How to Break In a Subwoofer For Your Car

If you have frequently visited any of the popular car audio forums, you'll notice that this question "how to break in a subwoofer" comes up quite a bit. So, is it real or just a myth? Let's find out.

Breaking in a subwoofer is a matter of serious debate in the car audio enthusiast community.

Some insist that it's absolutely necessary while others say it's not. However, a rough consensus has evolved that it's a good idea to consider breaking in subwoofers that are designed for for high-power operation.

That's because these subwoofers are designed and are built with stiff internal components - the mechanical parts such as the spider, the woofer and the rubber surround will be really stiff in newer subs - thereby, they require some break-in time before optimal performance is achieved.

Additionally, and from personal experience of over 15 years of experience in the car audio industry, subwoofers that underwent a break-in period of time tend to last a bit longer than those that are pushed to hit really hard out of the box.

How to properly break in your subwoofer

Breaking in a subwoofer properly takes time. I'd say at least a few of days, during which time the performance will change and eventually stabilize.

So, after you've had your subwoofer mounted in the right size enclosure and supplied with enough power from your amplifier, play some heavy continuous-bass music at a medium or low volume for a couple of hours each day.

It's highly-recommended to have a steady load on your subwoofer during the break-in period. Bear in mind that music tracks with sporadic or intermittent bass won’t do the trick.

So once your subwoofer has been playing for a few hours, you can push it a little bit, but not too hard. Keep doing this each day until you feel that your sub's cone and rubber surround aren't stiff anymore. Now you can go ahead and crank your subwoofer and enjoy that heavy bass!
