[QUOTE="chevy_man, post: 5240742, member: 564089"] The pico fuse is on the circuit board. You will have to open the unit and find it, I'd recommend searching other DIY forums for a picture as my 960 has a way different layout. It is tiny, I'd say .5mm x 1mm as a guess (it's been awhile). If you can't find it at first, break out the magnifying glass. If you still can't find it, you may have to pay a few $ for a copy of the schematic. Edit: after re-reading your post, I wonder if you don't have a larger issue. With the pico fuse blown you get a ground loop because your RCA's are grounding through the amplifier ground instead of the HU. The common complaint is just noise, nobody has talked about reduced performance. Do you have your multi-meter on AC? It's not DC voltage just so you know. Re-measure and let me know what you're getting. I'll throw a meter on mine this weekend when I have my tools home and let you know what I find. [/QUOTE]
