Audio Systems: 2001 vw jetta monsoon deck, interface plugs, vw jetta

Question
I would like to hook up a after market amp to a monsoon deck that comes stock in a vr6 vw jetta 2001.  But there are no rca jacks on the back of the deck and there is no high input jacks on the amp.  is there any way to hook an amp to this model monsoon deck?

Answer
you need a hi/low interface for the monsson system they interface plugs behind the speakers or behind the factory radio  vr6 comes with the speakers in the doors not in the rear deck so it is beter to plug behind the radio
also theoutput is full range
you can buy the interface from www.oemautosound.com
