I have a 2 channel pioneer gm-3100t 300watt rms amp and i also have a 500 watt rms 4 channel sony xplode (i know *yuck*) anyways my question is how could i go about wiring two of these up so that my 2 JL 12w4's are running on the pioneer amp and the speakers are running off the 4 channel, i know the theory of how to do it but it wont work, please help.

I'm not sure what you are looking for . . .

Are you asking about power distribution blocks?
Are you asking about RCA/Signal feed?
Are you asking about speaker load/impedance?

What theory do you know that doesn't work?

The combination of amps that you have will work for what you want them to do. (Although, if your subs are 4 ohm SVC, you might consider a mono amp to milk it for maximum power - but the 2 channel will work well and stay cool).

Where exactly do you need help?

Sorry i didnt specify, im trying to get the hooked up with the RCA feed's, the Signal feed and i already have a power distribution block to feed both power lines and both ground lines. I know i should be getting a monoblock amp but this is what im working with till a few weeks when i get my new MTX 4 channel and monoblock amp's. The problem with the RCA feeds is that on the back of my HU there is only a rear + and - out, a front + and - out and an input + and - and iv read somewhere that the input was for the XM ready capabilities with another sony adaptor but i could be wrong, the model of my headunit is a Sony CDX-R3310 i havent had much luck finding out info about it, only the 3300 model and that has lesser capabilities.

???

I'm not understanding. RCA's aren't labelled as + and -. They are Left and right. A single RCA connection has the + and - built into the connection point (the centre is + and the exterior is -).

Are you assuming that the colours red and black mean positive and negative? That is typcially the case in car audio, but for the RCA connections red is "right" and black/white is "left." It sounds like you have found everything you need. Now you just need to plug and play with the amp.

Your CD player has RCAs for Front L/R and Rear L/R. The rear can act either as rear speakers or a sub output - not both at the same time. So you will have to choose what you will do with the rear. Will the rear feed the 4 channel amp for your back speakers? If so, then you can also create a patch for it to go to your sub amp from their. But you will not be able to control the sub amp independantly of the rears.
Another option is to run the rears off the same RCAs as the front. Then you will have independant sub control on the rear.

Is this the direction your question was going?
It sounds like you understand the power, ground and remote wires. Where have you connected your remote wires for the amps?
