    Hi I installed a new head unit which was working perfectly, however now it will not power up, I removed the head unit to check for touching wires etc and installed the old oem stereo to check if it worked, but that does not power up either. I have checked fuses 15 16 24 26 31 35 under the dash and also 38 and 44 in the engine bay.

    None of the fuses seem blown, I was wondering if there are other fuses I should check?

    The 12v accessory and usb charging still work, its only the stereo that doesnt power on.

    Any help would be appreciated.

    Is it a replacement JBL? If so, had it broken? Or something else?

    This likely means that two wires touched each other or a piece of metal behind the stereo. Make sure you are making your connections with something secure and that you cut any wires that aren't connected leaving no metal exposed. I like to use these https://www.crutchfield.com/p_669PP500/Posi-Products-Car-Stereo-Wiring-Harness-Connectors.html?omnews=15085713 since they leave no wire exposed and are very strong, even to terminate unused wires.
