I think I have finalized my front stage choices, but I'm going to build a couple boxes for the different subs I have, and see how those sound. While that process is going on, I'm going to try to model some things on WINISD. That way, I will be able to listen to what I think I need, and maybe compare that to what WIN tells me I need. I'm also still deciding whether to pull my rear seat. I believe I'm going to have to build around it, and keep it functional...
