Hi there,

First, check for any loose wires if the system was just recently installed - one of the wiring harnesses could have worked its way loose.

If the wiring is intact, measure the voltage getting to the speakers to check if the system is outputting any signal to the speakers.

If the speakers aren't getting any signal, try performing a factory reset on the system.

Kindly rate my service 5 stars at the top of your question page if my answer is helpful so I am rewarded for my time; tips greatly appreciated :)
