So I installed a sound system back in the fall and was having issues with the cars alternator trying to keep up with it, especially if the headlights were on along with the heater going. The heater being the main power killer. When I installed the sound system I only used the power and ground from the stock harness to power the head unit, from there the entire sound system is wired independently.
so I just put a 90 amp ka24 alternator on my a14. Bolted up fairly easily, really plug and play. I thought not having enough amperage was my issue but no, I play the music at decent listening volume, then I turn on the heater and hear my system drop in volume.
anybody have any idea why this is happening?
car for reference is a 1980 210 with an a14
