Long story short, after the whole build was complete, we tested the siren with and without rumbler. It is worth mentioning that it is a V1 rumbler amp we are utilizing. When active, the rumbler emits a clunky-sounding tone. Does anybody have videos of a bad rumbler to compare? Could it be wiring? The amp? Thanks in advance.
