I have the kenwood KVT-911DVD head unit and the Infinity basslink. Today I had to disconnect the negative battery cable to move the alternator (damn spark plugs)

Anyway, when I connected to cable back, the basslink will only come on when I have it on the AM/FM tuner. It will not kick on when anything else is selected (i.e. DVD or SIRIUS).

I didn't touch any thing having to do with the stereo, so what could have happened?

Please Help. I am out of ideas.

Thanks

Joe
