The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

Here are a couple of common causes for this... You may indeed have a wiring issue between the receiver and speaker(s) - i.e. wire damage causing the conductors to touch each other (look for wire problems at the back of the receiver or speaker(s) right where the wire connects to the device). Also check for physical damage like pinched wire, damaged or missing insulation, etc. The speaker(s) could be damaged (possibly from excessive power/volume levels). If these are not the problem, the cause may be the receiver itself. Try disconnecting one speaker at a time and running the volume back up to see if the receiver shuts off. This may help isolate a specific wire/speaker to check.
The unit is protecting itself from a high current situation on the output amps. Either you have a bad speaker or an Amp that is getting ready to give up the ghost. Check your speakers with an Ohm-meter for proper readings (ie 4Ohm speaker should read 4 ohms)
Speaker Impedance:
When speaker systems A and B are used separately, speakers with an impedance of 6 to 16 ohms can be connected for use as front speakers
Be careful when using two pairs of front speakers (A + B) at the same time if their impedance is less than 12 ohms.
The protector circuit may be activated of the set is played for long periods of time at high volumes with an impedance lower than specified are connected.
check your ground, it could be that your antenna is the only source of ground, in which case the deck does not have enough power to stay on when it draws too much power. I've seen exactly what you are saying many many times. Ground it really reallly good.
