I have a 2018 Dodge Challenger with the factory Alpine "premium" system (comes with factory amp). Originally, I had installed a Rockford Fosgate DSR-1, which handled the OEM integration and also served as the DSP. I've decided to replace the DSR-1.
So I will now be using the AmpPro 4 for OEM integration and a Helix DSP.3 for DSP. I already have an AmpPro 4 with the toslink adapter installed. Since the AP4 has an optical-out and the Helix DSP.3 has an optical-in, I'm trying to decide if I am better off going digital between the AP4 and the Helix or stick with analog.
The AP4 will be installed in the dash and the Helix will be installed in the trunk, along with a JL Audio 6-channel amp (XD600/6v2).
To me, it just seems that digital would be cleaner and easier. Instead of running (4) bulky RCA cables from the dash to the trunk, I could run a single optical cable - and the optical cable would eliminate any potential noise-related issues introduced between the two components. I do realize that I would lose head-unit fading and there is some talk about jitter, but is there really any reason NOT to go digital in this case? I have read multiple threads on here about digital vs. analog, but wanted to talk specifically about my install/gear (AP4 in dash, Helix DSP.3 in trunk, etc).
Thoughts or experiences?
Thank you!
