A question on our Youtube channel this week inspired a little post to help you with audio troubleshooting subwoofers. Â No sound? Â No idea why? Â Here are 5.1 (naturally) tests you can try at home to see what the culprit may be.
- Â Is it the coaxial cable itself?Â Test this by connecting your subwoofer in what’s called the Â ‘high level’ way:Â use speaker wire to make the connection. If it makes sound, then itâ€™s the coaxial cable that is at fault and you need to replace the cable.
- Have you been rocking? Â Another common problem with subwoofer sound or lackÂ thereofÂ is thatÂ just from playing aggressively, or being knocked, or an earthquake, the lead could come off on the driver â€“ either the positive or negative lead. Â To test for this, pull the driver out of the subwoofer to double-check that the positive and negative lead are still connected. Â If they are, continue your search. Â If one has come off, carefully reconnect it and test your subwoofer again.
- Am I on? Â Test 123, test 123 . . .Â Unplug the coaxial cable from the receiver, but leave the other end so itâ€™s still hooked up on the sub. Â Take the coaxial cable end that you just removed from the receiver and then tap it gently.Â If you get a thumping noise then you know the sub is working and the problem is the receiver. Â Which leads us to . . .
- A little weather in your area? Â Most commonly, if there is a power outage, receivers will go back to the manufacturerâ€™s default settings, so you have to go back to the setup menu and reactivate the sub within the receiver.
- Straight from the source: You can take a source out of anything â€“ such as a dvd player or cassette deck â€“ that has a constant source, and plug it directly into your subwoofer.Â If you can hear thumping, you know it is working and your audio troubleshooting subwoofer test needs to continue. Â Thankfully, the last tip is a simple one:
.1 If there is no LED glow present, check your fuses!
