How can you tell if a speaker is bad?

Measuring them with a multimeter will often give you results that could make you think the speaker is bad. The best way to test them is to QUIETLY play a signal through them, listen to it, then see if it produces sound. If it does not, or sounds bad, the speaker needs replacing.

How long do speakers typically last?

Most speakers last more than 20 years, but some can last a lifetime. It depends on many factors, the most important among which are the type of the speakers and their maintenance.

Do speakers wear out over time?

Short answer, yes. Speakers do wear out over an extended period of usage. Speaker parts such as the surround, cone, capacitor in the crossover, and ferrofluid in some tweeters degrade over time, and that reduces the overall sound quality of the speakers.

How do you check for a blown speaker?

Physically inspect the speaker. A blown speaker can have damage that can be heard with some mechanical movement. If you gently tap on the cone of the speaker it should have a firm drum like sound. If you hear a rattling sound (like a loose snare drum), this is an indicator of a bad speaker.

Does a blown speaker rattle?

Sometimes a blown car speaker may still transmit sound, but it will give off a rattling or popping noise. This may mean you need to replace the speaker, or it could point to a minor problem, such as a broken tweeter.

When should you replace speakers?

Providing you look after them, speakers often last for 10-20 years before they need replacing. With so many different speaker types available, there’s a lot of variation in terms of quality, durability, and longevity.

What can go wrong with speakers?

The speaker can blow an electrical or thermal fuse. Wiring can be faulty. The voice coil can be faulty, a speaker can be blown, a crossover network can be faulty, or a solder connection can be faulty. Cables and connections can be faulty; a driver cone can be damaged.

How do I know if my speakers are blown or not?

If you can only hear rattling, the speaker is well blown. Damaged tweeters cause a popping sound. Incomplete system range – your speaker may not be full-blown if you have an incomplete range. For instance, if the bass or high frequencies are low or missing, the speakers are at least partially blown.

Why is my speaker making a popping noise?

It could be problematic wire, but it may also be a blown speaker. Popping and rattling noises – apart from the classic fuzz, there are a few other signals that will underline an issue. If you can only hear rattling, the speaker is well blown. Damaged tweeters cause a popping sound.

How do I troubleshoot a speaker?

One of the best ways to troubleshoot a speaker is to check the speaker’s impedance (resistance) with a multimeter. Speakers always come with a certain impedance rating. Common values of speaker impedances are 4Ω, 8Ω, 16Ω, and 32Ω. The impedance rating is usually specified on the back of the speaker.

Why won’t my car speakers turn on?

When you get in your vehicle you expect to be able to turn it on and your favorite station or CD will start like it always does and sound good. If it doesn’t go on or if what you hear is different than usual (in a bad way), maybe you have a blown or partially blown car speaker.
