Gemsound pa 1005 exa keeps shutting off

The gemsound is an amplifier

What model is the Onkyo?

Thanks

if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.

You could check the 115/230 switch. If you are getting power to the unit no fuse or circuit breakers tripped, and you have 8 ohm speakers connected, and a signal in you should get a signal out. Level controls should be up. If all of those things are true, then the amp is broke and needs an electronic technician to repair it.

check the rca's for a short

Hi...
If it's a straight-up power switch then it will need to be replaced if it works off a relay then the relay is gone.

Dc problem in amplifier (short circuit) needs to be serviced

First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.

Contact Gemsound thru their email.

please confirm from your speakers cables in good condition and from your speakers.make maintenance to your amp by air blower-clean air filter-keep good ventilation around.after cleaning and good ventilation make test with any media while you are connecting one speaker only and then connect the other one.

you sure you didnt flip the bridge switch on the back? its the tiny little black switch under the bridge output plug, if you have it set to "bridged mode" any input sent into the right channel produces only a hum, only left channel input works.
