I have recently purchased a 1990 civic ex, I installed the system from my old car into my civic, This car is by far the worst ive ever seen, anything that makes noise electrically, I can here.. it has the alt whine when running, pretty loud as well, but when i shut the car off, i can here the door beeper, and if i roll up a window, or anything electrical, like the mirrors, i can hear it though the speakers... has anybody else ever had noise problems this bad in their civic?
