Well, today I built a template box to see hat i cvan get away with. I made this one with the 2 2" speakers wired in series. The box workedd out well and I have found a few ways to make some more space in this hull. Persistence is key. I believe the speaker that is on it's way to me is going to just clear in the box i'm going to build for it. I havebeen using the 3 7.2v battery apcks I have to find a way to fit everything....howver I ordered 2 9.6 v packs today which are much smaller in every way over these. No doubt it is a project to get this thing in, but one way or the other it is going in. I will try to post soem pics...I didn't take any yet because I was focused on the task at hand. Thanks for the interest though.
