You WILL have voltage drop when you try to blast it, that may or may not cause low voltage problems with your amp.

I've had my voltage dip down into the 11's when I turn my system up. But thats with my headlights on w/ foglights, all the other lights on the car, a/c going full blast and with the a/c on the radiator fan turns on and that itself takes some major juice.

BTW..I have the stock 80 or 90 amp alternator..//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif with upgraded grounds to 1/0 gauge.
