I decided to start redoing my system over the holidays and have made some fairly good progress. I decided that I was going to forget the rear speakers and only do front components. I have everything installed so far except for the sub (still need to come up with a box for it).

The deck I am using is a Alpine CDA-7995 so it does not have an internal amplifier. I decided that I would hook the rear bose speakers up via the rear RCA's on the deck. I received sound out of them and the volume was just where I wanted it as it could only be heard if you were sitting in the back seat and could not notice them in the front.

Everything seemed to be working fine until I tried switching stations on the deck. This caused a thumping sound out of the rear speakers no matter what volume. It only occurs when the RCA's are connected (if they are disconnected but the amp turn-on wire is still connected, there is no thump). Does anyone know if there is anything I could do about this or is it normal with this setup? I don't believe the normal anti-thump circuit will do anything as the voltage on the amp turn-on wire during this remains constant.

I realize that the bose amplifiers expect a certain voltage but was hoping this setup would work as a temporary solution until I can afford another amp and rear speakers (if I even choose to do this as I would probably never have them on unless someone is in my rear seat).

Thank you!
