installing a sony explode 1600 watt amp with a Boss MP3-3030R head unit, with everything hooked up noticed a voltage drop to 8 volts when i turned on the head unit. it was 12 volts without head unit on. when i disconnected the power ant line from the amp, there was no voltage drop. What am i missing? does my head unit have a problem??

thanks

Was the car running? Could be you just have a bad battery.

Then yes, it sounds like the HU is shorting out your electrical system. Get is repaired (or replaced).
