    Thanyou very much, I am glad you guys like it. Its not like any of this pays the bills, it is just fun and helps out a still growing community. I can do electronics, so I give back that way.

    When/if I ever decide to take the carputer plunge this is an item I would definitely be interested in.

    Love it and I would buy one. How difficult would it be to do a 5.1 setup or make it selectable between 4.1 and 5.1? Just a thought as I have 5.1 in my car.
    The best forum start place is here but damned if I could find it. I had spent several weeks on the forum before finding it.

    pass-thru line out please, so additional amps can be added. Oh, and perhaps an option to connect a physical knob for a hard volume control.

    So if I'm correct, this sounds like a DAC with an amp built in, not really a sound card.

    Will still have to use a sound card or audio switcher to use radio modules, to this date I haven't had a lot of luck with that.

    Price sounds good.

    It is a soundcard. Plug it in, and the OS recognizes a sound card and pumps audio to it. I have no plans for audio input to the PC though. Might be able to have a non-PC passthrough though.

    Just remember every feature is more cost...

    What chip did you plan on using for audio processing? Or is that confidential?

    overall, i think that keeping it at/around 150-250 is a reasonable cost for a quality usb controlled amp-- according to crutchfield-- most 4 channel amps are also in that rough price range of at least $100+ 4.1 amps seem to go for at least $350... keep in mind these are all name brand amps--basically what this amp would/should compete with... while there are definitely cheaper off-brand amps, this would not seem to be the target...

    i can think of 1 change though, unless you know of a amp chipset that can provide the power for the sub(i would say at least 100 watts rms-- i am not familiar with amp chipsets, so it might be cheaper to just include it...), maybe just provide a preout for the sub channel? imo, even just a 4ch amp would be great for most-- as long as they have the option to add a sub.

    while the amp does not interest me (i prefer to build my own setups-- with sound card, and higher power amps) i think that it could provide a huge help to the new people getting into this whole carpc thing by providing a easy plug-n-play solution to the entire amp issue-- lets face it, the idea of hacking together radioshack adapter cables, and discount motorcycle amps to get audio in a car doesn't sit well with most...

    most of the people on this forum are not interested in perfect audio quality or adding aftermarket amps-- most just want clear audio to come out of their factory speakers from the computer that they wanted to install, so a amp like this would provide a great solution that they don't have to mess with to much, and will be designed to work with a carpc..

    wow you do work fast!! By final design I meant designed, tested and ready to be manufactured but the fact that you did so much so quickly is very good sign.

    The only question I didn't see asked here....is how small of a footprint will this end up being? I know exact dimensions are probably not available at this point but is it something that will easily fit in a 1-din space of a dash?

    I wasnt planning on making it DIN sized. I was figuring on making it look like an amp. But like I said, I have not laid it out yet.

    What type of footprint do you guys want? The limiting factor here is not component size (they are small), but heat dissipation. At high powers, this thing will get... toasty.

    That's a DAC, not a soundcard, but I guess I'm just splitting hairs. This may end up being a no go for those that want to run a Directed HDRadio, or XM or Sirius, as I cannot get my Directed or my XM to work with my setup. I'll be digging into my issue more tomorrow and will provide more feedback.

    I realize additional features cost additional $$$. You need to balance between the two to have a successful product. I see someone else has also asked about line in pass thru, probably should also be able to bridge outputs, for those that want more power.


    Just offering suggestions, I thought that was what was wanted.
