  • Replacing speakers/amp on 2015 G23 CE - What is recommended with my current setup?

    1. Im replacing the interior speakers (stock installation) and an amp that is bad
    or potentially a whole new system if it make sense


    2. CURRENT SETUP

    2x tower JL 7.7 - MCS-77CCX5-4-TB (these were what was stock, and i already replaced them with 2 new ones of the same model)
    6x Polk mm651 interior speakers - these are pretty much shot after 4yrs salt water use)
    Polkaudio 10in sub (works fine)

    2 amps
    PA D4004.4
    PA D5005.5

    Head unit
    Polk PA450UM - works fine


    3. ISSUES

    a. i forget which amp works what, but one of the tower speakers always cuts out once the amp gets hot (speak is brand new). so i figured i need a new amp

    b. also currently the volume randomly changes constantly. and when i speed up, then reduce throttle, the sound goes way down. maybe a feature, but i dont want it.

    c. half the interior speaks arnt working or sound bad....salt corrosion setting in


    4. NEW SYSTEM NEEDS

    Im preferring to go all JL if possible
    ill install 6 new interior speakers, and a new amp (maybe more power?) that wont cut out
    might also get 2 more tower speakers installed if thats not too hard

    maybe i can bypass the console completely and just connect my phone with bluetooth to the head unit in the glove box? skip all the issues with the console and control it with my phone only

    The PAD400.4 should power the tower speakers. You can confirm by disconnecting a power cable, then power the system up and see which speakers no longer play.

      lots of things. what do you mean by console?

      JL m6 is the way to go, rgb is your choice.

      3x m6-650x, two bridged at 2 ohm for **** pit, bow as normal
      2x ETXv3-M6-770x
      JL sub if wanted, m6-10ib

      RCAs are could be your issue with the intermittent noise issues, grab a replacement RCA, see what changes. don't recall polk have Speed sensative volume but there are aftermarket options to add that feature, could be on your boat.

      the M6 speakers and subs are incredible.

        thanks!

        on the 2015 G23, the stereo control is integrated into the digital control center in front of the steering wheel. not sure if that is the part that is messed up or not.

        i dont have noise, i just get constant volume changes. i have to keep turning the volume back up.
