without back and stock alt and batt -- Yes, i think it will hurt the amp but you will hurt smthing else as well //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
first off u will have big dimming issues, low voltage, u will drain your stock battery.
Get the Orion.... as you upgrade drop the impedance. One of my favorite all time amps. Prepare for dimming lights if you run at 1 ohm on stock electrical. Just my $.02
