Loud buzzing when turn on, no input signal


put a song onto play using either tape, vinyl, cd or mp3.

once playing follow the wires from the speaker that doesn't work bending it until you hear it crack or become clear if it does either of those it is the wire between the head unit and the output.

if not you can try attaching the speakers to a different head unit if it doenst work it could be the driver (the cone doesn't have to go to blow a speaker)

Jensen QX-80 keeps cutting out even when on low volume. Have tested another SW and that worked fine so leads, speaker amp ok. Tried audio out from blue ray and same problem, the other SW was fine, the QX...


If I understand you, you're observing the speaker cone moving in one direction without any input. That would say the internal amp is malfunctioning and pushing DC to the speaker. Beyond that I can't say, but it is endangering the driver.

Hello
Your speakers' lead wire has a break in it. Lead wire is one that goes to the speker paper cone, from the connection point. It is a brided copper wire, very thin and flexible. If you be carefull, you can repair it. Speaker lead wire can be bought from electronic spare part shops. Just find out the size use in your speaker, buy a short lenth of it, say half a meter or so [even though it needs a few centimeters]. Look on the spekares leadwire fittings; you can compare the fittings of the other leadwire, and replace it. It is a very keen and sensitive work. After replacing the wire, fix it with some sort of rubber based gum. That is all. OK.

I put a new speaker in my amp but don't know what wire is positive the blue or the yellow


Usually the yellow will be positive... Hint, it won't make a difference UNLESS you drive two of these in parallel as it only affects the phase of the cone movement relative to the input.

Connect the yellow to positive and don't worry about it further.

When I push my subwoofer cone its work and when i release it stops working. how can i fix this speaker? the make of this is 12'' 1210 Watts Infinity sub.


Looks like a broken copper braid that links the speaker terminal to the cone (from there on it goes to the coil which is underneath the cone).

Check the speaker connection terminals (near the magnet), you will notice that each terminal has a copper braid wire going from that terminal to the speaker cone.

Inspect both braid wires carefully at each end (near the speaker terminal and near the speaker cone), there will either be some damage to the braid at one or more of these four locations or the braid could be actually broken at any of these spots.

The braid can actually be resoldered at the point where it's damaged or broken - this task will require good soldering skills, mainly because this kind of braid wires are difficuld to solder (they are a bit difficult to clean because of their structure and solder won't attach itself well to oxydized copper), but also because some speaker cones are made of plastic which may melt if you overheat it with a soldering iron.

Besides that, when resoldering is being done, only a very short portion of the braid should be wetted with solder because the solder point will become rigid when the solder cools down, and the braid needs to remain very flexible when the speaker operates (if it's too rigid or too short, damage to the speaker cone could occur or the braid could get broken again when the speaker will be playing at a loud volume).

Hope you can have it repaired, it can be done at home, but there are also speaker repair shops where you can get it done (i'm not sure about the prices though).

Anyway, the alternative is to replace the speaker itself.

Speaker aint hitting like it should and i smell something burning from the speaker what could this be and how can i fix it


sounds like you are frying the voice coil! Push the centre of the cone in and if you hear a crackle then time to buy new speakers.. sounds like they are on way out if you can smell burning!
