Hey 7G world! I installed a subwoofer in my GT with the 301A package (no factory sub). I tapped into the brown/blue (positive) and gray/brown (negative) speaker wires and all went well. Battery to the capacitor to the amp, no issues. However, on day-two, my sub began playing engine noise consistently between 2-3k rpms. It sounds like dragging a bass drum over railroad tracks. Before and after 2-3k rpms, no engine noise is present. I lowered the LPF from 110 to 50 and the sound of the engine noise decreased but did not go away. Any ideas about whatās happening?
