    Integrating new carpc into 2004 honda accord

    I am in the planning stages of building my first carpc and have been reading for hours. I have an 04 accord which I will not be able to remove the stock hu from. The screen will go into the lower cubby. see pic http://i203.photobucket.com/albums/a...malser/CP5.jpg

    1. Should I hook up an amp straight to the carpc using an amp? If I get 3.5mm to rca adapter, how do I plug that into a 4 channel and and a mono sub amp? Or should I use car2pc to the stock hu? Then use line out converter to the amps. If I use the carpc straight to amp, what soundcard should I get, I will have a pci ex-x 16 and 2 pci slots on mobo

    2. The main things I want are gps, mp3 storage and playback, and sirius sat radio, on a user friendly front end. Centrafuse is what I'm leaning towards. Are these components overkill and can I save $ in any areas? I am pretty sold on the ssd as I use them on my desktops, and the processor seems to have a much higher performane than those in the $50 range, and its only 65watts

    MSI G41M-P26 LGA 775 Intel G41 Micro ATX Intel Motherboard $50.99

    Intel Pentium E5700 Wolfdale 3.0GHz LGA 775 65W Dual-Core Desktop Processor BX80571E5700 $66.99

    -$40.00 Instant $168.99

    Additional: m4atx psu, bu353 gps, 7" screen, sirius module & usb interface, not sure which version of windows would be quickest to load and be stable in long periods of sleep or hibernate.

    An important question... Do you plan on keeping/using the HU? That answer will drive your design decisions.

    If you want to use the OEM head unit to drive audio: you need an adapter to feed PC audio through the AUX/XM port (white one on the back). If your head unit lacks that (there should be a button labeled as AUX/XM) then seriously consider buying one off ebay that has that. You can't remove that unit entirely without rebuilding a climate control system yourself.

    Alternatively, as I am doing, you can feed a 3.5 mm jack to RCA stereo cables and to an amp that can spread thru 2 channels to 4 (the new Alpine amps can do this, for example)

    Ryven: what about an amp for a sub?

    I cannot remove the stock hu, although I don't mind it being there and not being used because it shoes temp, time, I can store 6 cd's in it. I wanted to know what would give better quality sound, pc2car, then out the stock hu to a line out conv. Then to amps. Or just pc to amps and if this, then which sound card <$100 is the best option? I am leaning towards just pc to amp but am unsure of exactly how this will work, I have seen some sound cards with rca jacks but don't know what features to look for.

    Some people have pretty good sound quality using the onboard audio - just pick up a 3.5mm to RCA cable (or a 3.5mm to RCA splitter, and a set of twisted pair RCA cables) and run it to your amp. I've used a USB-DAC, and thought the sound quality was very good. It was less than $100, and you can find them by googling for USB DAC.

    If you want to save some cash, and you have time to experiment, start with your onboard audio and see if you like the quality. If not, then move up to a USB soundcard/USB DAC.

    being that the radio needs to stay there, i would run the pc through it. the volume control is going to be a little faster then using the windows volume control, and you will be able to keep am/fm/cd for when the carpc acts up.

    sound-quality wise, you will not have a problem-- yes, it might not be perfect, but you will only notice it unless you read Stereophile magazine, and think $500 interconnects sound reasonable.. but then, you wouldn't be keeping the stock radio in the first place, no matter what functions it controls..

    tray-load designs are not recommended for car use because of the chance that the tray can break while loading a disk. slot load designs are preffered..

    ram:
    in-car, i don't think you need any more then 2gb of ram. if you want to use hibernate, the less ram the better. everytime you hibernate, whatever is stored in the ram is written to the hdd-- the more ram you have, the longer it will take to hibernate.

    mobo/cpu:
    i think the e5700 is a little excessive for most tasks. i personally run a e5200(or is it a e5300?) pentium dual core. my system is built around audio processing which is pretty cpu intensive, and i rarely go above 30% cpu usage.

    windows:
    i still prefer xp, though win7 is slowly growing on me. win7 has hybrid sleep/hibernate, which, my understanding of it is that it can be put to sleep+save the hibernate file at the same time. xp doesn't do this.

    imo, stability has more to do with your hardware/software setup then OS selection-- i do a poor job setting up software, and as such, i have just as many problems within xp as i do with win7...

    Just a quick note about the Accord audio quality. I also have a 2004 Accord with the MB onboard sound driving a small 400w 4ch Alpine class AB amplifier via an encoder driven hardware volume control.
    I’m still using the existing Accord speakers for now and there is, in my opinion, a 100% improvement in sound quality compared with the (now removed) old Head unit/amp.

    Mickz has the most completely custom Accord build I've seen on a 7th gen. He was my inspiration for pulling my head unit. Find his build thread. Great stuff.

    wow! That is the most detailed car mod I have ever seen. Very impressive

    Ryven, how did you pull your hu, did you use microcontrollers and remove the stock hvac controls like Mickz?

    I think for now I will put the screen in the cubby, especially bc it will have less sunlight reflection down there.

    you can use 3.5mm to rca adapters to get the audio out of the carpc without needing something that uses rca connection.
