It’s better to overpower a speaker than to underpower it — the distortion caused when you push a low-powered amp or receiver to its limit is much more likely to harm a speaker than too much power. … Low-efficiency speakers can sound great, but they’ll need a high-powered receiver or amplifier for energy.

Are vintage speakers better than new?

No, but there is a lot to say about many things of older speakers. They’re not better simply because they were made to be powered from weaker amplifiers (in general), so they have higher sensitivity, but this usually sacrifices quality somewhere.

What would cause speakers to stop working?

When all of the speakers in a car audio system all stop working at once, the problem is usually in the head unit, in the amp, or in the wiring.

Will a blown speaker make any sound?

If a speaker is completely blown, it will likely not produce any sound and may just make a soft hissing or ringing sound instead. … Therefore, you should listen to the speaker at a range of different volumes to determine if the distortion remains constant or if it seems to worsen.

How do I stop my speakers from blowing?

Keep the volume on your receiver at least 5-6dB below its max setting. The volume adjustment on most receivers goes from -80dB (mute) to about +16dB (max). By staying below -6dB below that max setting you can typically avoid over-driving the receiver, which could potentially damage your speakers and receiver.
