Audio Systems: Infinity Gold System JEEP Grand Cherokee 2001, jeep grand cherokee, infinity gold

Question
Hi,
I have a INFINITY Gold System in my Grand Cherokee 2001. I replaced the Headunit. Now i want to replace the INFINITY Gold amplifier witha aftermarket amplifier and the factory speakers with aftermarket speakers but i want to keep the factory speaker wiring (i don't want to cut this one).
I wonder if you have know the 2 male connector Amp with cables (18 pin & 12 pin femel connector that you can see here  à http://www.wjjeeps.com/jlwiringinst3.jpg ) which are plug into the factory speaker wiring and factory amplifier wiring.
If you know this one, could you tell me where i could buy it on the web, please.
Awaiting your reply,
Best regards,
William  

Answer
that looks like a hand made  and don't exist

just pull the radio out and the amplifier under the seat cut the plugs and get a AA battery and test all the wires until you hear the speakers pop you need to find 8 speakers

tweeters pop only once you have to change the battery polarity to pop again
