Dearest Members,

In order to install aftermarket DSP and amplifiers, I am trying convert audio output from factory radio to a set of RCAs. Factory radio has fiber optic output to Burmester amp, so my plan is to intercept that fiber optic cable output and convert to RCA signal. There is an aftermarket converter box with fiber optic in and RCA out. This will result in better SQ than traditional high level input to your DSP.

Please share the location of the Burmester amp if anyone has encountered somewhere in the car.

P.S. Alexfor8, I am certain that your schematics have been a great help for many members. Hope you have something for this as well.

Thank you dlefty!!
Looks like a perfect location to install all necessary gears. Also, looks like the sub can be replaced with 10" JL into the existing enclosure.
This will simplify the install. Only wire needs to be run is the 12V from the battery in the engine bay, and I can utilize speaker wires plugging into the factory amp.

Hey sorry for the revival. What did you use to convert the fiber optic signal to rca?

I doubt the fiber optic in to RCA out converter box worked! Fiber optic is digital, RCA is analog. So your converter box would need to be a DAC that can communicate with the source so it knows the sample
rate of the signal.
And there is No Way it would sound better, as the OP thinks.

No, it will not. You are converting digital to analog. The quality of the DAC matters, a lot. If you’re planning to use an aftermarket DSP, you need to figure out how to keep the sound digital, not convert to and from digital and analog additional times.
