Audio System ideas

[1953chevyroc]

I know, I know, "the sound of the engine is all you should need."
But I like listening to music while on the road. So I'm curious about what you guys have done or what you would do.
I'm going to use a Glide Engineering seat, so I will put the head unit under it and run a usb cable up through the seat for easy access and a clean look. The speakers will be 6 1/2" coaxials (probably Hertz units) in the doors powered by an appropriate amp. And a 10" JL TW3 sub behind the seat to round it all out powered by a JX500/1D.
Thoughts or suggestions? Or better yet, pics of what you have done would be fantastic.
Thanks guys
