New info:

Battery is 4 1/2 yrs old :P ...didn't realize that at the start of all this, time flies

Guys at AutoZone say it is probably just an old battery that can't get it up any longer.

Voltage stays between 13.4 - 14.2 with or without audio stuff on.

Cooling fan ( that big white plastic fan right behind the grill ) does not seem to come on anymore. The maintenance required light is on... possibly low battery voltage or a result of the fan not coming on.

What triggers that fan? Engine temp?

Jumped the car off, ran it for about 10-15 minutes. Battery voltage is same as it was before jumping car. 8-9v. So it obviously did not charge any. I'm thinking the fan might have not come on because the engine was just cold.

I think I'll get a battery this evening but I'm afraid if something else is wrong then the battery will just slowly drain and I'll be right back where I was. :(

Any more ideas with this new info?
