need help wiring jl cleansweep cl144 to 99' jeep grand cherokee limited stock amp

as the title indicates, im having the hardest time finding a good set of instructions for wiring my cl144 cleansweep to my 99 jeep grand cherokee stock infinity amp. Also when i do find the correct wires to match up, how do i splice into them without cutting off the signal from the amp to the speakers? Advice would be very much appreciated.

You may need a signal summing device.I would locate and identifiy each speaker wire.Determine polarity then cut and splice the wires to the clean sweep.Then route the wires from the clean sweep to the other side of the cut wires leading to the amp.
