What AMP's are you using to be able to use SPDIF / Optical ?
I can not seem to find anything Non Discontinued !!
1999 Black Pontiac Trans Am
CarPC's in F-bodies
How To Relocate Climate Controls on the 97-02 F-body Cars
(AMD Sempron 3000+, Opus 150)
Car PC system is out, Alpine system is in.
I use a Zapco DAII to get the optical out from the PC to the amps. I do all my processing and tuning with Zapco DC reference amps and the software they provide.
