As the title suggests i was eating lunch and heard 2 girls playfuly screaming out the front so i walked up to the front door to have a gander to find the girl next door and her gorgeous friends washing their cars and soaking each other with the hose

. So i thought what can i do to have a perve without making it obvious. Just installed a new sub and amp i put in a few days ago so i thought id set up the gains and the onboard EQ. anyway while i was having a gawk my screwdriver went off target and must have earthed the + output on the amp to the amp chassis and allmost shot the cones out of their chassis. Now the alpine amp flashes the error code "RCA ground floated" so i tried a new rca lead to no avail,
does this mean i have stuffed the output from the headunit ?
P.S. stereo still works fine except that it has a bad "humm" in it now
thanks in advance
