    Question Amplifier Needed?

    Is an Amp needed to power a carputer? or can it run directly off the battery?

    Is the amplifier only needed for the speakers?

    Go read the newbie FAQ sticky in this forum, it will answer your questions.

    to summarize:
    You run a power supply either off an inverter or a dc-dc power supply that is wired directly to the battery. if you have a head unit with aux in or use a modulator or a tape interface, you don't need an amplifier. If you want to run without a head unit, you take the sound out of the soundcard and run it into an amplifier and out to the speakers.

    How is the sound quality if you use a fm modulator ? Anyone tested that ?

    Not wonderful. I had a modulated CD changer for a while. The difference between a real CD player and the modulated changer was night and day...I had them hook it up when I got a CD player, and never used it after the first time I tried the two back-to-back. Yuck!

    It's good enough for some people though...It will be about as good as a really clean FM radio station....So if you're ok with that...*shrug*
