I just bought the red top 3 months ago and all has been good with the electrical since. Except for this morning... started the car and shorlty after my electronics went out and my rear defroster so I shut the car off. Tried to jump it and a few minutes later I got the same result. My car is an 07 and I do have an amp setup but it does not have a power draw. I just installed an unwrapped header, would the heat have done something to fry my alternator? Also is it possible that the optima is just junk after 3 months?
