im getting a high pitch winding sound from my rear speakers connected to the amp sometimes.. whats causing this?
i got the same thing, when its loud enough i cant hear it. lol. thats my current fix. try cleaning your earth point? i also have rear speakers amped. lets know if you find a solution.
Yeah i suspect its my connections, i disconnected the rear speakers and go better bass and sound as i did it with the amp still connected.. I'm going to play with the gain settings on the amp to, i think its set to subwoofer
if the sound is only evident when the vehicle is running, usually its engine noise. common fixes are better earth cable for battery, better route for the power cables, separate the rcas and power leads for amps as much as possible, install noise suppressors "ground loop isolator" on the speaker rca's at the front or the rear of the run, improve amp earth points by sanding the mounting area back for a clean contact. use higher grade cables etc.
Google "ground loop". PS. Eliminating the ground loop will give you much better sound than "filtering" it.
