5 Ways How To Tell If A Car Subwoofer Is Blown?

Recently I was driving to work this morning when I heard a loud pop from the back of my car. I wasn’t sure what it was, but I knew it wasn’t good. 

When you hear a strange noise coming from your car, it always causes concern. You don’t know if it’s a problem with the engine, the brakes, or something else. But what if the problem is with your subwoofer? and How to tell if a car subwoofer is blown?

In short words, to check a blown subwoofer first, check physically for any external damage. If the subwoofer looks damaged, it is likely blown. Another way to check is by measuring the resistance with an ohmmeter; a blown subwoofer will have infinite resistance. Finally, you can also test for a blown subwoofer by playing music through it and seeing if the sound and bass quality is distorted.

This is a simple answer, but don’t worry, I’m here to help. In this article, I’ll teach you how to tell if a car subwoofer is blown in detail so that you can get it fixed before it becomes a bigger problem.

What Does “Blown Subwoofer” Mean?

A blown subwoofer is a subwoofer that has been damaged and is no longer working properly. The damage can be caused by several things, such as overloading the subwoofer with too much power, playing the subwoofer at too high of a volume, or even just physical damage from a bump or accident.

In addition, blown subwoofers can also be caused by a manufacturing defect. This is why it’s always important to buy from a reputable brand and to make sure that you have a warranty just in case something like this happens.

How To Tell If A Car Subwoofer Is Blown?

Here are the top 5 common ways to check if a car subwoofer is blown. By using one or more of these methods, you should be able to confirm whether or not your subwoofer is blown.

1. Check For Physical Damage

The first and most obvious way to tell if a car subwoofer is blown is by checking for physical damage. If the subwoofer has been damaged, such as by being hit or dropped, then it is likely that the subwoofer is blown.

You should also check the wires and connections to make sure that they are all secure and not damaged. If you see any bare wires or frayed insulation, then this is an indication that the subwoofer is blown.

To check the subwoofer physically, look for:

  • Dents or cracks in the metal casing
  • Loose or damaged wires
  • Frays or bare spots in the insulation

2. Measure The Resistance With An Ohmmeter

If you have access to an ohmmeter, then you can use this to check if the subwoofer is blown. To do this, you’ll need to disconnect the subwoofer from the power supply and then measure the resistance across the terminals.

A healthy subwoofer will have a resistance of around 4 ohms. If the resistance is infinite, then this means that the subwoofer is blown.

3. Test The Subwoofer By Playing Music

Another way to test a car subwoofer is by playing music through it and seeing if the sound quality is distorted. If the bass sounds muted or distorted, then this is an indication that the subwoofer is blown.

4. Look For Signs Of Burning

If you see any signs of burning on the subwoofer, such as blackened areas or melted plastic, then this is a sure sign that the subwoofer is blown.

5. Check The Subwoofer Cone

If you can see through the grill of the subwoofer, then you should be able to see the cone. If the cone is damaged or deformed in any way, then this is an indication that the subwoofer is blown.

These are the most common ways to check if a car subwoofer is blown. If you suspect that your subwoofer is blown, then you should take it to a professional to have it checked out and repaired.
