I'd find the frequency you like the best for the components first, then what they are crossed at, put it the same for the sub so you don't lose frequencies.

bump william ,pls read my edited post about the pics u drew.

The first one would be a 2 ohm load in either the left or right rear channel, note: either. The amp is stable for 2 ohms in one or both left and right, just not bridged. The only thing is that you will lose any bass that is focused mainly in the opposite channel, unless you can have the rears in mono.

so the second pic, could u explain that one? eg. ohm load, output, mono? sorry for the questions, dont wanna blow up this stuff ive been waiting so long to have.
and also, if i hook the sub up on either the left or right rear channel, that would be 2ohm mono? what is the output on that?

On the second pic, for example, channel 3 is to one v.c. and channel 4 is on the other v.c. This way, each channel stays at 4 ohms and recieves 50rms? if thats what your amp is.

The second one would be easiest on the amp; each channel will be at 4 ohms (basically, what each voice coil is individually). The only thing is that it has to be in mono, otherwise you could destroy the sub. Think of the dual voice coils as left and right of the sub; if you have bass coming only through the right channel in one part of the song... uh oh... one side of the sub is working -internal damage awaits. heh

That would be 50 rms x2 so 100 total to the sub.
and to reiterate, the 2nd pic has to be in mono! :)

You said that the amp puts out a different amount of power at 2 ohms (than if you doubled 4 ohms) right? -if I read correctly from one of your older threads
It should be twice what the output at 4 ohms is usually; say 4 ohms is 50 rms per channel, then 2 ohms will be 100 rms per channel.

yea, im not sure about that william. i tried emailing eclipse about the actual numbers in each ch mode but never got a response back. the manual says 140x2 @ 4ohm.
so if i go with pic 2, the sub will be running at 4ohm, in which each vc is connected to a channel.. but the amp needs to be able to be run in mono for this, correct? is there a way to check this? lol. is it common for this to be possible?
