Engineering Some Thump

Suppose it might fit under here?

This week I'm beginning the search for stereo components for the old truck. My plan--though it's only in pencil at the moment--is to take a weekend in October to tear the entire interior out and build the perfect beast.

This will not be a standard stereo installation. I've got some significant obstacles to clear. In most pick-up truck installations, amps and subwoofers can be built into wedges behind the seat. The 1970 F100s, however, carry the gas tank there. (Yep, that's a little scary.) My first decision, then, is whether or not to relocate the fuel tank to the rear underside of the truck. That's much more costly and involved than you might think. If I were doing a restoration or resto-modification to this truck, then I would likely go for it. But since my aim for the time being is a daily-driver and not spending too much money, I've decided to leave the petrol as close to my behind as possible. Yes, my friends, this is a whole new reason why you don't want to smoke in my truck!

Without moving the gas tank, I've no space behind my seat. So, where to locate a 12" subwoofer and 1600 watt amplifier?

Then there are the speakers to consider. Where to mount a couple of 3-way speakers since the door panels have window mechanisms behind them and kick-panels are utilized for vents?

Finally, there is that dash speaker opening that houses (still) a crusty and dusty Ford factory cone--I can't wait to get that thing on the bench and see what it looks like. What kind of creative use can I make of that hole? A tweeter? Narly! (In my best Spiccoli voice.)

So I'm crawling around the cab with a tape-measure and crawling the internet looking for components that might work with the limitations I'm facing. I'll keep you posted.
