    Sean boots up his car computer for the first time. Be sure to make sure all positive wiring is connected to the appropriate accessory or capped with electrical tape before you reconnect the positive power cable to your battery. With any luck, your computer should boot properly the first time. Sean's enthusiasm on the video is testament to the difficulty associated with any car computer installation and his relief is apparent when everything works properly.

    Sean Clark, from mp3Car, shows us how the various components in the vehicle are wired. Getting power cables through the firewall is one of the more difficult aspects of any install. In this case, drilling through the firewall of the Altima in the wheel well proves to be the best option. Be sure to use plenty of fire-retardant adhesive on these holes once the wires are fed through. Running the power cables to the trunk can be done along the sill of the driver door. Use care when prying the panel loose. A trim removal tool is recommended to prevent scratching of your OEM parts. The backup camera switching wire and accessory turn on wire are also run along the driver door sill. Wires that aren't associated with powering any device are run along the passenger side sill to prevent interference. These include the front speaker wires, an HDMI video cable, a USB touch cable, a USB iPhone cable, a USB OBD-II cable, a USB cable for an aux input, and a microphone 3.5mm audio cable.
  3. Hardware Review: USB-SA Andrea External USB Soundcard & SuperBeam Microphone Bundle

    by , 12-30-2009 at 08:05 AM

    What is it?

    A USB based sound card with SoundMAX Superbeam array microphone.

    The Verdict:

    Most parts for any CarPC tend to run for a minimum of $50. With the bundle coming in at just less than $50, this is a value for anyone looking to add a sound card and microphone to a system. The microphone is clearly the more valuable part in the bundle and works very well in most environments. The straightforward installation and good sound with impressive microphone pickup make this a good buy.

    See this product on the mp3Car Store here.

    What’s in the box?

    PureAudio USB Sound Card
    Soundmax Microphone
    CD Driver(Mini CD – Won’t work in slot load CDRom)

    Description:

    This product is very basic, almost too basic. With only headphone and microphone jacks you are not able to add additional audio in connections. Because of this all testing of the sound card was done on a home PC, the microphone was attached to the internal sound card in my CarPC. This allowed for Audio IN and my HD Radio to continue to work. The cable on the microphone is long(~84”), this is very handy when connecting to a sound card that is in the trunk.

    The Positive:

    The microphone works very well, and the length of cable is very helpful. The install is also very easy once you download the software from their website (http://www.andreaelectronics.com). I tested voice commands with the top down on the convertible in a very loud garage and it recognized all the commands on first try. This is a drastic improvement over most microphones I have used.

    The Negative:

    The shape of the microphone is designed to sit on top of a monitor, but it does not come with any double sided tape or Velcro to keep it in place. The sound card works but without an Audio In, I am unable to connect external radio sources to my PC.

    The Verdict:

    Most parts for any CarPC tend to run for a minimum of $50. With the bundle coming in at just less than $50, this is a value for anyone looking to add a sound card and microphone to a system. The microphone is clearly the more valuable part in the bundle and works very well in most environments. The straightforward installation and good sound with impressive microphone pickup make this a good buy.
