[QUOTE="TRaGiK, post: 5915594, member: 610004"] Just checked for that. Normal voltage with the truck running with radio and all accessories off is 13.85 volts. With a/c and headlights on, and the sub thumping, it drops to 13.40 at the battery. I checked voltage at the battery, amp, and head unit. At the head unit, voltage drops to 13.35, and the amp drops to 12.9. I'm pretty skepticle of it being a voltage drop issue since it's dropping less than 1/2 a volt, at the HU and still well above 13 volts. Any other ideas? FWIW, the head unit doesn't start clipping the door speakers til after it's been playing for 5 or so minutes (after it's sat for 30 minutes or longer). I thought it might be over heating as it gets pretty warm on the heatsink on the back, but even after turning it off for a few minutes and letting the a/c blow on it, it still clips. [/QUOTE]
