Keep out unwanted noise that interferes with your car’s stereo system by attaching an audio noise filter that blocks alternators, batteries and other sources. High-quality audio is all about separating the clear signal from the garbled noise. However, in a vehicle, there’s a lot of noise to sift through. Your car’s engine and electronics put out many frequencies that can interfere with a radio, MP3 player, amplifier or speaker — and the result is often a humming, buzzing mess. Alternator whine is common source of unwanted speaker sounds. Noise is also picked up by ground wires, patch cables, antenna leads and other components that can’t be properly positioned.
Many customers ask us how to get rid of engine noise in a car stereo system. A car audio noise filter is an easy way to block this interference so you can enjoy clear audio no matter what you’re listening to. Radio noise filters are designed to specifically block the frequency ranges causing sound distortion. OnlineCarStereo.com has vehicle noise filters from Orion, Axxess, Metra Electronics and other leading brands that ensure your music’s signal is the only one getting through.
It’s easy to put up a wall that won’t let engine noise enter. Just plug your audio noise filter between the device and the 3.5-mm or RCA jack as appropriate and you’ll be all set. There are two primary types of noise filters depending on your needs. A ground loop isolator works exactly like it sounds, using a transformer to isolate the ground path so a voltage difference between devices won’t create a hum. An electrical noise suppressor, on the other hand, filters out every signal that falls above or below a preset frequency band. This option will prevent alternators, starters and other electrical sources from butting in the way of your tunes.
Users also have two ways to install a noise filter for their car audio. An alternator noise filter goes between the alternator and the battery to block frequencies at the source. The other option is an inline noise filter that’s placed in the head unit’s power cable. Talk to our experts if you need help choosing the right filter.
