I have a 2006 Dodge Charger srt8 and only 1 speaker in the cabin works which is the dashboard speaker in the right corner behind windshield. Sometimes while I’m driving and I hit a bump or if the road tilts slightly, the other speakers will come on for a brief second and then go right back out again. The speakers aren’t blown because they cut on, however when they are off I do not hear static or anything coming from them like it’s getting no power. There is a after market dash unit installed from the previous owner, and I see loose wires n the trunk that look like it may have went to a aftermarket Subwoofer... any ideas on what could be causing this? Or where should I start my troubleshooting procedures to find the source of the problem?

I would go backwards from the good speaker, and see where they join the rest.
