Hello all,

I have been trying to figure out a way to transfer signal from RCA jacks to go through a line drive then to the amp whena switch is flipped and if I don't want to use the line driver I can shut it off and listen to the sound system normally. Any information or diagrams will be helpful. Thanks in advance

One relay per channel.

30 to the input of your amplifier. 87A from your deck. 87 from the line driver. Whenever you energize the relay by placing 12 volts across 85 and 86, the signal from the line driver will get to the amplifier. With no voltage across 85 and 86, signal from the deck will get to the amplifier.

Won't I need 2 relays per channel since there is a a signal and a ground per channel? And should I have to worry about any signal interference?

The RCA grounds are common. Leave them connected. No need to switch them.
