1997 Taurus GL - Vulcan - Electrical (alt and Stereo combination)
Baseline voltage = 11.8V (COLD 23° F)
Idle voltage = 14.56V (same temp)
Age = Unknown
(will be purchasing a new battery regardless)
Additions to car = 500 watt Alpine
Everything else stock.
Have been having an issue cold starting lately (i know, it's michigan) and monday, had the battery light come on (after having to get a jump).
Recently also noticed a noise coming from the engine compartment, I am attributing it to either the alternator itself or the Tension pully... anyway that's not my question.
My question is.. With the above noted addition, should I install a larger battery and/or higher rated alternator, or should I be good with stock setup?
ALSO I have read about installing caps to reduce the headlight dimming on the bass hits, cause I do experience this.
What is the best route for me based on your guys' experience?
