All grounds are common between the batteries. And the batteries ground to the engine block with a heavy gauge link from one/either battery, but preferrably the battery used for starting. The Perko switch addition has no bearing on this and has no ground post. Ground ALL audio components to the same point on one battery ONLY, even if connecting through a distribution block. Double check that each and every audio component has a solid ground. You can have a real problem if an audio component is getting a ground from another audio component via the RCA 'above-ground' shield which typically only terminates to a ground at one end of the signal path.
When you get the Perko switch, ALL audio components (source, EQ, amplifiers, ALL) should be connected to the output (C post) of the Perko switch ONLY, even if connected through a distribution block. Your problem will likely go away. It's a problem if you have the source electronics wired to the helm buss or breaker panel which connects to one battery while the amplifiers are connected to the other battery. Correctly wiring the Perko switch automatically eliminates this particular conflict.
