My Sub-Woofer has Stopped Working

The first thing to check is that your amplifier is not in protection. If it is, this could be a sign that there is a problem with your sub-woofer or amplifier. The easiest way to check if your sub-woofer is causing your amplifier to go into protection is to disconnect the sub-woofer and power up the amplifier. If it does not go into protection with it disconnected, your sub-woofer is the problem. Check for a burnt smell, then try and move the cone gently by pressing down in the center to see if it has seized or is rubbing. It should move freely if the coil is not damaged. If the amplifier still goes into protection when you disconnect the sub-woofer, there is every reason to suspect your amplifier may have an internal fault. Unfortunately this does not mean your sub-woofer is guaranteed to be fault free as the amplifier may have suffered as a result of the sub-woofer failing or vice versa so at this point we would recommend that you return either one or both of the units to your place of purchase for inspection by the authorized dealer under the warranty provision of the product (if applicable).
