I've got a 2000 SVT.
This weekend I'm getting a new headunit (Sony CDX-M620) and speakers (Boston FX8) installed. I have the amp bypass wire from Crutchfield and when I told the shop that I had it, they looked at me funny and said they probably wouldn't need to or that I would want to bypass the amp.
Should I have the bypass installed or should I go through the amp?
