    Alpine 9847r cutting out!

    my headunits fine untill i crank it, when i turn it up above 20, it turns off then back again, when it comes on again the volume is at 0 or 1, it happens with nearly every song , not just the bassy ones


    any ideas?

    the head unit goes off, the backlights flicker a bit, then it turns back on

    is it possible that would be causing it?

    where are you taking the power feed from, its possible when your turning it up its drawing too much current and cutting out

    i have the same problem with my alpine cda9835r as said before how is it wired in? Have you used a direct feed to the battery and the same gauge cable for the earth? I found that when i used a separate amp to power the speakers i can go as loud as i like without it cutting out but when powering the speakers from the headunit, i'd get the cutting out above 20.

    the speakers are run on the built in amp, the amp for the sub is wired directly to the battery,


    the "loud mode" on my alpine is set to on tho, i'l try and crank it tomorow without the sub on to see if the same happens with just the speakers

    Its a case of, the internal amp on the headunit trying to draw more current that the wiring will allow. It switches itself off to prevent damaging itself. If you amp one set of speakers or both it will eliminate this problem! Thats how i solved it anyway! That or upgrade the headunit's wiring to a thicker gauge and take a feed directly from the battery, but if you do this remember to fuse the power cable and use the same gauge earth.
