It’s a constant concern for those who invest in high-quality car speakers that, at some point, the speakers might blow out. Sometimes, especially if the speakers are old and dry-rotted, the passage of time can do that. Other times, it’s far more avoidable.
In Your Grill
While there are some speakers that have a cone-like cover sitting over the actual speaker cone, the most common covering for speakers is a grill cover. If this cover comes loose or falls off, particularly on door-mounted speakers, there’s a chance an errant foot could come in at the wrong angle and damage the speaker. It may technically be “kicked in” rather than “blown out,” but it’s non-functional either way.
Gains And Losses
It should firmly be fixed in the mind of anybody with an aftermarket car speaker installation that there is a difference between the gain on an amplifier and the volume control on the head unit. The latter turns up the sound coming through the speakers; the former turns up power going into the speakers. Too much power to the speakers causes audio clipping and distortion, which causes the speaker cones to stop suddenly then start back up. Much like sudden stops and starts will ruin a car’s brakes, audio clipping will quickly ruin speakers, resulting in a melted voice coil.
Keeping the gain down doesn’t mean the volume can be cranked all the way up and kept there without harmful effects. Volume should always be kept at a moderate level that lets you hear the music, but doesn’t necessarily cause the windows to rattle. We’re not saying that cranking it up for a favorite song once in a while is going to wreck the speakers, but moderation is key to getting maximum use and longevity out of them. Hey, you don’t drive at red line RPM’s all the time right?
What does a person do when they start up their morning drive mix and find their car speakers not working? It’s important to first figure out how they’re not working. If there’s no sound at all, turn up the volume for a few moments and listen to see if there’s truly nothing (indicating no power), or if there’s at least a little hum (indicating no signal). If there’s sound coming through, does it sound muted or distorted? Have any settings been changed on the amp or head unit? Does the head unit say anything like “check wiring” or “protect”?
