    Volume control

    If you use an amplifier with no head unit as opposed to a head unit with a car pc, do you lose anything relative to volume control?

    or you can just do the volume through the touch screen

    Let me rephrase. Am I sacrificing anything to the level of volume I can achieve? Will the sound be as loud and rich as it would through a head unit? After some more research, I'm assuming yes. But any tips to help improve that or any other advice is welcome.

    You just need to match the amplifier gain to the audio card output voltage.
    This is easier than whit a headunit because most PC dont output distortion at 100%.

    to improve the volume your option is to either get more efficient speakers or more powerfull amps.

    if you get a soundcard with high enough voltage on the outputs then you will have to adjust the gains so it wont clip while this doesn't give you 'added volume' you will benefit from improved sound

    well, it all depends on your setup.

    You can go with a very high end sound card and have dobly 7.1 in the car if your want.
    You will have to do a little research as to which sound card will suit your needs.
    Look for ones that have a higher output voltage if you're looking for spl. If you're looking for sq, you're still going to need high end stuff.

    there are quite afew people one here who compete in sound competions with computer setups (red and durwood come to mind).

    me? I'm using an old audigy 4 and kxdriver project drivers. The sound is great (at least as good as any head unit I've used) and it will go loaded than I would ever want to go.
    Others are jsut using on board sond, and have great success. Depends on what you are after and how picky you are I guess.

    but you need to put time and effort into proper setup to avoid things like ground loop noise, static, etc. Just like you would in a "standard" head unit setup.

    start with good quality components, take the time to do a quality install and you'll be very pleased with the result.

    Good luck

    i agree with most everything you said except for the above statement.

    higher output voltage doesn't do anything for spl, it does however improve sound quality

    Hum, has someone explained it to me, higher output voltage let you use lower gain so it reduce the noise floor. So it can be usefull if you have lot of noise, but it does'nt improve sound quality over a good 2v preamp.

    well. it's benefit is when noise is introduces it's at a smaller percentage. say you have a signal that is a value of '10' and due to your installation you add '2' points of noise. now say you have a signal that has a value of '30' and you add the same '2' points of noise. now your gain on the amp is lower with the signal that is at '30' which lowers the amount of noise you actually hear.... did i just hack up my explanation?
