Default DD D4.90 Install Questions

1.) What channels and polarities bridge the amp? It's not in the owners manual.

2.) Can I use only 2 RCA inputs? I see a 2/4 channel button.

OK so I have everything looking good except for one small problem, my fairing won't go on. It looks like the amp isn't low enough in the tray. Do I need to whack the mounting feet off or something?

I am using the J&M tray in my Rushmore, but to get it to fit on the stocker i lost the mounting tabs and cut a little of the tray to get the amp to sit lower. I'll find the pics and post em

I ended up putting some spacers under the back and that rocked it down enough to get the fairing on. Thanks for all the advice. I will be making a thread soon to cover my install experience and review the setup.
