Ok I was wondering since voltage comes throught the RCA's. Say i have 2 Output RCA from the EQ and the EQ is suppose to put out say 10vrms. Does each RCA have 5vrms coming from it? and if I needed a Y adapter to connect them to a 4 channel amp what would that do to the voltage?

I am mostly posting to follow this, but I have some ideas.

If AC current is the electrical representation of an audio wave, I would believe you have 10vrms to each conductor. When you split them, you are running the signal in parallel which should effect the amperage and not the voltage. The EQ and Amp will have gain adjustments to account for the voltage.

Well i went to the website but i didnt exactly get what i was looking for.The reason im asking this question is because I have a 10vrms sub output and it has a 2 channel output but only 1 of the RCA connection is putting out a signal. So is it still 10vrms coming out of that if i use a Y-Adapter from one connection?

Who knows what you will get. If you have some mystery component with two outputs but only one is working then it seems to be defective. What is it?

In general, all a Y-cable does is create a parallel connection. Voltage remains constant in a parallel circuit but current is split. The outputs on a Y-cable will retain the same voltage but each will have 1/2 the signal level (power) as the input. You will need to compensate by properly setting your gain levels of whatever amplifier(s) you are connecting the signal to.

its a Sound Stream MPQ-6XO. And yes It is defective. im not sure why or how but could it just be a burnt out op amp?

Could be lots of things wrong. I say if it's defective, get it out of your system and repair or replace it.
