Sorry, I promise I'm not a subliminal EMSpowered saleman. *buy EMSpowered*
Just joking. I've just always heard the service there tends to be pretty good.
And I've helped build quite a few boxes, so I can completely understand needing something built to personal specifications.
And I don't ever use my storage boxes either. I'll be cutting them out, but for different purposes...I'm going to strip out my MR2 and do as much weight reduction as possible. When I get a second car I'll put a sound system in that though.
