Adaptor For Bose Head Unit in 2002 Seville

[packer]

Hi Folks,

I want to keep my stock head unit, and retain fader functions. but as you all know there is only 1 pair of audio L/R going into the amplifier, the fade/balance functions are done inside the UX9 amp.

I am looking for a after-market box that will decode the serial data stream going to my UX9 amp.

So this decoder would need take L/R in & Class 2 serial data in from head unit, provide L/R F/R out to an Rockford Fosgate 3SIXTY.2 then on to a after-market amp set-up
