4 Common Problems with a Subwoofer Crossover 4 Common Problems with a Subwoofer Crossover

The subwoofer crossover devices are intended to assist the sound quality of a car's woofer, but they can be very problematic, particularly where the question of this sound quality is an important issue. The crossover of a bass, for example, although it is supposed to strengthen the capacity of the processor, it is not always capable of doing so. If you have a subwoofer crossover which repeatedly gives you problems, you might need to consider ways to improve the quality of your sound without having to replace it with another subwoofer. Common problems have easy solutions, so don't worry about complicated fixes.

Crossover frequency is Too High

 You may find that you get a lot of feedback from your subwoofer, particularly while operating the higher frequencies. This is a common problem, and is caused by the fact that higher frequency signals are more audible than lower frequency signals. If you have a higher frequency, the subwoofer will intensify the audio sound, causing problems such as grinding noises, or interference. In order to prevent this problem, most users of subwoofer crossover systems recommend using a 50 hz or lower signal. Some subwoofers simply will not take a high frequency, causing severe distortion. Other subwoofers may produce better quality sound at a higher level, but it will not be consistent, and there may be other problems.

Crossover Suffers Interference

Interference is a common problem which may be related to the frequency, or to the nature of the crossover itself. Low cost subwoofer crossovers are more likely to cause problems in this respect than more costly versions, as the latter have a better ability to focus sound. You may experience more interference from your crossovers due to their proximity to other electrical devices such as Satnavs or DVD players connected to nearby ports.

Poor Sonic Integration

This is another cause of poor sound quality in your crossover. The speakers of the audio system may not exactly match the subwoofer, and this can mean that sounds don't pass consistently between the two devices. You may find that you can reduce problems with distortion and poor sound by using a short coil system, but you may also just need to purchase speakers which can handle the subwoofer, or a better audio connection system. The subwoofer can also sound as though it has poor sonic connection due to the position of the listener in relation to the speaker mounting, as some mounts can produce distortion reproduced by the subwoofer.

Loss of Power

This problem is most likely due to a failure of the wiring connection. Subwoofers are not delicate objects, but the crossover can easily become damaged through regular use. If you find that your subwoofer regularly has power failures, you may need to open the back and try and adjust any loose or faulty wiring using pliers.
