Im ready to connect my sub amp up, and i will be using the rca output of my 4 channel amp to connect to the rca input of my sub amp. Im jsut wondering what is the voltage coming out of the output on the rca's? Amp is an Alpine f240. I tired finding the info in the manual and online but couldnt find anything. Is there a voltage range that is usually set for rca outputs. I need it so i can know where to set the gains on my sub amp. Thanks.
the reason im doing this is because right not im still using my stock HU...when i get more money next year i will likely upgrade it, but not at the moment. So with that said, im using the speaker level inputs on my 4 channel alpine f240 amp. So if the output voltage is the same as the input, then what is the voltage of the speaker level inputs after it converts it to line level? thanks again
