    Need help

    My bass amp is an lanzar opti7001d which Is rated at 7000 @ .5 and 5k at 1 ohm I'm wiring it to 1 ohm so now my question is I orderd 100ft of knuconceptz 0 gauge which is going to be my power wire with 2 300a fuses upfront. I have 2 d3400's up front and I'm going to be running the 0 gauge to my back battrie which is a d3100 instead of running 2 negative runs would it be fine to ground the amp to the back battrie and then ground that back battrie with 4/0 gauge welding cable that can handle 600 amps? And then just do a nice big 3 upfront with the knuconceptz also? How should my voltage hold up I also have a brand new mechman 270a alt? My other question is where can I order some nice 4/0 welding cable from?

    flexaprene is nice welding cable. i use it for my car and on welders. their 1/0 is rated at 350 amps up to 50 ft. 2 runs=700 amps. i don't know what knu is rated, but it should be sufficient. 4/0 is a tad overkill. that 100 ft will go a long ways depending on the vehicle and however you decide to wire it. what voltage you running?

    Its a 2007 Tahoe and I'm running 15.3v mla module it's over kill but I also have a 4 channel amp and I just want the voltage to be solid but is that grounding idea a good idea do you see any problems with the way I wanna do that?

    you mean grounding the amp to the battery? that is perfectly fine. Or grounding battery with 4/0?

    Run the 2 ground wires to the battrie then the 4/0 to the frame then a nice big 3 upfront with the new knuconceptz 0 gauge

    Yes, running a frame ground in the back, close to the battery, would be the way I would recommend you do it. As I said, 4/0 isn't necessary, just two equal lengths of that knu you already have, grounded to one spot, is perfect. That 100 feet will be plenty if you do it this way. If you are around 15 volts, with 5000 watts, then-
    current(amps)=power(watts) divided by voltage(vdc)
    so:5000/15= about 333 max amps you could be drawing from that particular system.
    having 4/0 wire that will handle 1200 amps of current will certainly work, but is, obviously, not necessary.
