  • connection from car pc to amp

    Does anyone know how to tap the sub output?
    I read the FAQ
    but the diagram only shows the sub with one RCA output
    would the be fine when connecting to an amp which has the R and L
    rca inputs????

    A sub amp just combines the incoming L and R signals to a mono signal. The sub output on the sound card has already been combined for you. I suppose you could just plug it in to either the L or R input on the amp, but I'm worried that leaving the other input floating would introduce noise. So you could either use a splitter, and feed both inputs, or get one of those little plugs that shorts the center pin to ground, and plug that into the unused input.
