    Do I understand the wiring?

    I was wondering if you could look at this and try to make sense of it. Is it correct? This is what I gathered from reading a few threads on here. Anything I should change?

    Thanks, this will be my first venture into mobile electronics.

    I would appreciate it if you could help me determine the AWG of wires that should be used. I haven't found a clear post about that.

    Yes, thanks for the quick reply. I purposely didn't put those on there. The ground wires will just attach to the frame of the car wherever there is a convenient area to do so.

    Anything else or does that look right?


    How about the AWG of wires from the battery to the block and then from the block to the amps and pc? What AWG from the PSU to the screen? Thanks for helping.

    You need to figure the wattage of the system to determine the AWG. That being said, 6 gauge is usually a good bet. I'm running a very low power system on 8 gauge.

    To the PSU, I think the manual ought to say but most screens only pull an amp or so. 12 gauge should work fine.

    I don't know enough about amplifiers to help you there. www.the12volt.com is a good source of information.

    The gauge of the wire you use must be appropriate for the amperage and length of the wire. Without knowing more, a safe bet is at least 4 gauge from the battery to distro block, though 0 gauge would be better. And from the distro to the amps and pc should be about 8 gauge or better. Ground wires should be EQUAL to the power wire as far as gauge goes.

    These numbers can be changed depending on the amps power/amperage draw, and length of run, but that should get you started.

    P.S. THis is my 2 cents. Some might have other opinions.

    I have another question so I will just post it here in the same thread. I have a 1994 Ford Aspire. It is a small car. I don't know if the alternator and batter will be able to sustain my system. What are my options?

    If it drains the battery do I just get a high output alternator?

    I did a little reading on tank circuits, but did not fully understand them. Is this another option to solve this?

    Also, what is with these problems with cranking that I read about in the tank circuit threads? Would my setup have these problems?

    1. Look up the output of your alternator. That will give you an idea of whether it is up to the task. You should also estimate the power consumption of the system you intend to install.
    If it drains the battery do I just get a high output alternator?
    2. Not necessarily.
    I did a little reading on tank circuits, but did not fully understand them. Is this another option to solve this?
    3. No.

    4. Maybe.

    You should read this to get started:

    Then this.

    Ok, I shouldn't have problems with cranking because I will be using an Opus PSU. Why wouldn't another battery wired parallel solve that problem though? If two batteries are wired in parallel don't they drain slower making it easier for the alternator to charge them?
