The sub could be shorted or the wire connections of the sub could be shorted, or there could be an internal problem with the amplifier such as a shorted output stage or failure of some other component(s)
The DSW ProSub is a nice amplified sub. The reason it is shutting down is the amp is being worked to hard and it's going into thermal mode and after you turn down the volume and it cools down it's coming back on. To much of this and you will have a nice sub and no amp to run it.
One thing to do is keep the sub/amp in a well ventilated are and put a fan on it if you can to help move the heat away from the unit.
The amp is rated at 250 watts so if you push it to hard it's gonna keep shutting down. So turn it down a little so it runs longer and smoother or add another sub to the set up if you need it louder (like we all like). One sub can only do so much.
Also make sure if the receiver your using has a base setting or an EQ that you keep them levels set a little lower. Most receivers and home theaters already have an amp in them and you don't want to run to much of that into another amp. It's over kill. Find that happy medium.
If you have any questions or comments please feel free to ask.
You COULD run the Main speaker output to the large Red/Black speaker inputs, then some more wires Out from the other Red/Black connectors to your Main Speakers. That way your amp volume control will affect both equally.
Tweak the sub volume, crossover and phase to match it up to your mains.
phreewillie, If you are certain that the problem is not with the speaker(s) the problem then sounds like an issue before the amp.
Did your friend have this issue? If yes, the problem is with the built in amp/crossover. If no, there is some kind of problem in your location.
The amp will not produce the popping sound even if the the amp has a problem electronically. The problem could be improper voltage, line noise, wire resistance or a grounding issue. The first two would be eliminated by using a line conditiner with a built in surge protector. The resistance and grounding issues would be associated with the wire connecting the sub to your electronics. It could be simply the cable connecting the sub has an issue, try swapping it with one that you know works fine. Are you using in wall wiring? Try using like stated above, a short known good patch cable. Sometimes the wire of choice during a installation will not work for that amp. Try taking that in wall cable out of the loop. I have seen just this problem in the past due to the type of wire used. A low cost way to eliminate the voltage issues is to try a different source of electricity by taking the sub to a friends house and see if you can reproduce the problem there.
I HAVE 4 PS212 AND FROM WHAT YOU ARE DISCRIBING SOUNDS SIMILIAR TO WHAT HAPPENED TO ME. PLAYING THE SUB AT FULL VOLUME AND CLIPPING OCCURED NOT KNOWING THAT THE FAINT SMELL WAS THE VOICE COIL BURNING AND CONTINUING TO PLAY UNTIL KNOW SOUND LESSON LEARNED BUY A BIGGER SUB SYSTEM OR REPLACE YOUR SUB WOOFER.
IN MY OPPINION THIS IS A VERY GOOD PRODUCT WHICH I HAVE BEEN ABUSEING FOR MONTHS . SO QUIT WHINEING AND PAY YOUR DUES.
Does it only pop and crack when its connected to your amp or receiver ? i have the same thing with my sub [its not cerwin vega] but when i turn my amp off the sub doesnt pop anymore so i think my amp is the problem not the sub , yours might be the same problem .
The receiver automatic speaker set-up set the sub volume at -12 and since it was not getting any signals from the receiver it was doing what it is supposed to be doing (going to the standby mode). This was troubleshooted by Onkyo tech support on a Sunday. All the best about Onkyo customer support.
I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.
