Help!! Stereo turns off when raising volume past 30/lights only work when headunit on

[fourstaroots]

ok, i installed a new JVC stereo into the 94 4runner, and now when i turn the volume up past 30, the stereo shuts off and resets! any ideas?... also, the top lights dont work and will only work when the headunit is turned on.

could this have to do with those stock amps i took out for the rear speakers?

anyone have any idea?

why do you turn the volume past 30? sounds like the radio is clipping like and amp, don't turn it past 30, or check the fuse behind the radio and the fuse in the fuse panel, is all your wiring legit? your lights must be wired to the radio wiring which get power when the unit is on
