how many watts is your system? how big is your alternator?

Call me what you will, I've got a 34 yellow top in my 1995 Grand Prix and on a really cold morning started my car better than a 2005 Corolla. I've also had it a few years and have no complaints. I also picked up a 1 or 2 amp trickle charger for just over 20bux, just in case. As long as the car is running, it's the alternator that does the grunt work.
