    You could probably get away with splitting the audio output into 2 RCA pairs as it is going to be amplified anyway.

    Two of those will do.

    If sound quality isnt great then you'll need to get a pre-amp which will give you two RCA outputs from one input while keeping sound quality as good as the original.

    Thank you for your reply, but i am not sure i understand what you say....two of those cables will do, to split the signal or ??? and do i need a 3 amp, to get the correct signal ???

    You could buy two of those cables to split the signal (see pic)


    Or you could simply strip the cable and join on another RCA pair which is basically doing the same thing.

    Or for the best sound quality you'd need a pre amp to keep the signal strong, when you split an audio wire you take someof the signal strength away, but as its being amplified anyway you'll probably be ok splitting it.

    I have the laptop running audio to my pioneer head unit through an AUX-in box. The head unit has 3 RCA outputs so i've had no need to split them. Easier for me as i had all my amps connected to the head unit before i started.

    Glad to be of help.

    What kind of sound card do you have?
    Does it have more than one output?
    Depending on your sound card you might have a .1 out (sub out). Me personaly I'm going from my sound card to a Clarion pre amp/eq to my two amps.
