[QUOTE="Wingman0121, post: 7858947, member: 620554"] That setup should not in any way ruin an alternator or the battery. I suspect something else is going on. What is the voltage when your car is off and when it's on? When off you should see around 12.2~12.6v and at least 13.8v when the engine is running. Who installed it? How did they bypass the factory amp and why is it bad? Is it still in the vehicle? Maybe the factory amp has a shorted output and pulls a ton of current when it gets turned on. I had a Profile AP2000 amp that had no visible damage but a shorted output device and when it gets turned on it immediately starts to pull over 25 amps (the max my DMM can handle). That thing could have ruined the battery/alternator if left hooked up in the car... alternator unable to keep up with current demand, unable to keep the battery charged, the rest of the car is still using power... equals to dead alt and dead batt.
