    Question Running cables from dash to under driver's seat

    I've got a DWW-700H mounted and ready to go, as well as a laptop car PSU spliced into the cigarette lighter. The power brick is inside my dash and has a long cable for the laptop.

    The problem I ran into was running cables to the carpc under the driver's seat. There's a wire conduit running on the bottom part of the door frame, but it's too shallow to fit anything but some speaker cables (which is what I have there now, in addition to the stock wire bundles).

    Running the cables underneath the carpet is a possibility, but the problem lies in getting through the "hump" underneath the front of the driver's seat. There are (at least) two hollow U-shaped reinforcement beams running the width of the car -- one under the front of the driver's seat and one behind. The front seats are mounted on these beams.
    There is also an air duct intersecting the beam.

    Is it safe to drill a hole in this beam and run my cables? I can't run the cables over it since the carpet will bulge. I'm worried about drilling because it may compromise the integrity of the reinforcement beam...

    I can provide some drawings to help explain what I'm talking about.

    We don't even know what kind of car you have.

    And as for running your power off your cigarette lighter, I will repost the same picture I made for another member "Maheriano".

    Trust me, I double checked everything. The amps have their own dedicated line straight off the battery. This isn't an electrical problem, it's a design problem.
    The car is a 2005 Hyundai Accent.

    Was my question confusing? Again, I can provide some drawings to clarify.

    Not the amp, but the PC. You are powering the PC off the cig lighter. THAT IS A NO NO!!!! I know the pic has an amp, but imagine a laptop. I can change it if it makes it work better for you.

    The question wasn't confusing, but we had no idea what car you had.

    I have no idea about your question, but I am sure someone will. I do however know that running your laptop off the cig line for prolonged times will result in your death.

    thankyou!

    Maheriano finally understood the dangers when that picture was first made. I believe it sticks in their brain!

    can you please clarify why is it bad to use ACC socket power for a laptop? It is the same voltage, already is fused, etc...

    Well I give you this homework. Take a look at the physical wire's connected to the cig lighter port. I can guarentee you that those wires are puny little things. Not meant for a PC. When you run large currents down small wires, it is like a torrent of water flowing through a tiny pipe. It will fail. Wire gets hot and burns i.e. smoke sparks and if you are unlucky, fire. Pipes just burst and get water everywhere, electrical overloads are no good.

    I understand that the wiring is high guage, but this should not affect a laptop install. My laptop, along with all the peripherals, takes ~70 watts. My cig lighter is rated to 120 continous. It works just fine, and has never blown the fuse.
