Why do my subs keep blowing?
Subwoofers are most commonly blown by supplying too much signal to the car audio amplifier.
The result is a “clipped” signal and this can damage the amplifier and subwoofer.
A subwoofer can be heavily damaged by a sustained clipping.
You’ll know a clipping sub when it suddenly sounds very odd and loud..
How do I stop my subwoofer from popping?
Adjust the gain control on the subwoofer in conjunction with the bass level control in the receiver. You may find a combination of settings that maintain correct bass levels but reduce the annoying “pop” a bit. Check the Input settings for each input device.
How do I know if my tube amp is blown?
Crackling, squeals and feedback, excessive noise and muddiness or low output are all evidence of tube problems. Power tubes. The two main symptoms of a power tube problem are a blown fuse or a tube that begins to glow cherry red. Either are typically indicative of a power tube failure.
Why does my stereo turn off when I turn up the volume?
In many cases, premature shutoff of your unit can be caused by a problem with the speaker wiring between the receiver and speakers. A single strand of wire in the wrong place (causing a short circuit condition) will cause the unit to shut off at anything but very low volume levels.
Can a bad ground cause an amp to overheat?
A car amplifier can overheat for a variety of reasons. … Blown/grounded speaker(s), poor power and/or ground connections, too low impedance load, or gain/punch bass control settings too high, are also some of the most common reasons that can make an amplifier overheat.
Why does my subwoofer pop when I turn it off?
There is energy stored in the woofer (inductor) or in the capacitors of the amplifier, which causes a back-EMF when the circuit is cut, much like when you turn off a fluorescent light; sometimes you see a spark at the switch. Any transient tends to make its way to the speaker, causing a pop.
Why is my amp popping?
If you are referring to a “pop” when the amplifier is first turned on (or off), that would be the sudden inrush of current to the reservoir capacitors in the power supply. … Because the amp’s power supply is (briefly) shorted during this event, a “pop” will often be heard from it’s output.
Why does my amp turn off when I start my car?
A bad fuse, or any loose or poorly connected power or ground wires, can also cause an amp to turn on and off at random. … In situations like these, you may find that the head unit shuts off and comes back on when you start the car, but the amp doesn’t turn back on or never turns on at all.
Why does my amp go into protect mode when I turn it up?
If you find that one pair of speaker wires or one speaker causes the amp to go into protect, disconnect all speakers from the other end of the wires and separate the wires so they can’t touch. If the amp still goes into protect, you have a bad speaker wire or the wire is shorted to chassis ground.
What causes popping sound in subwoofer?
Pop: A clipped signal tries to move the cone too quickly Nothing travels that fast, and the sub either tears itself apart trying, or the flapping cone wobbles just enough to jam the coil in the magnet’s voice coil gap, killing the sub.
