question plz help

my system was working fine but one day when i turned my car on i noticed that when i have my stereo off every time i push my lock button or anything electronical my subs hit what is the problem and what do i need to do i am new to car audio.

Sounds like one of the lock wires is pulsing signal into the rcas, like there to cloase and your hearing the feedback from it.

Def. some electrical interference somewhere, you might check your ground, many times that's where it comes from.
