Sometimes after installing a new sound system, you may experience some bothersome engine/alternator noise, typically characterized by a whine that increases in pitch with engine speed. Though this is usually caused by a poor connection to the ground, sometimes this problem occurs anyway.

After checking all of your grounds and you still are experiencing engine/alternator "whine", our quality Radio Noise Suppressor might be just the thing to eliminate this very annoying problem.
