Is this the first time you fabricated a custom enclosure or even a regular enclosure? but anyways...yea it's getting there. See with my enclosures, I like showing off the amp. Well that is it if looks nice. But I'd somehow move your amp that's laying on the side, and bring it up to the top of the enclosure. Hide a neon light when the amp is and cover it with plexi. It'll look really nice with the plexi and neon lighting up the amp. I'd used carpet rather than vinyl because it blends in more with the trunk. You're trunk is carpet. Why not match it? G' Luck!
