That amp and those speakers will work great. I mentioned in a thread earlier today the space right between the deck speakers (underside) is a easy place to mount an amp and keep it out of the way (and out of site). Not saying it's the most convenient spot for adjustments but once they're setup most people rarely touch them again anyway.
Yeah, that was where I planned on mounting the amp as long as I have enough room between the speakers. And those speakers will actually work better as low pass speakers for bass being they are only 2 way, correct? Since I won't really be shooting for higher range frequencies like a 3-way handles?
