    Well, you can use an amp with stock speakers, but you do run the risk of blowing them if you turn the volume up to high. Of course you can blow pretty much any speaker by that method.

    So what would be a good, low power amp for use with the stock speakers? The guy at Circuit City audio told me to use a head unit.

    I don't think he was very bright and understanding of what I wanted to do.

    Using a head unit will be the safest way to do it. You can use an amp with stock speakers....just keep the gains on the amp low untill you decide if you want to upgrade your speakers or not. Then again, even a new head unit can blow the stock speakers if turned up high. I've done it. It just comes down to being careful with the volume. Any amp that runs 45watts RMS or less is a good amp for your needs. Just remember...be careful with the gains, if it sounds distorted...then your putting to much power to your speakers.

    Thanks for the help. I am so new to this CarPC thing, and I want to make sure I fully understand this... The CarPC would get run to an amp, preferably 45RMS or less, and from the amp, get run into the car sound system.

    After some research, it seems Road Runner is the best front-end, so I would use that, and when I need to adjust the volume, I can do that from RR and it would adjust the volume being output from the CarPC, which means I need to leave the amp on a decent setting for output, so that adjusting the CarPC won't make it too loud (or too quiet).

    I posted a thread in the Newbie section, but I guess I'll post some of that info here. I updated what I want to do to make this work, and these are the components I'm going to use...

    And for the CarPC...


    Specs:
    Complete 4th Generation 1.6GHz Dual Core Car Computer

    Our complete 1.6GHz Dual Core Carputer is pre built and packed full of hardware including our redesigned aluminum Mini ITX chassis, a M2-ATX automotive grade power supply, 120G Toshiba 2.5" SATA hard drive, Intel D945GCLF2 motherboard with embedded Dual Core 8W 1.6GHz Atom 330 CPU, 1024/1G DDR2 RAM, and USB DVD combo drive.
    Ideal Features

    * Exclusive vibration and shock resistant hard drive mounting system
    * Regulated 12v output for LCD monitor power
    * Smart 160W automotive grade DC to DC power supply features automatic startup and shutdown with adjustable timing settings, and more
    * The included USB DVD drive can be mounted remotely for easy access.
    * 7 pin S-video output for use with existing factory NAV/GPS screens (compatible with RCA to S-video adapters)
    * VGA video output for high resolution monitors
    * RCA audio outputs for easy audio integration
    * Built in Bluetooth for wireless keyboards, hands free cell phone, and more (keyboard, software and microphone not included)
    * Locking power harness
    * Built in mounting brackets for easy installation
    * 90 Day Parts and Labor Warranty

    New Features:

    * Hard Drive and System LED Lights
    * Redesigned air intake for enhanced airflow and increased cooling
    * RCA audio line outputs
    * Miniature reset switch

    I would also do a Slot Loading DVD Combo Drive, Internal 802.11 B/G Band WiFi w/ External Antenna, Sirf III USB GPS Receiver, and Increase Hard Drive to 320 GB. So for the screen and the CarPC, it would be like $800 or so. How does this system look? Any reviews from anyone?

    Now all I need to do is find a suitable amp from somewhere. Any suggestions on one for what I need it for?

    I dont have any personal experience with either of those maybe someone else. but I gave my suggestion on an amp earlier in this thread, from the amount you have in your pc and screen, the amp is like pocket change lol...

    You could always use motorcycle amps. They are small and cheap. At the time when I bought mine, they were up to 150 watts, so 75 watts per channel. Now they have versions that are 200, 300, and now 500, in a small amp that is about the size of a 2 desktop hard drives stacked on top of each other.

    You your best bet if you don't really need an amp, is to get a head unit that outputs around 45-50watts X 4 channels to your speakers, and has an RCA AUX Input. Pioneer has a few decent models that provide enough four channel output power, including Aux In, so shop around.

    You will also need to pick up a wiring harness adapter from Scosche to make the installation of the head unit painless & trouble free. The one you need is PN:NNO38 to adapt your factory wiring harness to an aftermarket head unit.

    Wire up the new car stereo head unit, then connect the RCA output from the carPC above, to the Aux Input on back of the head unit and enjoy. That's it!

    I have never been a big fan of HU on a CarPC only because most headunits don't have surround sound for the AUX input, just simple stereo. If that doesn't bother you, then go with a HU. If you are going for horribly superior sound though, I'd X out the HU.

    That's definitely personal preference, I still don't see the point of having surround sound in a vehicle. To each their own, you know?

    My setup is headunit-less but there are some advantages to going the headunit route.
