I haven't done any of my installs yet so no pics but I have always been a fan of hiding or disguising stereo equipment. With a wagon that's tough but it's impossible with a hatchback.
On my 80 hatch the amps will go under the front seats, a pair of 3" highs will get mounted in the stock dash speaker hole & some 6" mids will go behind the stock door speaker grilles. There's a set of holes & grilles at the rear that take a 4 or 4 1/2" speaker so I'll use that location as well. I don't want to hack up the nearly pristine interior of this car for speakers so I'm using every available stock hole I can find.
I didn't want a big sub box & I want to keep the spare tire so I dug up these 8" Bazooka subs. A blue one for the 80, 2 white ones for my wagon & a purple one for my half hatch. I've used tubes before & they offer great sound for the money.
