How do you test a car subwoofer?
I’m not sure if my car’s subwoofer is working properly and I want to know if I need to return it. How do you test a car subwoofer?
Chloe Jenkins · Updated on
Reviewed by Shannon Martin, Licensed Insurance Agent.
To test your car’s subwoofer, you will need to purchase a multimeter from an auto shop or online.
To test your subwoofer using the multimeter, do the following:
- Start by disconnecting the subwoofer from any power sources and removing any connected inputs or cables.
- Take your subwoofer out and attach the positive multimeter probe to the positive terminal on your subwoofer and the same on the negative side.
- Turn on your multimeter and if you see a reading above 1.0 ohm, your subwoofer is in working condition. If you see anything else or nothing at all, your subwoofer is likely damaged.
If you’ve just purchased that subwoofer for your car, make sure to inform your
car insurance
company so that they can cover it under your policy. If this addition to your policy can’t be covered or causes your bill to increase, consider switching your car insurance with the Jerry
app.Once you download Jerry, just answer a handful of questions that will take you roughly 45 seconds to complete and you’ll immediately get car insurance quotes for coverage similar to your current plan. Jerry customers save an average of $879 a year!
