I was looking at the JBL 1200.1 amp on Ebay, but I have been finding many reviews that say it is hard on the electrical systems of their cars, stuff like it eats up battery power quickly. Can anybody here testify to this. I will be powering 2 IDQ 12v2's, I have a yellow top optima and 1 frd Lighting Audio capacitor, should I have any problems with power consumption?

 

You should have a 2 farad cap for over 1kilowatt but you should be fine...

 

I have a JBL 12001 amp running thru a 1 fd cap to my IDMAX. I also have a yellow top optima. Before the Optima, my lights would dim and my battery would die if I palyed the stereo for a while, but after the yellow top the lights don't dim at all unless I really blast my system and I can play my system for hours. You shouldn't have any problems at all with a yellow top & cap.
