thumping from subs going from acc to on

Post by MrSo0h0o »

whenever my car is in the ACC position and i crank the engine to turn on, my subs thump. This does not happen when regularly starting the car. Is this a ground issue? If so, why would it not do it when regularly starting the car?

Ground or RCA issue... Probably RCA!
