I'll start us off with my first car. The 1985 Toyota Corolla.
Pinstriping says ELITE, and by golly, that car just reeked of sophistication. Hubcaps from Canadian Tire, and rust work done by me! (You can see the rust coming out the bottom already

).
This picture was already a year after I had started the install. I replaced the insanely cheap and crappy Clarion headunit, and Pioneer whizzer cone 6x9's in the doors. This photo shows the successor Sony CDX-CA900X headunit and ULTIMATE 6x9 coaxials. Those things had a good 1" of magnet on the back, so you couldn't roll any of the windows down beyond 1/2! Also note all of the stereo wiring hanging below the dash, held up with hockey tape
Closeup picture of the 6x9's. The speaker grilles would shoot out sometimes if you slammed the door too hard. Also, I cut out the holes using gardening shears, then later I found some tin snips! I think maybe only two of the four screws ACTUALLY held it in... the rest was flapping on the door panel
Closeup pic of the headunit. Truth be told, I miss the thing! It sounded great, had ample features, and a very intuitive user interface. Only problem was, all the controls were on a dorky "module", which I had to retape to my dash every couple weeks (didn't dare drill any holes in my precious car!).
Here's my pride and joy. A JL W1 prowedge, also bought on that first boxing day that started me down the path to enlightenment. $200, and I stayed up all night to get that deal!
At first, the 4 6x9's and two 3.5's in the dash were powered by my headunit. That's right, I had my front door 6x9's and 3.5's run in parallel off of a headunit

. Later on, I added this Sony 4 channel amp, to match my year old sub amp. It was run off of speaker level inputs, until Fuzzy and I finally got out the heat gun, and melted the air ducting behind my dash so that I could fit RCAs in!
And here is the 2ch amp that ran the subs. The 4 gauge I used to feed these amps was actually used for overhead power lines, and had about 6 strands of incredibly thick copper in them. Impossible to work with, and it was so stiff it ended up cracking the power terminal on the amp! Both of these amps were installed under the seats, which in a small car meant that you got a lot of feet on them. Thus the footprints and dirt
Here's how I installed my subs... facing inwards, because otherwise the trunk rattled too much! The box was tied in with orange rope that has been used for camping in my family since the 1970's.
Note the NOS sticker, for comedy value. Also, the trunk hinges were totally broken, so it sat crooked, and didn't seal from water.
Unfortunately I lost the pictures of my second install, which was MUCH better. I completely reupholstered the doors, and installed Elite 5's up front with NO REAR FILL! The windows could roll down completely. I swapped the Sony headunit with a Pioneer SQ unit. DEX-P99R I think?
I built an angled 2cuft box for a Xenon 12D4 using nothing but a jigsaw, and even rebuilt the entire floor of the car with 1/2" MDF. Then I turned the back of my trunk into a wall, where I mounted the Ti basscube, Elite XO, and Ti900.7 powering everything!
That was a much nicer setup. I would love to get those pictures back, but they disappeared with the original PG soundoff forum. If anyone has backups, I will KISS YOU!
