Well my car won't start, I have to pop the clutch to get it started. when trying to start it, It sounds like my battery is dead, but I bought a new battery last weekend. When driving it, at idle the headlights, interior, gauge lights DIM. The RPMS sometimes go down and it studders and dies. It's a really weird problem, I replaced the battery, last weekend, it started fine had no problems 'till tonight.I replaced the alternator 5 months ago. all the belts are nice and tight. Ohhh also I had the cd player on, and the speakers started making this weird noise and even when I lowered the volume, it'd make it 'till I took out the CD. I'm gonna take my car to Autozone to have the alternator tested, some help plz?
