    system layout configuration (amp rack) question

    hey guys i was thinking that if i build an amp rack for my 2 amps and caps could i also fit my mobo and hdd in there?

    this would be going in the back of the hatch of a protege 5. what im wondering is how far away from the sub would i be safe to keep mangnetic interference from messing with my HDD.

    my plans are to put lets say my single 10 where it is (flush against the back seat) and then build my amp rack in front of the sub enclosure. so in therory the results would be tri-fold. the amp rack would make maintainance easier for me with the amps/ computer all in one big box, it would stop the sub from sliding around in the hatch (as the amp rack would be flush against the bumper side of hte hatch and sub enclosure, and it would also save me from building two boxes (ie one for the computer under the seat and the amp rack)

    any input?

    thanks guys

    The HDD would need to be physically attached to the subwoofer to damage it... As long as the HDD is at least 12" away you should have no problems at all. I'd worry much more about vibration than magnetic fields. Additionally if the case of your computer is steel or iron (not aluminum) then that'll also act as a shield for magnetic waves.

    I'd think it safer to put it as far away as possible for vibration concerns, but my computer box (wood) is in physical contact with my 3x10" rack of subs, and no problems yet so I wouldn't really worry. My HDD is probably 10" from the closest speaker coil.

    acutally my thinking was that im not going to use a computer case at all and put it all in the amp rack as one big massive case. . .if i figure out hotw to post pics ill show you a rough layout of how i would do this. . . .and since this is the case then me adding a second sub in the future wouldn't be a problem then eh?

    thanks man

    awesome i got wires everywhere since i just ripped apart the previous install

    ok cool i figured out how to post pics will that is a rough layout of what i want to do ( i still have to find a place for hte psu and the inverter but i still got a couple inches of space after the amps.

    i plan building the rack out of 1/2 to 5/8 mdf and then maybe carpet it and then have a plexi window on top. i also have a bunch of spare 90 mm fans lying around so forced cooling shouldn't be an issue.

    there will also be 2 lightning audio 1 farad caps hooked up to a busbar to supply a steady supply to the amps and inverter and i hope to fit all of this in a removable box (in case i need to ever use the spare)

    Hey man, that trunk looks oddly familiar

    I decided to mount my setup under the seat because of vibrations and magnetic fields. In the future I might decide to move it, but I am not sure now. I cant quite picture how the amp rack would look, maybe you could sketch something quick in paint?

    yea here is a really crappy paint rendition of my idea. . . . that is if i don't get vga signal noise from running that long a lenght of svga cable in the car. . .if not it's relegated back to the under the seat idea.

    anotehr way i was thinking of (im getting a dual box soon was to build the same type of amp rack. . .only stealth it and make it look like just a shelf and the sub box would be on top of it
