floor speakers for 107
I know there have been several different questions on how to upgrade the speakers in the 107 because I've looked at them. Therefore I thought I would have a go at putting speakers on the back floor. I replaced the Becker stereo with a Blahplunkt Monte Carlo MP34. That in itself is really a treat. I was amazed that by converting audio files to MP3 format, I could put over 15 CDs on a single disc. I bought a couple of Panasonic 6+1/2 inch speakers (model CJ-DD163) which are very shallow. Next I took a piece of 2 by 8 and cut it into a square. Since the 2 by 8 really measures 1+1/2 by 7+1/2 the overall square is 7+1/2 each side. After planing and sanding, mine is a tad bit smaller. I cut two of these for each speaker so that by stacking them, it is only 3 inches high. From a block of wood I cut out the center for the speaker as if I was going to top mount it. Then I took the speaker cover, laid it on top, marked it, then routed the wood down about another inch. This gets very close to the edge of the wood, less than a quarter inch, so be careful. Once the speaker drops down, it is screwed into the 1/2" shelf left by routing the wood but now instead of being top mounted, it is recessed. The grill normally protrudes 7/8ths inch above speaker but it now is about an 1/8 inch below the surface. The bottom piece of wood is cut circular as big as possible. Now mount top to bottom and you get a recessed speaker of only 3 inch height. I covered mine with fabric to match the interior. They slide under the seats from behind. You do have to raise the seats first and you lose about an inch of height (I'm 6"4") but with the top down it's not a big issue. The seats dip in the back in the center, so place the speaker as far to the outside as you can, that way the center dip will rest on the wood and not on the grill. Since they are not permanently mounted in the car, they can also be placed upright on the floor or on the back shelf without a problem. The floor seems to sound better, plus you get the bass vibes right up through the seat. The front speackers I replaced with Sony XS-W4021 four inch speakers (slid right in) and a bass blocker to keep them from vibrating. It's inexpensive and works great for me.

Looks nice, but I would rather keep the seat movements operational. I have retained the two speaker holes in the carpet covered plywood jump seat floor behind both seats since recarpeting, and have bought new speakers to replace old! Haven't tried them yet, but I do antisipate adding sound dampening insulation if needed! BB

I also have this installed in my '86. I heartily recommend the optional wheel-mounted remote control. I got it for $40 with a battery, it installs easily and in a completely reversible manner, and I don't see how I lived without it.
I searched for a stereo for a long time before settling on this model. I liked it because it doesn't look like there is a rave going in your car when it's on!

Still I wish I could mute down the display brightness. At least the Monte Carlo doesn't look like a circus act when it is on like some of the units I looked at.

BusyBenz, the seats are operational, they just do not go to maximum seat drop. They still slide back all the way. I only have to slide the seat forward to move the speakers to the back shelf if I really feel crunched for space. Also what's nice is that they are fairly well hidden on the floor so that I don't worry too much about leaving the car parked with the top down.
