What amplifier i need for my car PC project?

Q. I have a 2008 VW golf GT with the standard 8 speakers package and i am planning to put a car pc. I will remove the oem Head Unit and put a 7" inch lcd monitor. I will need an amplifier to connect the speakers to it and then the amplifier to the carpc. My question is what type of amplifier i will need? I will have to buy 2 4-channel amplifiers?

Thanks in advance

A. A 4-channel with an optional mono amp for subs.

For a "carputer" the idea is to have a "non-hard drive" based computer that runs stand alone Windows XP/Vista from a Bootable USB drive that runs the music player of your choice using plugins.

Your MP3's are stored on another USB drive that can be removed for editing.

This all ties into your sound system (amps, subs/speakers).

No hard drive means nothing will crash. A touch screen display is really the only other peice of equipment needed that can be custom mounted in your dash as you say.

Look up BartPE and Sherpya. These two guys found a way to run the full GUI of Windows XP on a USB drive (under 600 Mb).

A shuttle style computer is all you need for the computer. You can even have 5.1 or 7.1 Dolby digital.

Here is a good place to start:

How long do LCD monitors typically last?
Q. I bought an Acer X163W LCD monitor from wallmart for $99.99, and i was wondering ho long it will last in a 24/7 media environment. I've already had it on for 4 months 24/7 and don't notice anything changing with image quality and brightness.

A. Typically the backlight is rated 50,000 hours, so do the math to see how many years that is. 50,000/24/365 = 5.7 years. Multiply that by 3 if use averages 8 hrs/day. However, if other electronic components are overrated or substandard, or you physically fatigue a connector or break something, that may shorten its life.

Of all the laptops and LCD monitors/TV's at home or small office at work, I have only seen one failure. A 17" Dell LCD monitor failed at work, but not sure exactly what the issue was, maybe a fatigued VGA connector. At first it would fail to wake from standby unless I jiggled the cable. But eventually it was just a black screen with blinking green power LED (which was usually solid green when on or amber in standby). Same cable works fine with different monitor.

I have a PIII 500 laptop purchased Jan 2000 that still works. And I left it on 24/7 for a couple of years as a wireless terminal for a PC in my basement. Although, the display did go into standby when not in use. I have not fired it up much lately other than to get some data from it (dual boots Win98se and Linux).
