    Quick question about wiring

    I'm using a 4AWG cable from the battery to a distribution block. Coming off the block is:

    Rockford Fosgate P6001bd = 300W x 1 @ 4-Ohms RMS
    600W x 1 @ 2-Ohms RMS

    Rockford Fosgate P4004 = 50 watts RMS x 4 at 4 ohms (100 watts RMS x 4 at 2 ohms). 200 watts RMS x 2 at 4 ohms (4-ohm stable in bridged mode)

    And my CarPC (using M2-ATX)

    The 4AWG cable has a fuse about 1 foot from the battery, and it goes to a 4 point distribution block which will power all three devices above. what size fuse should I use here? I'm using the 4AWG cable that came with this (High current MAXI fuse holder w/ 60 amp fuse): http://cgi.ebay.com/ws/eBayISAPI.dll...9659&rd=1&rd=1

    Does anyone have a link to where I can buy these fuses?

    ok cool, it has a 50amp fuse with it...

    Also, is it recomended to run a cable from the negative terminal of the batter to the trunk or should i just find ground back there?

    Find a solid grounding point in the trunk.

    Clean away all paint, and make sure you have a solid connection. Keep your ground as short as possible.

    On the ground part, You can run it to the back and distribute it to all your equipment or just find a clean spot back there.

    Also on the fuse part. I know I should post a new thread but anyway
    I use 4 channels amp Eclipse EA3422 that has 2x30A fuse. What fuse size do I use at the distro block? 30A or 60A? As of now, I have 30A on the distro.

    you should use a 60A at the distro. Most fuses will not blow until they see about double what they are rated for a few seconds.
