Question about Onkyo Audio Players & Recorders
Hi Ryan, It could be that there is a frayed speaker wire touching the back of the receiver and when playing at a low level the speakers do not require that much power, however when the level from the speakers increases more power is required and if there is a frayed speaker wire touching the back of the receiver there could be a short causing the receiver to shut down. A way to avoid the frayed wire is to use "Banana Connectors" that the speaker wires goes to and the connector will plug into the speaker posts. Please try the following to see where the issue is coming from. Have the receiver turned off, make sure all the speaker wires are labeled, and disconnect them from the speaker terminals. Turn the receiver on select a source that would give you sound if the speakers where still connected and turn the volume all the way up. If the receiver shuts down than it would need to go to a service center as it is an internal problem with it. If the receiver does not shut down, turn the volume down, shut the receiver off and connect one speaker and than turn the receiver on selecting the same source as before and raising the volume up. If the receiver shuts down, remove that speaker from the post and connect it to another speaker post to determine if it is the receiver or the speaker itself that is giving you the problem. If the receiver should shut down after moving that speaker you know it is a problem with the speaker or the wiring. If the receiver does not shut down, turn the volume down, shut the receiver off and connect another speaker followed by doing the previous test procedure. Keep adding speakers until you have them all reconnected to the receiver as long as it has not shut off while trying the test procedure. After determining whether it is the speakers or the receiver you would need to bring either to a service center to be repaired.

The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.
The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.
If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.
Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.
To obtain service, take or ship your Onkyo product to an Onkyo Authorized Service Center. Please also include in any mailing a contact name, address and telephone number. Please include a copy of the original sales receipt/invoice as well as a letter stating what the problem is, with your name address and phone number so the service center knows who to return the unit to. Please note, before shipping, you must contact the authorized service center to inform them that you will be sending your unit in for repair.
