S13 - Strange problem with Radio... electrical?

[Danrc30]

When I turn the volume on my Sony stereo up, it will shut off, and then usually turn back on all by itself. Sometimes it will stay off until I manually reset it. I basically can't turn it up too loud or it shuts off. The AM/FM also stopped working all of a sudden on its own one day while driving. I replaced the head unit, and it worked after I installed it. But the next day in the am, the same thing happened. Anyone know what's going on here?

Nobody has a clue?

Since the problem followed over to the new radio, you may be having a grounding issue. I would check all the ground points from your radio and make sure the antennae connector is plugged in all the way.

that for sure is a ground problem cause the harness for the nissans for the s13shas a ground wire but theres no wire on the car side of harness....add a ground and it will go away.....

Where do you recommend the best place to add a ground?

hey buddy you know what is the problem with your car radio when you turn the vol up it dies or stop, we call it clipping it clips every time the unit or the speaker cannot tolerate/handle the power that you are sending to the speaker it is your radio protection to both unit either to your sp/ rad. all you have to do is check your car stereo power output vs your speaker handling power and your wiring connections to the speaker it should be always in (+ to +) and (- to - ) forward bias if one or two of them are in reverse bias thats another factor of clipping ie if your car stereo is sensitive when it comes to connections . email me if you have any [email protected]

Hi. I don't think it's "clipping". Clipping doesn't make the radio shut off, and the volume level I'm talking about is at a VERY low volume... and I have good Polk speakers... also, the stereo used to work PERFECTLY! Then one day, this...

Thoughts?

looks like radio itself. try to connect it to another car or whatever, see whats happening. i had one that worked only when muted, some chip burned or something. also sony.

I thought it was the radio too, but I put a fresh one in (same exact model) and the same thing happened to it. I think something in the car is frying the radio part of the head unit... and the power shutting off it also part of it... but how can this be?

[ard]

you put another radio in, and it fried? try those radios on other cars, what will they do.it seems that you get a short circuit somewhere, take a voltmeter and check all your wiring at connection plug.

ok heres what your going to do remove all the power thats is connected your unit and run a fresh b+ if you can get it to main fuse line or other bigger wires that is a good power lines, and i assume that you know how to wire a RELAY and connect the out put of the relay to the switch supply of your unit not sure if its yellow or orange then try to fire it start at min vol for about 1 min. then start to vol it high slowly if the problem still exist try to use the fader set it to front sp. or rear sp. or if you are not lazy remove all the sp. connections and rewire it again one at a time make sure the polarity of the sp is in the right position, it seems like your car st. is so sensitive then vol it high slowly if the unit runs normal go ahead connect the remaining speaker wires (if the problem came out there you solve the proble) may be you are having a BAD WIRINGS)if the unit runs good go ahead wire the remaining sp.while unit is running in low vol but be careful for the wires to short with each other. i would suggest if you start in front sp. do the left and right sp. connection then the rear left and right or vise versa.good luck

noted get a good neg line too....
