: Amp Feed back problem

I installed two 12in Alpine subs. I wired the amp +/- directly to the battery and the remote turn on to fuse #12. I ran leads off the factory sub to the high level inputs on the amp. Now my problem is this. When the system is on it sounds fantastic. If I turn the radio off, within a few seconds I get this god awful continuous rumble from the subs. It stops immediately when I turn the radio back on.

What can be causing this?

Thanks

You are most likely getting noise over your 12v line, I had to add a noise suppressor to kill the feedback coming in over my speakers/subs. You can google them (they are relatively cheap and effective)
