I installed my subwoofer yesterday and I was playing well but today, when I started my car, the subwoofer began to move crazy without music so I turn off the radio and the subwoofer was still crazy...
Any idea what went wrong ? I will post a video in 3 hours about the problem so you will see by yourself.
Thanks

good idea. cause crazy doesn't tell us anything. and a thing to check is that all connection are good. the rcas. the ground wire is a definent thing you need to make sure is secure.

I checked everything. The ground was not well secured on the amp ... Thanks
