The correct size for the door speakers is 130 mm. 5 1/4 inch equals 133.35 mm - thats why they sometimes (depending on brand) doesn't fit without enlarging the hole in the door. | ||

I need fix the door panel itself a bit and tried to remove it. Is there a trick to removing the door lock knob? I stopped trying to simply unscrew it when it felt like something would break sooner than it would come loose. | ||

Alberto, Yes, many of the 5 1/4 speakers are considered "oversized" and don't fit in the stock locations. I've found this in the past. Thanks for the MBQ part number- this helps that you have had success with the speakers- even though they don't sound terribly good. They probably sound much better than the stock speakers! Thanks again for the part number- it really helps. Jim | ||

James: I ended up using MB Quart DKD113, which are 5 1/4" coaxial speakers and I kept the in dash tweeters that came with the car intact. I got them for $99 (I saw that price on the internet and at Al & Ed's, a local shop down the street from me matched the price). I do not like the way they sound that much, I have to put the Bass at maximum to get any punch from them (they sounded great at the store, but they are in a much bigger box there, which accentuates the lows). The good news is they install right in, with the DIN adapter that comes with them (the fastener pattern was different for my car between the original Ferrari speakers and the MB Quart, I was able to use two of the existing holes and drilled two new ones; not a big event.) The sound thing does not worry me that much since I have an older head unit that is not the most powerful of units plus, I rarely turn on the radio anyway, prefering to hear the engine while I drive. Not all 51/4" speakers fit, I tried putting in the afermarket 5 1/4" speakers that are in my Miata in the Ferrari and they did not fit. Measure the cut out (which is about 4 3/4", if memory serves), and make sure your speaker cut out requirement is no more than that. Depth does not seem to be limitation. | ||

Mark, Yes, I've looked into this area. There is actually quite a bit of room in there. But, I was unable to find an amplifier that would fit. In the late 80's and early 90's, there were a number of amplifiers produced that were smaller. Today, everything is big and flashy. I'm now going the other way with the car, trying to make it as stock a possible. Also, many of the new in-dash radios have a great deal more "punch" than the older versions did. Funny that I was never able to get enough sound out of my system to be comfortable over the engine noise(music?)- so I decided that it wasn't worth the headache- literally! So, I'm interested in finding out what model MB Quartz speaker will fit into the stock locations, and I'm in search of a "high-power" deck. That should be just fine as the radio is used primarily to keep me entertained during washing and waxing! Thanks. Jim C. | ||

James: In my 328, my amplifier is under a panel,in front of where the passenger's feet go. | ||

Frank: Where is the crossover located? How did you remove the tweeters on the dash? Where did you buy your speakers (never heard of the brand)? Thanks. | ||

Frank, Would you be willing to post a digital photo of your tweaters? How about the model number of your choice for MBQ speakers? Everyone, I finally removed my amplifier from the spare wheel area, as the heat is a problem and it looks bad in that location. Does anyone have any cool locations that you may have hidden your amplifiers? | ||

I put MBQuart speakers in doors and MBQuart tweeters in the dash of my 1986 328 GTS that fit perfect and still looked stock. I did add a better crossover though. It sounded great. | ||

David, I reread my response and I realize it was not complete enough to answer your question. Yes, the door speakers are receiving the full range sound. The tweeters are connected thru a high pass filter (the capacitor) across the door speaker. I put full range speakers in my doors and left the tweeters connected to bring the highs up to more ear level. | ||

Mark: The door panels are not too hard to work with. On my '87 there are approx (3) screws in the carpet by the speaker, one in the back, then you have to take the (2) door opening handle screws out, and there are several screws holding the pull handle. You have to unhook the switches (may want to mark them so you get them back correctly and unhook the door opening cable (when you put it back on it seems to go on easier when all the switches are hooked-up) . The job is not too bad-more complicated then an American car, but not too bad. | ||

I don't remembe any shophisicated cross over when I took the orginal speakers out of my 86 mondial. it has the same set up with the tweeters in the dash and low end in the door. I replaced them with need MB quart with a new cross over. The roginal speakers say ferrari on them - no sure who made them for Ferrari though | ||

My question is, are the door speakers actually receiving a full range signal, or only the lower frequencies?? Does anyone know? In a "seperates" situation, the signal is split, so the highs go to the tweeters, mid-lows to the door speakers. So installing full range door speakers may make little difference. | ||

I think I am going to go with a full range, as I am not sure of the condition of the tweeters in the dash. From feeling the carpet on the outside of the speakers, I think the door speakers are round. I know that there are some decent 2-way round door speakers available. Thanks for your help and advice! | ||

If I remember correctly, the schematic shows that the tweeters in the dash(stock) are connected to the regular speaker line thru a capacitor (called a cheap crossover). | ||

I guess my question is: Is it worth it to replace the speakers in the doors with a "full range" model? Or do the door speakers have the highs rolled off by the crossover? Or is there a crossover at all? Perhaps the door speakers ARE full range and the tweeters just have "blockers" to prevent low frequencies from getting to them...? | ||

I was interested in upgrading the speakers in my 87 328 as well. It has tweeters in the dash and a speaker in the door. Is this stock??? The sound is only fair. Alpine cd, Alpine amp and not sure what brand speakers. What size fits in the doors? I am imagining this is a true seperates system, that being there is a crossover between the tweeters in the dash and the mid-woofers in the doors.... | ||

I put new speakers in mine without removing the door panels. I did have to take the screws out from around the edge and loosen the inside handle. This gave me enough room to allow access to the lower front area where the speakers are. P.S. New speakers, new radio... sounds great, but I've only had it on three times in the last two years. The real music comes from the rear  | ||

I am going to replace the speakers in the doors as I think they are the orginals and they sound pretty bad. It looks like I need to remove the panels to access them. I have never removed the panels before. Are there any issues I should be concerned with? If anyone can give me some help I would appreciate it. Thanks! |
