which cabels do you mean...the audio plug-in cabels or the power wires? could you try running the cabels to the Xplod amp first? if that doesn't work then the only way to get full power to both amps would be a seperate set of cables for each amp. but if its the audio cables then you can buy an adapter that splices into the regular rear speakers and plugs into your Xplod amp. well if you could get a little more specific with which cables then i could probably help you out a lot more, i'll be checking back to see which cables you mean.
