    New Hertz Build, but 9 wire question

    Need a little info. My Ram Forum is a little limited with audiophiles so I wanterd to check with you guys. I have built and installed a few systems, but due to life and kids it has been about a dozen years since I built my last one. I purchased the following, but they said to install it with a 9 line wiring of which I have never done. Here is what I have and would appreciate any input:

    2012 Ram 1500 Cew Cab
    Non-Alpine System
    Factory RES Head Unit (keeping for now)

    Purchased the following to replace exisiting:
    Hertz HCX-165.4 (Rears)
    Hertz HSK-165.4 2-way (Fronts)
    Alpine MRX-F30 4 CH Amp
    Dynomat for doors
    9 Conductor Speed wire
    8 gauge Amp wiring kit
    LOC wiring harness (bought before when I had planned on only adding a sub)

    My question is, Do I use the LOC harness to tap into the wiring harness so as to avoid taping into the actual factory wiring harness? Or am I missing something?
    My plan is to install the tweeters in place of the 3.5 in the dash.

    Thanks,
    Brian

    will this work with your specific HU?

    otherwise, you can tap the factory harness at either the amplifier or the speaker, for the LOC. you need to find your factory amplifier. sadly, wire pin-out will be difficult to find, maybe your Ram forum is good for schematics and wiring diagrams?

    your plan for speakers is good. you'll need to make custom mounting adapters out of wood, no biggie, just waterproof them.

    i'm not familiar with the term "9 conductor speed wire"



    have you been helped by me? i'd love to know. shoot me a PM.

    Not quite that small. (each stand is 18-22ish) At best buy (lol), it's used for 4 channel installs. They run signal to amps via RCAs, then connect speed wire to the outputs of the amp (it will be the standard HU colors -green, purple, gray, white), back up front and tap into the harness to get signal to the speakers that way. They don't run new wire to the speakers. The blue remote wire is also in that casing to run back.

    its usually 8 speaker wires like the back of the radio green, white, purple, and grey and an amp turn in. it was popular for installing radios in older cars where the harness had to be run to the back of the car.

    its usually like 18-22guage and can easily hold 75w

    i personally use it when i run a processor to a factory radio. i just run 1 9wire and power and ground and put my processor where i want it rather than right behind the radio

    Re: New Hertz Build, but 9 wire question

    Keep_Hope_Alive:

    It does not have the factory amp. Only runs off the HU. I figured if I used the LOC to tap into, then I would avoid tapping the factory harness. I don't like the idea of tapping into the harness. I plan on running new speaker wire from the amp to the speakers/crossovers and just sealing off the factory ones for later use if I remove the speakers.
    As for speaker brackets I have a sheet of stainless steel that I will manufacture brackets from and then will put a rubberized coating on the brackets prior to install to reduce vibrations.

    you are going to have to tap the factory line somewhere a few t-taps behind the radio isnt going to hurt anything

    and thats going to be some expensive speakers adapters

    Re: New Hertz Build, but 9 wire question

    i prefer tapping with solder and heat shrink.

    i couldn't find harnesses that are into car and into radio (usually Metra 70- and 71-) that is my preferred method of intercepting wire behind the HU without cutting/tapping.



    have you been helped by me? i'd love to know. shoot me a PM.

    The sheet of stainless steel has been sitting around for about 4-5 years and it was free. I can now put it to good use and get it out of the shop.

    Re: New Hertz Build, but 9 wire question

    Completed the initial phase of the install. The Hertz speakers are very clear, bright and produce a great soundstage. Am adding the 10" Infinity Kappa sub to be powered by an Alpine MRF-50 (300 RMS). Swapping out HU at the same time. Thanks for all the info.
