Does it do the same if the system is off? Do you have a capacitor? Why the hell do you think it was a resistor?

If it's doing this with all your accessories on or off, no difference. I would suspect the alternator before anything.

If it's a fairly large system then yes. How many watts are you pushing? I would check the voltage at the altenator before you replace. My car was doing the same thing and I just threw a new altenator in. $150 down the drain. The old altenator was still good

well the car is completely dead. it doesnt have enough juice to crank over. I dont have a big system at all just 2 6.5 subs in the sails and some components in the doors witrh a hu. I was just going to run it off the monsoon amp. I didnt think it would have that great of an effect on the cars voltage.
