hey guys, this project is becoming more of a promlem then enjoyment.

I installed my head unit, Alpine 7874, anyways, the thinkg wouldnt work with the sub, I did what morning said, got a relay, then wired it up to the remote wire going to the sub. It worked beautifully, for about a week.

Now this mornin when I turn the stereo on, it started to go on and off really fast, and I couldnt turn it off, all I hear is the relay going on and off, when I ungrounded the relay the stereo worked fine (without sub).

I used my friend relay too same thing happened. What happened all of a sudden?
