Wiring AMP Outputs

[HorsiesInDaBack]

2004 Boxster S

5 channel AMP

Factory BOSE system with rear deck subs.

How would you wire this? Ignore the Blue pair as they are the rear tweeters i believe. Wire channel 1&2 to the dash, 3&4 to the doors, and the mono sub output to the large white and brown pair for the subs?

We recently purchased a 2003 BoxsterS with the Bose system. Previous owner installed a Kenwood deck and the rear speakers are not hooked up. The front door & dash speakers are not wired correctly either. I was curious if you were able to get your wiring issues sorted? I appreciate the wiring diagram you posted in the link. I purchased the Bentley Boxster Service Manual but I can not find the wiring diagram that you posted. Is there a way to use the factory amp? Thanks!!
