    what are good brand power invertors? I will need to be getting one soon, the power supply ill have on the computer is 300watts, so would it be good to get a power intertor rated at 400watts?

    common mis-conception......

    a 300W PSU does NOT mean it will draw 300W, but can handle upto 300W of load...

    for example I have a 300W PSU and only a 140W inverter running in my setup of a Duron 800Mhz/40GB HDD/5.6Inch TFT.... thus the mp3car setup obviously draws less than 140W and ALOT less than 300W

    good brand of inverters?? wouldnt know..... I got mine from www.jaycar.com.au in Australia, but thats prob a little use to you!

    I have a Jensen 300w which my alternator doesn't like at all, I think it's giving it a beating...

    Jensen are usually what people go with. They are good inverters.

    Mag: Cool. Im looking forward to the audigy. I just have to find a pci riser slot for the mobo first though, you will need one too when you get your epia..

    a very, VERY good gain-setting tutorial is here. Also has some other install links and info. they guy is definately a different character, but he knows his audio and electronics...

    my carputer draws 130watts continious (no floppy / dvdrom) off my 180watt power supply unit, and my 140watt Radio Shack inverter (300watt surge) works fanastic.

    Feeding into the head unit works fine too. I have a Clairon head with aux in plugs on the back. Bought a premade cable called monster cable, ran it from my overhead around the back of the cab, above the door and down beside the windshield, behind the glovebox and to the HU. Taped to the cab metal with aluminum duct tape and connected the monster cable to the HU. Using the onboard sound card that only has line level output (no on board amp)

    Could you explain this further?

    most of the old-skool sound cards (like the classic SB16's) had on-board amplifiers.... only 2-10Watts at the most... but enuff to drive non-amplified computer speakers......


    nowadays most, if not all computer speaker sets come with their own in-built amps..... so therefore audio card makers decided to drop their in-built amp circuits and just have 'line level' outputs.. which is good... cause the sound card draws less power off your mobo.....

    make sense??? you dont really want to drive a line level input device (such as a car amp/head unit) with an already amplified signal - even if you did have the choice (eg you were using a SB16/older ESS sound card) since you would get alot more distortion/etc....

    This board is a flex ATX, very small and simple. Id does not have an Amplifier so if you put it in a PC you could not connect cpeakers to it without those speakers having an amp. I didn't need an amp so this saved current draw on the board.

    ok i think im following all this, but what I dont follow is, if my eden board doesn't have an amplifier then why is it distorting so much at high levels? =)
