No Sound After Speaker Upgrade: Suspecting Short From Dash Pillar Speaker Installation

Does anyone else use Lasfit LED backlights? I've had mine for over 6 months now. They work perfectly. Honestly, sometimes I even forgot about them. That's the way it should be. Just to share a tip for anyone who hasn't installed them yet on their truck. They only work when they are in the bulb sockets one way. So put the bulb in the socket and test them before placing the socket back into the light housing. If they don't work, just pull the bulb out and switch them around. I hope this makes sense.

I must have a short in my one-dash pillar speaker when replacing the factory premium JBL speakers because I recently lost all sound inside my truck the other day. Music, tones, everything.

I don't know if it's safe to cut the factory harness off and direct wire to the new dash speaker. I guess what I'd do is retrace my steps. If I could, I'd probably figure out what I did wrong and check all my fuses.

Also, someone advised that I need to disconnect the battery before doing any electrical work next time, which I completely forgot about.
