    Laptop and low sound volume problem

    So I've got everything working with my laptop, audigy zs notebook (pcmcia card) going to my stock amp and speakers. Sounds terrific, but the volume isn't very loud. I searched around and found out that many laptops (and their corresponding sound card solutions) don't put out very many (volts?) when producing audio, so the amp can only boost it so much.

    My question to all you laptop users is: what are you using to get good quality, LOUD volume out of your PC? Maybe you have a better amp (pretty sure mine sucks) with a gain control, or you're using line drivers...

    Someone sing out about their awesome sounding laptop CarPC with LOUD volume. When I say LOUD, I don't mean shatter-the-windows loud - I mean you can hear it very well on the highway with the windows open. I need a solution, I'm starting to doubt the huge investment I've already made in this CarPC.

    perhaps the gain on your stock amp isn't at the same level as the laptop
    i know that your laptop is sending a good signal with the audigy card, so maybe it's time to think about an amp?

    I would reccomend definitly ditching the factory amp, even the speakers. If you even want decent levels out of your laptop you're going to have to get a well powered amp and new speakers. In my opinion, its the only way to do it right. It maybe alot to ask of your wallet, but if sound is a even a remotely important aspect of your particular project then thats what you'll need to do.

    I'm really trying to not redo the entire thing, so that when I sell it I can put it back to it's original state (I have a hard time most used car buyers will see my CarPC modifications as a selling point).

    I'm still interested in finding out about those laptop configurations that people are happy with.

    The only thing I can think of other than gutting out the entire system is to connect a line driver to the output of the computer before it is inputed into the stock amps. A line driver will increase the output levels of the signal possibly to more desiriable levels what you are looking for.

    Yea,

    A line driver should do the trick. On my E36 328 BMW I measured the audio levels with a scope last night. I found that the level is centered at 6v DC with a swing of +/-5v before clipping. Now regular PC audio card puts out around 1-2v, so amplification is needed. I need a 4 channel line driver, I found a 6 channel one but its nearly $130 and will boost up to 8V RMS. See:

    Anyone know of any other line drivers worth considering, or a 4 channel version?
