13.5V nomial is fine. Considering your car is on, things are taking up some voltage, if it reads 13.5V when you have the stereo cranked, you are doing fine.Originally posted by b-easy1988@Sep 23 2006, 11:52 PM~6233494

Do the big 3, use bigger wire, buy a h/o alt and add batteries...
I guess I should have numbered them...Originally posted by S10laynframe@Sep 26 2006, 12:34 AM~6244703
OR the other BIG 3
Atleast 4 AWG high quality wire and connectors..
Battery to chassis ground, alternator to battery, engine to chassis ground.
Makes a bigger difference than you think.
