    ok thanks for the great response. I have a pioneer DEHP-5250.
    I will try a couple of other soundcards and line out devices & see how it goes!
    Note: i did try a discman player (running on batteries) connected through the lineout and that was really soft too...I couldnt get it really loud enough without distorting to test the quality though.

    I noticed you are in OZ, maybe you could try chucking a pre-amp between the sound card/pioneer head unit. Jaycar sell a nice preamp unit for about $150AUS which would help boost your signal if needed. Check it out on the jaycar website/my website....

    Guys the first thing to ask is what sort of hack did you do on our head unit?
    If you got your RCA connected to a wrong spot (may be after the internal pre-amp) then you will get that sort of issues.

    im using the ip-bus hack illustrated on moahdib's page (check his sig)

    i had the exact same problem as bootyslap (basically:quiet sound from the computer, so i had to crank it up, and got distortion from the headunit), but i never solved it either, as my car is off the road... & it was one of those problems i was gonna "get round to"... anyway... here is some more info i gathered today:

    The ip-bus hack is "emulating" the Pioneer CDRB10, yes? so i dug up a bit of info about the Pioneer CDRB10...

    "2. The device connected to the RCA ins must either have an output voltage of 1 volt or less OR have a volume control so that its output can be lowered. Without this this unit will distort and/ or be damaged. "

    from
    http://www.crutchfield.com/cgi-bin/S...re%3D0%26sid%3

    i think this is probably the problem, that either the computers line out is probably too weak, or even too strong... unfortunately, i don`t have an occilloscope, so i can`t test the strength of the signal from my soundcard....

    so if anyone here has an occilloscope (hint hint) , u know what to do (measure the line out level of your soundcard plz.)

    no problem, i`m sure you wouldn`t have done much, if any, damage... manufacturers always cover there own backs, and often err on the side of caution, with these sort of things...

    the only way the unit could be damaged is if it was distorting for a long time, and even then, i`m sure the speakers would go first

    I know on my SB16 isa there is a jumper that will enable the onboard amplifier. The first time I connected it, I didn't know about it and it was VERY obviously distorted with lots of cracking, but after changing the jumper to turn off the onboard amp, the sound was great.
