    Compiling parts list... how does this look?

    I'm starting a carputer / audio system project for my 2005 SRT-4. I'd like for you guys to look over my hardware selection and tell me if I'm missing anything or if it looks like something might not work (power mis-matches, etc). I'm fairly new to this, so please be patient. I have a few questions regarding this setup at the bottom.


    Power

    Knuconcepts 0/1 AWG Wiring / Distro to 8AWG for amps and 12AWG for CPU

    CPU

    OPUS 150 watt DC-DC Power Supply for Shuttle

    Shuttle ST62K Barebones System - Socket 478 - ATi 9100IGP Chipset
    (comes with 180W PSU, so I assume the 150W will be sufficient)

    Intel Pentium 4 2.4A Prescott 533MHz FSB Socket 478

    CORSAIR XMS 512MB (2 x 256MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) System Memory Model

    Seagate Barracuda 7200.7 ST3120026A 120GB 7200 RPM IDE Ultra ATA100 HDD

    TOSHIBA SD-R1612 Black IDE DVD-ROM/CD-RW

    Xenarc 700TSV

    Software

    OS: Windows XP Pro

    Front End: Undecided

    Datalogging: Autotap

    Audio

    HU: Alpine Undecided

    Amps: Elemental Designs NINe.1, Elemental Designs NINe.4

    Subs: 2 x Elemental Designs 11Ov.2

    Comps: 4 x Elemental Designs eD6500


    Questions

    1. Will I need a shutdown startup controller with the OPUS PSU or does it have built in control?

    2. Will EMF be a problem with the subs? I'm planning on have both the subs and the CPU in the trunk. The ED Subs have substantial magnet assemblies, how far away does the HDD need to be from these? Is there any kind of DIY magnetic shielding I could use?

    Thanks for taking the time to read!

    So far so good...

    Not going to go with any GPS hardware or software?

    I'm sure I'll do some kind of GPS hardware/software, but I'm taking it one step at a time. My goal is to make the system scalable as well as modular. Once I get the system built and operational, then I'll look into expansion options such as GPS, in-car webcam, etc.

    Opus has this feature.

    We're told there is already magnetic shielding in place in HD's, and Ive seen setups with the HD's close to subs, but I would not do it.
    Looks like a decent setup. Im not sure that power isnt going to be an issue though. I would research your power usage a little more to be sure. Others with similar setups would know.

    You should go with a distribution block that sends 4 gauge to each amp as opposed to 8 gauge. 8 gauge is way too small for the nine.1.

    As for the two sets of components, I would instead go with one EDI.6500s set(in the front), and get the Nine.2 to power them. IMO don't use any rear speakers.

    Interesting. I'd like to investigate this further. Perhaps my brother and I can calculate the EMF generated by the subs and we can extrapolate how far away the HDD has to be in order to not be affected. I'll look into it.

    It is a beast isn't it. 4AWG is what I meant to say...don't know why I said 8. Knuconcepts doesn't even make an 0/1 to 8AWG Distro.

    Hrmmm. It's an idea. A single set could provide better stereo imaging, correct? I'm not sure if this is an issue for me or not. It would certainly save me a few bucks.

    You can mount the HD on the Sub box without any problem (long term vibration from the sub may cause the problem but not EMF).

    Take a look at the Shuttle PSU and Opus PSU to compare the output power for EACH rail. Sometime 2 150W PSU are NOT the same. You should take a look at how many amp on a particular rail (3.3V, 5.0V, 12V) for the Opus and the Shuttle PSU.
    Other already suggest, run a 4GA or 2GA from the battery to the back and use distribution block to run smaller cable to PC, amp, ...

    Yeah, I didn't even think about checking out rail voltages. Good tip!

    Oh definitely, you'll get much better results from sending those speakers much more power than what the nine.4 will send it.

    You can go two ways with this, you can use that nine.4 amp to power the speakers actively(meaning you get rid of the passive crossovers and run each individual tweeter and mid off it's own channel of the 4 channel amp)

    Or you can get the stronger two channel amp and use the passive crossovers. You can probably get better results by wiring them active, but there will be more tuning involved.

    If you want to keep it simple just use the passive crossovers and get the nine.2 amp.

    Don't worry about your rear speakers, the fronts will be plenty loud enough and the imaging will be much better.

    Also not sure if your neon uses rear deck speakers but it would be better to leave them out to allow air to flow through. Those subs will put out alot of power.

    Good luck, and if you haven't checked this out yet, it'll save you some money.

    Also look into getting some edead v1.se as well, if you want to do the minimum of deadening do the front doors and the trunk. I do rec. you do the whole car too, if you don't mind the added weight/cost/labor of that.
