Tuesday I had no problems @ all driving to work and after work I tried to start my car and got nothing. Had it jumped off and drove it home with no accessories @ all on...I tried turning on the lights while I was driving and the car bogged and the speedo started bouncing. Replaced the yellow top with an el cheapo battery from Advance Auto. sound is so much clearer and bass hits alot harder.

anybody have any ideas what might have happened? The tester @ Advance confirmed that the battery wasn't holding a charge and the alternator was putting out a consistent 14volts.
