ive seen in some threads about issues with pioneer h/u's...what is this pico fuse issue??
yep this is true. thats the easiest fix but you can also take the whole HU apart and put a drop of solder on the fuse itself for a permanent fix.i think uts a ssmall fuse in the headunit that goes to the rcas an if you take the rcas out when the hu is on(hotswap) it will blow it an u get ground noise through the RCAs an you have to wrap a bare wire round the rca end an ground it to the radio chassis to get it to stop
what size fuse did u use?![]()
The pico fuse is right below the exclamation point. Its there to protect the electronics in the head unit from and voltage spikes that may come back through the line.
To fix mine I soldered a wire across the RCA grounds and the other side of the wire to a ground point in the chassis. Then fed the wires outside the head unit to a fuse holder.

sounds like your gains are set too high....
Pico fuse issue will be there at ALL volumes
.5 amp fuse.what size fuse did u use?
ok now i know wat it is. i had the same issue with a few pioneers myself that shot engine noise thru the system. and if i kept em i jus broke the unit down and did a gnd from frame to rca on the board and that was the end of it.i think uts a ssmall fuse in the headunit that goes to the rcas an if you take the rcas out when the hu is on(hotswap) it will blow it an u get ground noise through the RCAs an you have to wrap a bare wire round the rca end an ground it to the radio chassis to get it to stop
