I have just bought a Sony CDX GT730UI head unit to replace my double DIN Symphony head unit with BOSE system. I am also fitting an amp and sub.
From what I can gather the existing system is rear amplified and not fully amplified ???
Therefore I think I need the auto leads harness PC9 – 401 ????
The manual for the Sony h.u. states connecting active speakers with built in amplifiers is a no no, therefore I was wondering if the BOSE plug in the boot feeding the tuppleware sub could provide me with the un-amplified supply to take back to the h.u. ?? ( without the need to take direct feeds from the actual speakers)
While in the process off running the 12V power lead to the amp is it worth running a pair of RCA`s and a amp remote on? Or can these be picked up from the BOSE plug???
I ask this as I was wondering if the BOSE plug in the boot is of any use now that an aftermarket h.u. is in place??
Also, there are three configurations for powering the h.u.
The supplied Sony harness
Yellow – continuous power supply
Red – switched power supply
(stereo connector) Yellow------Yellow (car connector)
- (stereo connector) Red -------- Red (car connector)
(stereo connector) Yellow ----- Red (car connector)
- (stereo connector) Red --------Yellow (car connector)
(stereo connector) Yellow ------Yellow (car connector)
- (stereo connector) Red -------- Yellow (car connector)
Red (car connector) not connected
(method 3 for cars without ACC position)
I assume its either method 1 or 2 ???
