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?

check your ground and gain on your amp

im not using any amps... its just the headunit and speakers

the problem might could be that your deck is not getting enough power, check your wiring to see if the connecter is tight

sounds like a ground problem to me. are you using the factory head unit or an after market? sometimes ive found that if you groung becomes disconnected or weak the head unit will power up with the ground from the antenna but its not strong enough to ground the unit when you turn it up. it would explain your problem. try to un plug the antenna and see if it powers up? if not then just re ground it.
