    12v+ drop

    Where have most ofyou ran your 12v+ drop from your battery? down the middle? under the trim? under the car(yes i know this is a bad idea just fgure I would include it) ... to get to the rear oc your vehicle.

    I think it's going to really depend on the vehicle; some it would be easier to run it along the bottom of the car on the outside, but the best option would be to route it inside the car, more than likely down one of the sides hiding it behind paneling

    in my last dual battery install on a pickup truck where I installed a second Optima battery in a tool box in the back of the truck to power an air compressor and AC converter, I kind of ran it both ways; 2ga wire under the hood, through the firewall, through the cab, out the back/bottom of the cab, up between the bed and the cab, then through the bed and then through/into the tool box. ideally, try to keep it out of the weather and far from heat or anything combustible (like fuel lines). biggest thing is don't forget to fuse it at the battery!

    I ran mine on the opposite side of the truck from the audio cables.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    In my honda civic, I ran the wire in through the drivers side firewall-access hole. Then the wire turns and goes directly up the middle of the car (underneath the center console). I did this because there is much more room under the shifter and such than there is under the side paneling. The gauge of the wire is 0 so it does not fit nicely anywhere but here. Now the only place the wire is visible is right before the back seats. Other wires going with the power wire include the power wires for pc, screen, and remote turn-on for amps. My rca cable is on the right side of the car and the distance between the two has not caused any interference as of yet.

    I definatly want to run a different direction than the audio wires...I know it makes for noise...I am wonding if I can fit a 2 gauge under my door trim...worried if I it down the middle it will make a bump in the carpet

    Really depends on the car and wire. 2 gauge is going to be harder to conceal. Definitely away from audio wires. Typically the sides are good. I don't think I have ever run power down the middle. I wouldn't run it under the car. I have never seen a manufacturer run wires under the car so there is probably a good reason for that. I also remember how my under car lights (yes I know... leave me alone) wires would inevitably get snipped on the hoist every year for inspection and pulled off with ice every winter.

    As i ponder which cable to drop...I wonder if it would be etter to run a couple 4gauge and hook together on each end sl they act as "1" wire...or 1 2 gauge

    I didn't really buy any "kit", I bought the wire from a local shop and put things together myself.

    And I think you'd be better off just running 1 single larger cable. You want as few points as failure or issues as possible. Doubling your cables essentially doubles your points of failure or possible issues. I couldn't say with any confidence if it would perform any better or worse using the multiple cable method, but it seems like it would just be more hassle then simply running one singe cable.
