequencies. It can also be made with a capacitor, resistors and coil. This circuit has a 'time-constant' but I am getting off on a tangent and this is not helping you.
Designing a proper, efficient crossover network is beyond the scope of what we can do here or is it needed for what you are trying to accomplish.
Further, just to say and view it correctly, too low of an impedance or resistive load does not PUT heat into the amp. That will cause the output transistors in the amplifier to run beyond their design parameters and cause THEM to overheat.
As you probably know, you need to know the impedance or 'output' impedance the amplifier expects to see and configure your speaker system according to that.
By using various series or parallel or series/parallel combinations, you can come very close to what the amplifier wants.
If you will tell me what (0hms) speakers you want to install both in the front and the rear and the amplifier impedance, I will tell you the electrical configuration.

Well I always thought if you used speakers with to low resitance it put to much heat into the amp.
As far as adding speakers I figure in that case might just as well replace the stock speakers with after market 4 ohm.
I thought what you said about about the restance would be the case, I have used resistors before to filter frequency like a high pass low pass of an amp.
