i need wiring diagrams for the premium sound system

i need to find a wiring diagram for a 07 vw jetta 2.5 with premium sound system. i bought a subwoofer and amp to put in and i need to splice into the rear woofers to install with stock radio.

get me the vin # as the wiring is built per car and i can get you it a lot better.

dont need to do it by your deck but get a 2 channel peripheral theyr like 20 bucks at frys and splice it into your rear speaker lines right at the speakers it will give you rca output from your rear channel and still allow your rear speakers to work as well as you dont even have to pull out the stereo and it will clean up the signal before it hits the amp

On a 07 Car you can not splice in a harness the way you can with older cars the systen is alwats testing every thing looking for low and high resitance.
plus ther radio is amplified and the signals to rear spearkers come from the amp taping into wires will shut the channels of in that amp.
