Just an idea, but anyone ever try plugging a small electric space heater into a 12v power inverter? I have seen 750watt space heaters and 1000w power inverters at walmart. Wouldn't want to try to use it before starting the car, but it would provide almost instant heat after the car was running.

 

Bad idea. It's already been discussed.... 1000w/12v = 83A. 83A of draw will kill any alternator and/or battery in short time.

 

i warm up for 30 secs then go on! any thing more then 30 secs is a waste of time.. unless its REALLY COLD

 

You live in California. Do you know what REALLY COLD is?

 

28 degrees

 

ha that's chilly. single digits and below 0 makes that feel warm (with your coat on.)
