    Ok, heres my setup, I have a 4 channel amp, as well as a mono amp. i would like to use a 4.1 setup using an audigy 2nx. Ive noticed that switching to 5.1 using the creative tools and whatnot cuts down the sound of the front speakers quite a bit probably because the sound card is now redirecting sound to the centerspeaker. Now what im wondering if there was a way to continue to send FULL sound to the front speakers and still be able to use the subwoofer output of the device? Like is there any hacks or modifications that can be done to the software to enable an output like this.

    i think you want to set up your soundcard as 4 channel and connect the mono amp to the front via a crossover - this should take the low frequencies you sub needs to the amp. But i am in no way an expert onm car audio.

    i could do this, but i would prefer not to. i do have an electronic crossover, (audio control 6xs) however, i would like to try to not use as many components in my system. I would think going from sound card straight to the amps would be best.

    im sure theres probably some software toggle setting somewhere that could be switched around, but my programming background is fairly small.

    really, you will get sound using a 1/8 to RCA converter, but the sound quality is terrible compared to using a digital output into a digital to analog converter and into your amp(s)

    i use a 1/8 to rca converter and it dosent sound terrible at all, in fact it sounds better than my old headunit. This statement is really only true if you are talking about crappy sound cards and/or really good DAC units

    sorry if this was mentioned before...i skimmed through the threads but i did not seem to find this. i was wondering if i used a sound card what the preamp voltage is because currently i have an alpine headunit and it has a 4v preamp voltage. i want to hook up a carputer and not use the alpine but was afraid of losing sound quality. thanks.

    take a digital multimeter and measure the end of the rca cord using AC voltage setting. heres a hint when measuring, turn up volume at least 75% of full volume to take an accurate measurement. most headunits dont even put up near the rated vrms power until the last few clicks of the volume, but by then the signal has already gone way into clipping and lots of distortion and whatnot can be heard. i think theres only a select few headunits that actually didnt go into clipping when turned all the way up, but i dont remember which.

    ombastic... do you happen to have an rsx by chance?? or visit clubrsx? i think ive seen the same screen name on there.

    By far as I know from my laptop the output is around 0.75v to 1v depended on the volume. Donít know if this is the same output as from a soundcard maybe itís a little higher like 1.2v.

    I think we have the similar problem. Iím using a pioneer 9000 headunit which has also an output of 4v combined with a CD changer. My idea was to hook my laptop up on the same amp so I wonít lose my radio option or sound quality. Since I use my laptop most of the time for navigation. But also want to be able play some mp3ís.
    My only requirement is having my music playing and hearing the fat lady giving me road directions. So using my aux of the headunit is no option since I canít listen to the radio and get the road directions at the same time.
    So I thought of using a Y-splitter but that could give some problems. When I use my radio with the 4v output the same voltage will go thru the splitter to my laptop. My guess is that the feedback of the radio will damage the output of my laptop. I only tried it for a short time to see what will happen. What I found out was that the sound quality what came out was awful for both radio and laptop.
    Maybe I can converter to boost the output from my laptop also to 4v but still the two signals will come together.
    So how can I connect the two signals to my amp and no lost of sound quality or will damage the laptop or headunit?
    Do I really need a signature?

    Could somebody show a diagram that:
    connects the radio to the line-in (mic in) of the pc
    and connects the pc to the amp.

    Thnx

    it's a simple pioneer radio... no option for attaching a cd changer or anything else special
