That's completely contra indicated. Actually finishing a DIY amp into a case is forbidden....
I remember my first mobile disco that I built from kits in 1980.
Did my first gig with the amplifier on a piece of chipboard !
At least it stayed cool.
Tripped over speaker wire and it yanked out blowing fuse.
Easy to change output fuse and continue.
Before I worked at Motorola I ran the service department at an Olson Electronics store that just happened to be at the end of Frat House row at the University of Miami.
Olson's sold some house branded 15 inch woofers that were made by Eminence, and capable of eating full power output of any of my DIY amps at the time, and certainly everything the average college kid could buy....even with a car load of daddy's money.
My brother and I stuck one of those speakers in an unscientifically designed cabinet of about 4 cubic feet. These made for some serious bass, but not much else. They were just right for the dance floor.
John Ravolta had not yet heard of the Saturday Night Fever, and the Bee Gees were still making good mellow rock, but this was Miami, and the Latin beat was already booming. We sold those boom boxes as fast as we could make them.
We also made some small boxes with a 6 X 9 inch car stereo speaker in it for fill-ins where people might actually want to hear the music. I found a pair of them in my warehouse when I was cleaning it out before moving out of Florida. That blue surround lived for about 2 minutes of torture before I tossed them in the trash......remember, I made these in about 1972 or 73. Times have changed just a little.
Disco came and went, so did Motorola (and IBM) in south Florida, but the Mirage disco lounge that was built right across the street from the Motorola plant in the late 70's is still there and still thumping out the Latin beat. It don't need to be HiFi, just boomin loud.

Olson's was an interesting business; I worked there for a spell doing floor sales in my later college years. Seemed to be the "grocery outlet - bargain market" of the electronics stores; you never knew what was going to show up (on top of their line card items from Fisher and Sanyo). I wonder who the buyers were, how they decided what to get - and from where? I recall the "regional manager" (bosses boss) had a nice home with a pool and a 57 chevy in the garage...
I remember opening up a shipment of Sure phono cartridges - all different models. I'd mount them in headshells to try out in the store - some of them sounded pretty good.
I also remember that 6X9 with the distinctive blue surround...

That was a Jensen feature back in the day. I had a pair of their base model 6 x 9s (whizzer cones) in a '72 Toyota Corolla - what a fun little car. Eventually upgraded to the ubiquitous Jensen Coaxials, while some of my more well-employed buddies reached the pinnacle - the prestigious Jensen Triaxial! The Pontiac Trans-Am of car stereo speakers.
The Olsen's store that I worked in was the #1 store in the US in sales revenue. This was due to it's close proximity to a very expensive private college. We were next door to their ticket sales office (UM Hurricanes) and a short walk to anywhere on campus. The discount outlets started appearing nearby about the time that I left, which took their toll. Sometime in the early 70's Olson's was bought by Teledyne, who also bought AR, so we had the entire AR line of speakers, their receiver, and turntable. Sales of $1K systems in 1972 in that store were not uncommon.
Those are, or were Jensen Triaxials. I don't remember exactly where they came from because I built 4 of these cabinets with coaxial speakers in them. Two were stolen out of my car in the Motorola parking lot. These two were my test speakers for quite some time, but I blew them up at least twice that I can remember. Both dead speaker events were during my solid state amp building days in the late 70's and early 80's. Working at Motorola had many perks, free silicon was one of them Their sample form even had a check box for "home project."
I now have a less "disco" looking set of test speakers that have survived everything that I have thrown at them for about 10 years. They can be seen here:

I hate doing the second channel when first channel of an amp is done. Now I have undone one from september.
I hate this too. Used to find item by sound location (path difference between the lugs) but since one ear dropped HF response, I now find myself "Looking for love in all the wrong places".
So..... did you find it after 20 minutes, or just give up?
(continues crawling on the floor)
Glad I'm not the only one, I wonder how many hours delay it has caused me in total
