    @Will Albers - so I can get an adapter that will allow me to hook into my factory amp? Is it really that easy? I would love if that were the case...

    Edit: I found this item. Will this allow me to take RCA audio from my soundcard and simply plug into my factory amp and speaker setup? http://www.cardomain.com/item/PERSVEN4?vq_id=none

    It says this:
    Typical Applications
    Aftermarket Receiver to Factory Amplified System
    (such as Premium, Infinty/JBL, Mach, Bose systems)

    So, aftermarket receiver = pc soundcard?

    As a matter of fact, what I had planned out and later shared above was never meant to be for factory speakers.
    So in a way I'm glad you're agreeing with me.

    Sorry - I was speaking to Puff.

    audio layout

    @Red - Could you make any suggestions for my setup? If I were to rip it all out, what would I need to replace it with? I'd like to keep the cost low, but get decent sound. I would prefer to keep the speakers, but i am looking at all options right now...

    P.S. Thanks to everyone for the replies...

    P.P.S. I can get good deals on Sony car audio stuff, but I have heard they aren't that great. Any opinions on Sony amps or speakers? Thanks again!

    If you PM me your VIN-number I can post the scheme of the OEM audio which is in your vihicle.

    @Will Albers - that's good news. Another user brought up a point though. Since that adapter is for aftermarket HU to factory amp & speakers, will the signal from my soundcard be powerful enough? Logic is that aftermarket HUs are powered...

    I emailed this to the manufacturer of the SVEN4...

    I would like to know if the SVEN4 would allow me to connect a RCA output from a non-powered device (a computer soundcard in this case) to my OEM speakers and amps. I have a 2003 Audi A4 with the Symphony (non-Bose) double din headunit. I will be removing the headunit and replacing it with a touchscreen lcd in the dash and a computer to provide the audio. I do not want to replace the factory speakers or amp, and am hoping the SVEN4 will bridge the gap between my computer and factory speakers/amp. Thank you.

    We'll see what they say...

    A decent sound card will provide enough juice to work fine. I'd bet the adapter can handle .5 volts all the way up to 5+.

    Get the adapter...

    Here is the wiring diagram for your 2003 Audi A4 1.8t.

    2003_Audi_A4_1.8t_radio_amplified_notBose.pdf

    It should be noted that there were 3 different sound systems available for the sedan: 1) Regular system without an amplifier. 2) 10 Speaker amplified system. 3) The Bose system.

    From the information you gave, I believe you have the 2nd system: amplified, but not Bose.

    The factory amplifier is for the 4 rear speakers (2 on the left, 2 on the right) as well as the factory subwoofer. The 5 front speakers (2 on the left, 2 on the right, 1 in the center) are powered directly off the head unit.

    It should be relatively easy to figure out the wiring for the factory amplifier using this diagram and a multimeter. (Just guessing i would say pins 1,2,3 are the line-level audio input signals, probably left,ground,right. Pin 9 looks like the amp turn-on signal. 14-21 are outputs to the speakers. And 22 and 23 appear to be Ground and Power.

    For the front speakers you will need an additional amplifier. Crossovers are not necessary as they are built-in already. A 2 channel amp will suffice if you forget about the center speaker. If you want to use the center speaker you may need to go to a 4 channel amp.

    I hope this helps - Good Luck.

    @Walky talky20 - thank you for clarifying that. I do believe I have the 10 speaker with amp package. I am working on a diagram to show how this is all going be wired up. The attachment you posted is invalid though when I click on it. How big is the attachment? Maybe you could email it me... pm for the address... thanks again.
