hello sers,

I have a question regarding this irritation sound (i think the sound comes from the speakers) yung parang sumisipol ng matining. I don't know how to describe it. I usually hear it sa mga lumang taxi hehehe... sa speakers din lumalabas. Ano kaya ang problema nun? I'm assuming that something is wrong with my wirings? Baka may ground na mali or something (I'm just guessing here).

If you have the same problem please let me know how to fix it. Thanks for your help in advance.

By the way, the car is honda hatchback eg.
