Bazooka bass tube problem

[all_individual]

Alright, since I couldn't quite register for the bazooka forums I thought I'd try you guys. Here's whats going on...

I recently found a bazooka bass tube that used to be my uncles, and I picked up the two harnesses (one goes to the stock unit and the other to the tube). They say "just plug and play!" but of course its never that simple. With the new harnesses connected and the tube grounded, the stereo only plays sound out of the front right speaker. When I fade or bring the balance over, the sound goes to nothing. Any ideas on whats going on here? I'm not sure how much you guys know about the bazooka bass tubes but hopefully we can get it resolved. Its for a 2004 PT.

I have the Bazooka Base Tube that imitates the NOS bottle. I had to add an amp (that's situated under the drivers seat) to run the tube. There may be other tubes that run without the amp and I don't know which one you have.
