Chosen Solution
I just finished hooking up my amp and sub. Everything is correct. I have double and triple checked it all. At the battery terminal, the power wire has power. On both sides of the fuse, the wire has power. However, when I go to my amp (I even cut the wire open at the end to check), there is no power to the wire on the amp or inside the wiring jacket. Suggestions? I really don’t know anything about electronics, so if this is dumb, sorry. Sidenote: I also don’t have power to ground or remote (that’s not what I’m worried about tho. I should still get power through a wire from the fuse to the back.)
Hi @lil_chef , What are you connecting the voltmeter (or test lamp) to at the amp besides the power wire? If you are connecting it to the amp and the amp is not earthed you won’t get a reading on the meter. If you are connecting the meter(or lamp) to the end of the power wire and chassis earth somewhere in the vehicle then first verify that you have a good earth connection to the meter and if still no reading the wire is broken between the fuse and the end of the wire. Did you run it in or is it an existing wire that may be routed via the ignition switch etc, or something? (I assume that you are installing an amp in a vehicle - you didn’t give much info on this e.g. make and model of head unit, amp , vehicle etc)
