I'm doing research on a future car where i'd keep the stock HU. What does it take to properly integrate a stock HU with a system using a 4 channel amp and a mono amp?
I've read cheap line output converters can cause distortion and signal clipping. I'm looking at these audiocontrol oem integration device comparison but I'm really not sure what I'm looking at.
Which of these will give 3 basic preamp outputs? I'm gonna be going passive so I don't need an equalizer. HPF/LPF from the stock amp won't apply to the preamps if you tap into the speaker wire, will it?
I've always replaced the head unit and ran the preamps straight to the amp so all of this is new to me. I'm just trying to figure out how to do it right.
