Speaker sounds blown at any volume other than very low. Examination of speaker shows no tears, cuts, holes, etc. Speaker feels very lose where it expands. Speaker or capacitor?

first thing,,,,make sure the speaker wires are not touching each other.
i dont think it would be a fuse because that would cut the sound completely.you could open the unit to check for a fuse or fuses.
if none of the above help,then take the unit to a tech.i suspect a blown channel which means a capacitor needs to be replaced.one more thing...swap speakers over to make sure your speaker isnt blown

Well yes your speaker is damaged, the cone actually has a tear, so audio that has low base or high pitch will cause distoration..

Simply remove it, take it with you and buy a similar one.. Same size, same watts, same ohms and just put the new one in.

speakers are standered only brand names are different..

BTW if you feel that you dont want to purchase a new one, simply stick the tear with duct tape, or you can hot glue it together.. If its plasctic, plastic weld works good(ask for it at a hardware)..

Turn the volume knob below 3 before turning the unit on. If the volume was turned way up and then the unit turned on it may have blown the speaker protect circuit. It is designed to prevent blowing the speakers. They need to be powered up slowly to prevent tearing the cone.

Swap the speakers to see if it correlates.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Sounds like your sub is "clipping". Clipping is when your speaker is trying to pull more power than the power supply. (head unit, amp) If it sounds good at a low volume and choppy at high volume, supply it with more power. Bigger amp. If it sounds choppy all the time, push gently on the middle of the speaker. It should go back and forth smoothly. If it feels rough, you have blown the coil. Replacing the speaker is the fix for that.

Check connecting and Volume settings. Speakers might be blown. This happens when high volume is played and speaker tears causing a poping and crakling sound

Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.

It could be a power problem, unless you have blown the driver ?, carefully pull out the power supply board, and look to see if anything looks melted, burned, or capacitors popped etc. Be carefull though as I do not want to be responsible if you get an electric shock, etc. preferably look and dont touch, just use common sense ;)

i know what wrong i had the same problem see this black thing in the middle breaks from too much vibration

After I posted my problem, I browsed a bit further through the other posts and solutions, until I came across the solution of TrickyTrev34 and gave it a try. However, I did not slice the cable, but did it as follows: 1. Switch off power of the sound system on the subwoofer box. Disconnect the Front Right (FR) speaker box (the one with the volume control) from the subwoofer box.
2. Remove the silver coloured metal oval on which the speaker box stands. Now you'll see a small screw at the bottom of the speaker box. remove it. 3. Carefully remove the silver coloured metal protection plate (with all the little holes) from the front of the FR speaker box by wedging it from the top with a flathead screwdriver or other thin blunt object. Now you'll see the speaker and 4 holes with screws inside. Remove screws and speaker box opens up. 4. Inside you should see six wires (Red, Blue, Yellow, White, Green & Black). Carefully cut the GREEN wire only.
Insulate the both ends of the GREEN wire with electrical tape or heatshrink or similar.
5. Put the FR speaker box back together in reversed order. 6. Connect FR speaker back to the subwoofer box. Make sure the volume setting on your PC is very low, because when you switch back on the power of the subwoofer, you should be blasting again. As TrickyTrev34 already mentioned, the only downside of this procedure is that it will disable the volume control on the FR speaker, but who cares, your sound system works again, and you can still control the volume via the PC playback control panel and/or the multi-media keyboard if you have one.
