[QUOTE="Buck, post: 8790809, member: 591582"] Sounds like a loose connection on the signal wire somewhere that’s going to your sub amp. Half broken RCA cables can do this, or loose screw or something. The motion of you stopping or shifting momentum is causing changes in wire contact, if that’s what is happening. How often it happens will be displayed by the sub, and the hum comes from a resonance vibration where the wires or loose connection are flapping together. I had a house sub start playing in the middle of the night, when it got colder, due to an RCA head to wire solder coming loose. The amp has to be powered for this to happen. [/QUOTE]
