Tube amp for my car

[lnx64]

This is going to be an odd request.. But I love the sound of tubes.. Even the headphone amp on my Mac is tube powered, and in the livingroom when watching movies and stuff on the Apple TV, we use an amp that is tube powered.. Love it, LOVE it. Especially when people think tubes aren't that good, and they hear a gun shot or explosions in some action movie with regular 8 ohms speakers, and they are like "wow, and there's no subwoofer?!"

Now I want it for my car. Someone I work with, has a Fisher 500c receiver, that is pretty banged up. Electrically it works and had the caps replaced, but it has no casing, and is just a bare chassis.. I was thinking, if I replaced the speakers in my car with a higher impedance other than 4 ohms, perhaps 6 or 8 ohms, I could use this amp, and even use an inverter to provide it the AC power it needs.

Now, that should be easy to do. My car is already wired up for an amp, which has bit the dust, and it needs to be replaced, so this is why I am thinking of doing this.

Can that wonderful old amp be retrofitted into a car? It would be mounted in the trunk of the car, but on my Caprice, the trunk actually doesn't get hot at all, even in hot weather, it's rather nice in there, so heat won't be as much of a concern.. Though I would install fans anyway just to play it safe.

Is it a crazy idea, or an interesting idea? Should I do it, or is there a better solution for tube sound in the car?

My commute to work is an hour, so good tunes is very important for me.
