    need help with wiring power

    ok so im going to put a computer in my car and i dont understand how you get power from your battery to your psu. my car already has a line from the battery to an amp (yes it has an inline fuse also) but its 4 gauge wire. from the pictures on the site it doesnt look like the psu's are big enough for 4 gauge wire to be connected to the terminals. also how would i install another power line off my battery? just unbolt where my amp wire is and just put another line right on top of my amp line and bolt it up? what gauge wire should i use to install the psu?

    btw my computer is going to be something like:
    800meg-1gig
    256-512mb ram
    300gig hdd
    external sound card
    external tv tuner w/fm radio
    wifi card
    travla mini itx case with the cd drive
    an mx2 or opus 120 psu

    i havent decided yet to have the screen take up both radio spaces or just buy a single din flip out one.

    I ran another cable right along next to my main power cable. I used 10g which should be more then enough for this application.this cable runs from the positive pole on battery to the trunk of my car with a 15A fuse box within 8'' of the battery lead.

    Do you have a fused distribution block before your amp? You can just connect it up from there, but put another fuse in the line.

    no its just a staight run line from battery to amp no extra fuse block. so running a 4gauge line right ontop of a 10gauge wont fry anything right?

    run the 4g to a disto block then run your 4g like normal to the amp but starting at the disto block then run another cable from the disto block to the puters' PSU.

    i have no idea how to install one of those

    would that work?

    so how does that work? i just install a wire from battery terminal to one hole on one side of the box and then all the holes on the other side get a direct battery line?

    That's the best way to do it. Although, do you really need 4g going straight to your amp? 8g should be plenty if it's only a foot length?

    If you plan on adding another amp for a sub or anytime soon, it would be worth getting a 1x 4g in and maybe 3x 8g out.
