Subwoofers in a cruiser mopar

Anyone have an audio system in a mopar that includes a subwoofer or 5 and is a high power system.

What do you run and how did you install it to not be too intrusive in an original dash?

I have been kicking around the idea for awhile installing a high powered system in a 68 valiant. I've been driving a newer Mercedes and now I'm spoiled and I want a system that bumps in the valiant too.

I'm not talking about a weak system for some old *** guitar rock, I'm talking about a heart pacing bass bump that will make the deck lid rattle and knock the license plate off.

Anyone?
