do speaker wires go bad?

The cable themselves will not go bad. Yes copper will oxidize and this can cause more resistance at the connection point. Clean the connection points off so you have nice clean fresh looking copper, or just strip back new exposed conductor and you will be just fine.

As I said above, the insulation will degrade over time, possible to the point of allowing electricity to leak out of the coil. When the coil gets wet, or there is moisture near it, there is enough of a path for some (or all) of the spark energy to get out right through the insulation.

Yes, some tubes fail much earlier than that, but many indeed last that long. ... Preamp tubes are more compact and don't have to work as hard, so they tend to last even longer, or seemingly forever if you've been waiting for them to go bad so you don't need any excuses to try a new set.

Well, an optical cable won't "go bad" in the sense of wearing out or corroding, but it can break, which has pretty much the same result. Such a cable is little more than a bundle of glass or plastic fibres and if you bend one of them too far, it snaps like a piece of vermicelli.

Bozaks are pretty good. They hit the mark with other quality speakers of that vintage. They can be helped with some renovation and made better.

Most speakers are rated at 4, 6 or 8 ohms, and cheaper receivers can sometime have issues driving low-impedance (namely 4 ohm) speakers.

Mica capacitors very rarely go bad, and if you replace them, it will throw off the radio's tuning. Replacing the mica capacitors will do more harm than good. Replace a mica only if you are sure it is bad.

This is a sign that the amp is being overtaxed by a subwoofer or other speakers to the point where it simply can't provide enough power. ... If you find that the amp has plenty of power for the application, then there could be a problem with your speaker wires, the speakers themselves, or the amplifier's ground.

When using more than one speaker with your amp the equivalent overall impedance changes depending on how the speakers are wired. You can wire multiple speakers "in series," "in parallel" or in a combination of the two wiring configurations ("series/parallel").

An installation that is more than 10 years old will probably have worn out cables. The aerial. The aerial itself could be causing your bad reception. If it is old, it may be corroded and parts of it could be missing, causing poor performance.

if ALL the speakers are wired backwards, it might never sound its best, but if one is wired out of phase, the image will be like surround sound... sound will kind of come from everywhere and you'll have no centerpoint. Also, the bass will be really thin.

Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine.

Entropy, corrosion, manufacturing defects, critters, jiggling and vibration. Eventually all complex systems develop faults. ... Of course it is much more likely to be any of the more complicated parts of the system, but since you specifically asked about cable splitters, sure. They can go bad.

The brand is particularly known for providing decent wall and ceiling speakers at an affordable price. I wouldn't say that the quality is the best, but you get your money's worth so I personally wouldn't complain. These speakers are great for high frequencies and generally do a pretty good job.

Nonetheless, you should replace the wire (if possible) or replace the headphones, if they are hard-wired. Bare wires, regardless of voltage, can spark. ... While the voltage from the headphones is not particularly hazardous, a fire caused by them could result in grievous bodily injury or death.

It does make a difference depending on amp & speakers whether its better or not is open to debate. At the low end a better quality speaker cable with decent jumper bars is more worthwhile. The whole thing is system dependent as some speakers/cable/amp combos dont like it and some do. Bi amping is always worth it.
