Just for documenting purposes. Looks like the stock speakers are 4 ohm, LPT 130, 40watts. Here are some other #s on the label in case its of any use: 33867 or possibly 33887..my eyes arent that good. Nokia audio electonics, 49104 30246/02 Made in germany. They look to be 5" diameter cones with a metal housing with a 4" hole center to hole center square layout (in other words, four screws). The speaker was close to 2" deep, but the space seems to be able to accommodate up to about a 3" depth minimum. and yes, I did indeed fine a split in the cone once it was taken out. The wire attachments were assymetric slide on posts so the speaker wire was easily detached. there is actually a pair of these on ebay right now for $100, but I hate Ebay and rather go aftermarket.

latest update. It seems the biggest trick here is finding a suitable replacement speaker primarily from fit. The diagonal dimension of the screw holes is 5 5/8". Verifying that the 5.25" speaker mounting holes extend this far out has been an issue and as a result, I have yet to purchase anything. I was looking to just replace the driver, but it seems most quality speakers are either component system, or 2,3 or 4way system or coax connected. As Im trying to minimize headache, I am not pursuing an coax systems. I am likely to go with a 2,3 or 4-way system if I can find a suitable 4 ohm one with correct mounting. If anyone has some suggestions here, please let me know.

If you can't find a 4-ohm speaker, then I would look for an 8-ohm one that had the right mounting hole pattern, if your goal is to not do any sheet metal work to the car or speaker.
 
An 8-ohm speaker would give you a slightly lower sound level, but should not damage anything, and you can always turn the volume up a bit to compensate - that is, unless your drive around with the volume turned up to max all the time anyway .

So to followup on the end result. Many of the 6.5" speakers I found had mounting hole configurations that were well matched to the preexisting holes in the sheet metal. I ended up just putting in a 2-way Sony XS-GTF1627. a pair for under $50 online or you coudl just go to bestbuy for a little more. These speakers are only rated at 35W which is a little light for my receiver, but it works well enough for my purposes and i didnt have to do any cutting whatsoever. i would recommend better matching though in this regard. I get overmodulated when I want to turn it up on the highway, but for the most part, they are ok sounding. The existing connectors fit directly on the slot posts of the speakers. Also, the stock grills may tend to just touch the flexible portion of the speaker cones as they have a 5" protruding ring on the inside. But whatever, its done and under an hour easily and closer to 30 minutes. A single flat head screwdrivers and a small socket wrench and socket were all thats needed and less than an hour total time.

I'm sure I would have gone the same route. Most speakers are probably a lot better than my ears anyway.

#89 of 104 Looking for a car by hambonecampana

Dec 02, 2011 (5:52 pm)

I'm looking to purchase an inexpensive, older two seater (ideally a convertible) that I can keep for years to come as a second car. I'd like it to be reliable, fun to drive, won't plummet in value, and a car that, if something breaks, there's information out there to teach me how to fix it. I'm pretty young, and I don't know a whole lot about cars (although I am pretty handy), but if I learn on the way that's great. I don't want it to start out as a project car, but if over the years it gives me some projects, I'm okay with that. I'm thinking about an older BMW Z3. According to edmunds prices a 96 would should come in at about 4-5k. Would appreciate thoughts from some that have gone before me. Thanks all!

Well I'm not so sure you really want the little 1.9L 4 cylinder engine, unless you don't mind being slapped silly by minivans at the stop light. But a '96 is affordable to buy, that is true. It would be nice if you could opt out for the first 6 cylinder model....was that 1997? Yeah, I think that's right.
 
As for fixing them, you'll have to gear up some, and get a good scan tool, a volt/ohm meter and a factory workshop manual. No reason why you couldn't do things like fluid changes, brake pads, tire rotation, belts and hoses, that sort of thing. It would be a much higher learning curve to get into engine work or electronics.
 
It would be a great idea also for to a) join the BMW club of America and b) line up an independent BMW repair shop that you can develop a relationship with. To take care of a car like this, you need a support system so that you are not dependent in any way on the dealer for service or parts.

Wow. Thanks for the quick response! I've read mixed reviews about the 4 cylinder, a couple people said that the weight balance was better so it had better handling. I do have a great mechanic that works on imports who's a family friends.. He's been doing it for years and has 4 garages in my area. I was also considering the Toyota MR2 spyder and the Honda S2000. Any other cars that you think I should take a look at? Or is there another forum that I should post this under? (It's my first time posting in the Edmunds form).
