I have a car stereo with 4 speakers. When playing the stereo it cuts out completely at the same volume level each time. It will then come back on if I turn it down. What's the problem?

It is possible a self-protect feature may be shutting down output. Check all of your wiring, following the manufacturer's instructions exactly. Faulty wiring is a major cause of poofed audio output devices in car audio. Any short in wiring, or an open (intermittent or otherwise) can cause a problem here.
Internally, bad solder connections where the output devices solder to the board could cause problems too.

My electronics savvy source says you may be overdriving the amplifier in your Kenwood stereo to an impedance-mismatched set of speakers, meaning that the speakers are impedance mis-matched to the Kenwood stereo, and therefore operate ok (but inefficiently) at low volume, but cut off completely at higher volume. Fix: match the impedance of your speaker network to the specs on your Kenwood car stereo. Once this is done, you should be able to crank up the volume to the point of permanent hearing loss. SAFETY CAUTION - sound levels above 85 decibels produce NIHL (noise-induced hearing loss). http://www.dangerousdecibels.org/education/information-center/faq/
The tweeter is working but the woofer driver isn't which will change the impedance (ac resistance) of your amplifier output. The other speaker isn't working which will again, change the impedance even more. This could eventually damage the I.C. amps should you apply too much volume to the speakers. You can turn the volume up to normal listening level and with your finger, slightly press the cone on the woofer in and out a couple of time. Does it engage in sound when you do this? If so, the woofer's coil is damaged and the woofer must be replaced. No sound? Open up the speaker (stereo off) and make sure both wires are fully secured to the woofer. Should they be attached securely, your woofer is probably defective. Should you have a crossover network, you can obtain a good, known working woof and temporarily wire it where the old woofer goes, turn on your stereo (minimal volume) which can verify the network pcb (crossover) is working.

I had the same problem and found that when I moved the speakers apart further...It works as well as it always did before my 8 speakers were introduced..I think the sound was interfering with itself.. Try it !!
Could be caused by a circuit protection design built into your system. If you are playing your system at to high a level you could be over driving the amp, in order to protect the amp from frying, it has a circuit built into the design that shuts it down when it reaches a point where it could be damaged. Does the unit do this at all volume levels??
stereo is detecting a short , or low load on speaker wire and or speakers .Go behind car stereo , disconnect all speakers and apply a known good speaker to one of four wires and see if volume works normally ..If it works use same speaker on all outputs one by one ..If all are okay then you should figure out what speaker and or wires are causing issue..Also make sure your ground is okay
