    5.1 Sound cards

    I just picked one up a few minutes ago (AOpen AW-850 Deluxe), and will be installing it tonight, but I have a couple questions first. My setup in the car is basic.... Factory HU, FM Modulator, 1 amp in the back powering 2 10" subs. I am planning on running the sub out to the RCA input of the amp.

    1: How should I hook up the audio going into the HU? Should I use the front or back output of the sound card? Is there a way to merge the two?

    2: As far as the amp and subs go, I just spliced into the speaker wires for the back speakers and ran them to the amp, which has two inputs, speaker wire and RCA. Can I / Should I keep the existing speaker wires going in to the input of the amp, or should I take them out all together, and have only the RCAs from the sound card. I would like to have use of the amp and subs when i am listening to the radio and such, but it is not the most important thing.

    If any other of you 5.1 users have any tips I would be glad to hear them.

    how are you going to control the volume of the subs while listening to the computer output. if u have the "main" signals running into the head unit you will have volume control for them, but if you lower the volume on the HU, then the subs are going to be maintained at the volume of the computer, that could be much less or much greater than the HU.

    unless im missing something here.... personally, i think that a 5.1 card isnt going to do what you think it will. well, it will output the sound that you want, but you are going to have no control over the sub output.

    Your right! I didn't even think about that! Well crap! Well I guess I can control the volume from CobraIII or Winamp, or maybe relocated the gain knob to the front seat. Any ideas?

    Well it is all hooked up in my car. As far as controling the sub out line, could I use an in-line volume control, like what some headphones use? Or maybe hack apart a wall mount volume control like this? I should only need mono since the amp output is only mono. But all in all the sound is much better than with the built-in sound. The bass from the amp out isn't very sharp but it could be the way I hooked it up.

    BTW does anybody know where I can get an in-line volume control? I searched all over but all I found was headphone reviews.

    you could simply turn up the HU volume full blast and use the computer to controll volume of the system. Even then when you use the HU's radio the subs will not play. Also the factory HU will probabbly make all sorts of noise when cranked even when there is no input, espiacially if you use a tape deck adapter.

    radio shack sells dual audio curve pots for this. You will have to solder the wires on your self and buy a knob for it.
