    Default Power from battery to boot help?????

    Hi all is there a way of getting power from the battery into the boot without drilling the bulkhead? I have power cable to run from the battery to the boot and wondered if there is an existing grommet or hole i could use? I am installing 2x 3000watt subs with 2x 2500watt amps so i need a meaty supply!!!

    Right, I've just taken a couple of pictures to show how my cable is routed:

    There is a grommet in the corner under scuttle panel on the passenger side.
    To get to this from the inside, take out glovebox.
    I then tucked the power cable under the edge of the plastic inside sill trim all the way to the boot.

    So that's 5000 watts total (peak or RMS ??) so that is 417 amps !!!!!!!! at 12V.

    That is one mighty power consumption if you're drawing full power.

    I hope you have a good alternator, battery and a very good cable to the rear. At that power handling, you are looking a heavy duty starter cabling to minimise losses and heat.

    Might be a good idea to fit an additional battery in the boot to handle the power peaks

    it is 5000watts peak music power, not sure on the rms, i have bought 0gauge cable, its the biggest they had in the shop, i thinks it 0gauge neway, its really thick, bought similar size earth cable. I will see how the battery and alternator deal with it, i will buy a new heavy duty battery if it struggles, and possibly upgrade the alternator if i really have to???

    Remembering the alternator is about 100 amps (maybe 120amps) max charging, you may end up running out of electrical power.
