    Default System Wiring Diagram

    Guys,

    I have been doing alot of reading here. There is a treasure of information and I have learned a ton. Based on what I have learned, I have created a diagram detailing how I feel that the stereo system I am considering should be installed. Please take a look at the wiring diagram and wire sizes and let me know how it looks.

    Any help is appreciated.

    Wire Sizes:
    Cabin / Bow Speakers - Factory Wiring (Not Sure of Gauge)
    Tower Speakers (16 Gauge Through the Tower but could use to Feed Larger Wire)
    Battery to Distribution Block - 0/1 Gauge
    Distribution Block to Amps - 4 Gauge
    Amp Ground to Distribution Block - 4 Gauge
    Distribution Block to Battery - 0/1 Gauge

    Stereo Items:
    3 Pairs SX65
    2 Pairs of either XM7 or SXT65
    800.4
    Harpoon
    JL 10W3
    RF Punch 201s

    It looks like you have a ground distro and a power distro? They make distribution blocks that do both of these task if you want to save the space.

    I can't comment on the Exile tower setup but I ran mine the same way i did the cabins (in parallel). But that may be right for the exile setup because i know they use a different amp.

    When Dusty and I did our install, it was recommend we use 12 awg to HLCD's.

    The boat already has these separate so I will continue to use these.

    I believe (could be wrong) that this tower wiring configuration will allow me to only run half the wires up the tower.

    I thought that this wire was too small.

    Trying to decide if its worth it or not. Current mentality is based of my home stereo; buy nice stuff once and keep it for a long time.

    12 awg is larger than 16 awg.

    I get what you mean on running half the wires up the tower. I jumped from one speaker to the other (in parallel instead of series). Connecting the + to + of other speaker and from - to -.

    I could be giving out wrong advice here though because i am not familar with the Exile setup (harpoon?). I will let someone else comment on the tower wiring.

    As shown, you've got the tower speakers wired in series, presenting an 8 ohm load to the amp and consequently, delivering significantly less power to the speakers than if wired in parallel. To wire them in parallel, you need to connect the negative terminals together, and the positive terminals together. Then connect the negative from the amp to the negative of one speaker, and the positive from the amp to the positive of the other speaker. This way, your speakers are wired in parallel and each speaker will get 250W rms from the harpoon.

    See the link below for an in depth explanation on series vs parallel speaker wiring:

    bhowell,
    Yes, four conductors of 12-gauge up the tower will facilitate any four (two pair) of tower speakers that you intend to run. As mentioned above, you will jumper or parallel the speakers at the top when you are using a two-channel amplifier.

    my fault bhowell, i thought you were meaning you thought the 12 awg was too small.

    Cab and David covered what I was trying to say about wiring in parallel, and they did it with much more confidence. Ha!
