Your speakers are way tp powerful you should only use speakers just over what the amp is rated at the most and check your impedance is not lower then 6 ohms and turn the bass to half way i am using 60 watt bookcase psb speakers and they work just fine and they pound no problem

My Mp3 Player is Completely Dead And It Wont Turn On Am i Supposed To Leave It Charge


If it doesn't turn on, even when plugged into power, try replacing the power cable (usually a USB cable of some sort). If still not powering up when externally powered, then it is more than likly dead.

Subwoofer ain't doing anything on peavey triflex


Could be a few issues. If it is powered up when you plug it in, it might have a short circuit protection that shuts it down, or a thermal overload that is over sensitive. It might also be an issue with the cable you are using to connect it, from a broken wire to one that has a plug just slightly too long- there are 5 different tip lengths.

This also assumes the input itself is not being over driven, and that the output is not shorting out either..

Raised volume cuts sound and gives me "overload" message


A couple of possibilities: Bad solder on power regulators (attached to main heat sink) or cooling fan may not be turning on when volume is raised.

SA HE200 ~ Overload at power up


First of, be sure volume is turned all the way down before or as you are powering it it.
Second if that does not work disconnect all speaker, and input/outputs.  Power the device on and see if it says overload.
If it does skip the rest of these steps, your capacitors are bad or the power supply is no longer functioning correctly.
If it doesnt, start with testing each speaker at power up.  Match the speaker to the output it goes on, power the device see if it says it. 
If it does on any speaker test it is a speaker issue or a terminal issue.  To test for terminal or speaker issue plug a different/ known to work speaker in that same terminal, if it doesnt say overload it is a speaker issue, if it does say overload it is a terminal issue.
Once you have made sure all speakers and terminals work correctly start plugging input and outputs in and test individually.

Technics SA-DA10 jumps into overload after 10 minutes


Have you tried connecting speakers? What was the result?

Yes, when you turn the volume up on these amps (or when the output gets past a certain level) the cooling fan should automatically come on.

PROTECTION MODE


The unit may be experiencing an overload caused by a short circuit, internally or externally. Try disconnecting all the speakers, then turning up the volume. If nothing happens, connect one speaker at a time and turn up the volume to see if you get more sound. You may have a speaker that has shorted internally and this will help you discover the bad one. However, if when you have all the speakers disconnected, and the unit still goes into protection mode with the volume up, then there is a problem with the unit itself.

Hope this helps, and please rate my advice, good OR bad.

Good luck!
