Stereo experts: tweeter wiring for a 2000

[sanfelice]

Combo of aftermarket HU, two amps, and some stock speakers.

I cannot seem to get this correct. I have some Dynaudio tweets that I have installed* in the dash. However, the wiring for the right side tweet is messed up. The right tweeter only works if the balance is even; it will not work when the balance is switched to right side only.

My guess is the wiring is crossed up, but I have followed the stock wiring. The weird part of this is that the wires from the back of the tweets change in their jacket color at the rear of the HU. Somewhere along the way there is a junction box. So, following the color codes from the tweet back will not work.

Any more schematics people could throw my way? This would have been the Dolby Pro Logic/ SC-901 system.

Thanks

Greetings. I am not familiar with Dynaudio, but this seems to be definitely wiring related. You say the tweeter wiring is messed up. Did you use a aftermarket harness to connect aftermarket radio to stock harness ? More than likely its the wiring between radio to harness. Check LF RF pos /neg connections. As a matter of fact check all of them . You may have crossed a Rear pos with a Front pos left to right. .Is this a new radio or used from another car of yours ? Sometimes wiring in a radio without knowing wire color code can be a pain.
I installed a aftermarket Kenwood in my S70 using a harness from Cartoys in to factory harness. $25 I think. Good luck.
