If you are an audiophile, you know the importance of having a good subwoofer. It can make or break the sound quality of your car stereo system. However, like any other electronic device, subwoofers are prone to damage and wear and tear. One of the most common issues people face with subwoofers is a blown fuse.
A blown subwoofer fuse can affect the sound quality of your subwoofer, or it may not work at all. If you are experiencing any issues with your subwoofer, it is essential to diagnose the problem. In this article, we will discuss how to tell if a subwoofer fuse is blown or not.
First, you need to check the cone of the subwoofer. Push down on the cone with both fingers, one on each side, and notice if you hear any scratching noises or if it won’t move. If the subwoofer won’t move at all or makes any unusual noises, then it is likely that the subwoofer is blown.
Next, check the suspension of the subwoofer. When you push in, is it a little more difficult to push in or is it real easy, and does it flop back and forth? If it does, that indicates that the spider is wearing out. Of course, if it is a brand new subwoofer, it will be tight and won’t have any issues.
Finally, you need to check the terminals. A subwoofer has a positive and a negative terminal, and to check if it is blown, you need to use a digital voltmeter. Hook up your positive lead on the positive and your negative lead on the negative. This sub is rated at 4 ohms. You want to make sure that there’s nothing touching the cone and that you’re not in an environment where there’s air that can make the cone move.
If the reading stabilizes or deviates only slightly from 4 ohms, then it is okay. However, if the reading jumps all over the place, you need to be concerned. If it deviates significantly, such as reading 2 ohms all of a sudden, then it is more likely that the subwoofer is blown.
In conclusion, if you are experiencing issues with your subwoofer, it is essential to diagnose the problem. By following the above steps, you can tell if a subwoofer fuse is blown or not. If you find that the subwoofer is blown, you may need to replace the fuse or get a new subwoofer.
