Odd question this one.. my parents in Hong Kong have a Vspec '92 MX-5 ( the cars there are Europe/Asian hybrids) one thing that it does retain from the asian design is the double din radio, which unfortunatley is knackered!! Since they do not wish to have to pay mazda to replace the system, they asked that I might buy a UK stereo and bring it over to be fitted when I am next there. The trouble is that as you all know the UK ones are single din. Firstly how hard is it to convert and what is required? Also, the radio is not an issue as they only want the CD function so are there likely to be any other compatability issues?? Thanks for any views on Euno conversions to UK systems. (12/99)
Surely it would be much cheaper for them to buy a double DIN system (not from Mazda) in Hong Kong than to buy a set over here. (12/99)
Longmill sell a double din radio in the UK for a couple of hundred quid. (12/99)
If you want to fit a single-din radio in a double-din slot you just need the mazda 1-din coin tray - it's about 15-25 quid from your Mazda dealer. (12/99)
Rather than buy a brand new one why don't you buy a second hand Japanese one that someone is replacing with a UK one. I can't believe that all imported Eunos's retain the Jap Radio and simply use band expanders. It should be cheaper than getting a double din in the UK, in fact I think I know someone with a double din rad/cass/cd from a Toyota Celica....... FM Radio uses Japanese frequencies though. (12/99)

My Roadster had a 1.5 (-ish?) din stereo when I imported it, plus a (half-din I suppose) small coin tray thing below it to fill up the rest of the double-din gap.

I replaced this combination with a 'standard' european single-din Alpine unit, plus a din-sized coin tray/pocket thing below it. I got the latter from my local (not-so-Roadtser-friendly) Mazda owner for about 25-30 quid.

However, double-din stereos *are* available over here. In fact, I saw a Sony one in Halfords this very afternoon. (I think the Toyota Avensis has a double-din Sony unit fitted also. At least some spec models do...) I imagine other stereo manufacturers do them as well. Better to go to a local car hi-fi specialist rather than Halfords to see these.

Having said all that, surely there's loads of choice of car stereos in Hong Kong, and surely they're cheaper there as well..? Oh, and do the wavebands span the same frequencies as in the UK? (i.e. Over here FM is 87.5-108MHz I think.) (12/99)

The best double-DIN stereos come from the US. Take a look at http://www.alpine1.com for Alpine's range in the US. I'd love one - but the radio just won't work properly here. It uses huge gaps between the frequencies, and so misses out half the stations here. I'd buy one if there was a converter around to do the job of shifting things around so you could bodge the radio tuning (I only listen to one station anyway!), but there isn't. And no, the Jap radio expanders won't work. (12/99)
Why not just put a decent head unit in along with a din-size equalizer? That would fill the hole (12/99)
I know HK Tellys work fine; parents liked there for a while years ago. Probably the radio is "UK-spec" as well. (12/99)

A young lady wants to replace the radio in her Roadster. Her car radio man tells her she needs a deeper 'cubby hole' and something to fill in the hole left in the dash when the original radio is replaced with a 1 DIN unit. I know someone somewhere once posted the pukka Mazda part number for the cubby hole (her local dealership is being about as helpful as you can be without actually telling someone to p**s off). Any thoughts / suggestions from someone who's replaced their Panasonic radios ?

I still have my original one (It's not terrific, but I figure a 1.5 DIN unit with a matching CD player that makes it look like a built in 2 DIN unit isn't too attractive to spotty radio thieves......touch wood) (12/99)

My double DIN radio has annoyed me once 2 often by either not playing CD's/not turning on, so i'm planning too get a new radio for xmas. Sooooo I was wondering how everyone covered the spare 1 din slot left after changing. Can you get little cubby holes or just blanking plates. A really deep one, with possibly some sort of cover would be really cool. (12/99)

You do not actually need a cubby hole .. get some black foam board from a sign maker .. plus 4 off 7gx1/2" or similar chipboard screws with the end filed off. Mount the radio in the top slot using the old radio side mounting rails then fit the foam board under the radio to the removable centre console; there are screw holes hidden behind it. This is the way I have added electric windows and two gauges (carpet between seats) .. it does take a bit of time but just a blanking panel is easy. I also fitted the radio so it's face is flush with the dash rather than sticking out .. as UK cars do .. looks silly IMHO compared to the flush original fitment (another UK importers bodge .. did they do anything right?)

Connectors
The Mazda to ISO stereo connector available from Maplins is Part No: MZ71, and is supposed to fit all models from 89. Certainly fits '92. The cost is about 10.00 including the VAT. The connector I have has two connector blocks which fit the car's wiring harness and a single ISO block for the stereo. The telephone number for Maplin is (01702) 554000. Halfords do one too Mazda Crutchfield sells a single-din factory look installation kit and plug to fit std wiring for around 17GBP

Filler panels
(Info from www//.miata.net/garage/audio.html except 1/ which is UK info)
1/ Coin/tray type filler = Australian conversion
The invoice shows part number HE2155235 00 but the part itself has p/no HE2190235 moulded into the back. By the way, price was 26.73+VAT. They had to order it but it only took two days. ..... 1 1/2 DIN oddment tray, which fits underneath. it's correct name is an 'ornament tuner'
2/ 0000-81-0147-1 is reputedly a single (one) DIN euro spec panel
3/ B092-55-235B is reputedly a 0.5 DIN x 2" deep panel from a Mazda 323
4/ LA03-55-235A = 0.5 DIN filler
5/ FC02-55-235A = 1.5 DIN filler, can be cut down to a 1 DIN filler, used on '90 Miatas only

Options
1/ Single DIN UK radio with filler panel
2/ Double DIN UK radio
3/ Eunos/Japan radio with dongle with or without factory CD
4/ Miata/US radio full FM and anti-theft number code with or without factory CD

Speed of Sound
Available from Performance Buyer's Club (PBC) in US. Ties into factory 1.5 DIN radios to vary volume relative to speed and has three modes, roof up, roof down, off.

Frequency convertors
Most Eunos cars with factory stereo have the dongle option fitted by the importer and the FM frequencies do not cover the full UK range, nor do they reflect the correct frequency on the display. There are two ranges available giving Radio 2 to 4 OR Radio 4 to Classic FM. New versions have a manual switch which toggles between the two ranges. Old version can be fitted by the battery in the boot in 10 minutes, newer dual range ones depend how accessible you want the switch to be.

Double DIN radio/cassette/CDs (taking up the whole radio hole);
Sony WX-C570R 499GBP list but 430 odd at top contact, I have physically tried the surrounding panel on this radio and there would be a 3 mm gap or so to fill but black rubber cable would do this easily. Fitted to Toyota Avensis in non RDS form.

Mk 2 Speakers
The Mk2 has bigger speaker holes (8") MB Quart Qm200.03 combination fits (8" speaker hole) with some grinding MB Quart 218.30's, 6.5 inch component speakers with seperate tweeter and crossover box. "I've put these in my MkII 1.8iS. The 6.5 inch drivers will fit in the MX-5 door on a MkII with the aid of an adapter ring ( I made my mine by cutting out rings from a sheet of 6mm plywood), or they might just fit straight in the hole of a MkI door I believe. On a MkII the tweeter mount is already in place on a MkI, you may require a site to site" Mark Salter

Mk 1 Speakers
Mk1 has following dimensions; (door trim off a '94 1.8 Eunos; this cars has a bottom main speaker and a tweeter in the door trim top as standard but should be representative of a UK 1.8iS (I think?));

Bottom main speaker;
Hole in steel work of the door = 140 mm
Maximum diameter flat around this hole = 162 mm
Maximum depth allowed until you hit door skin = 131 mm (no windows to foul in these cars)
Maximum height from the flat = 15 mm (= speaker surround - my fitted JBL GTO603 was 18 mm in this dimension and while causing a slight bump was not real problem - the door trim still fitted)
Maximum hole in hard-board trim of door = 106 mm
Maximum hole in fancy door surround = 131 mm (as 1.8iS in aluminium)
Electrical interface could be made with two standard 4mm wide flat terminals with no wiring cutting.

Door trim top tweeter;
External visible diameter = 60 mm
Minimum visible height = 12 approximately
Hole in door trim to mount = 48 x 48 square hole
Rated for 25W at 4 Ohms

My comment on the main speakers would be that the standard door trims are very robust but have 40% steel coverage with a small 4" hole in the hardboard. I removed the Mazda grilles and sandwiched the metal grills of my JBL's between my aluminium speaker surround and the door to allow more air movement (more mesh; less like punched steel plate) and increase the hole to the 131mm of the surround to allow more area. The current design seems to restrict air movement so that any more than a 100 mm moving cone is wasted - and in fact will just start trying to move the door trim panels and so contributes to the whole thing rattling and not producing a clear noise

JBL GTO603 3 way speakers (55 GBP) - will fit doors with a bit of a grind to the outer speaker rim to clear the securing screws (reuse originals to hold adapter ring)
Pioneer TS-E1790 17cm, 3-way and 180 watts - you'll need to drill one hole in the rim of each speaker and use other holes available.
Pioneer TS-E2090. This speaker is a 3-way speaker with a 20 cm (8") diaphragm, the pair of 2090 is effectively a pair of 8" subs. 17cm for doors;

CD holder for Mk2
Holds 4 cds in a single DIN slot; http://www.seriousauto.com/cdcaddy.html (12/99)

Black foam board? What's that? (Any pics?) Sounds like it would be easier to work on than ABS (plastic) ...but maybe not as "OEM" looking? (12/99)
Foam Board - or modeling board /plastiboard from Model shops around about £2 for a small sheet in moderate thickness. May even get it at art/craft shop. (12/99)
I believe the spare slot left after installing (a single DIN unit) is going to be taller than 1 DIN.There is some helpful information: http://realbig.com/miata/miata/95-06/1047.html

Personally I am looking at this: http://www.seriousauto.com/bezel.htm but I am also looking for a Single DIN Blanking Panel and a Quarter DIN pocket. (Anyone have p/n's or URL's?)

I agree some sort of cover would be cool, and this is exactly what the author of the above message had installed - although it sounds like her cover was fully detachable, and I think a sprung flap would be nicer, kind of like the flap that guards the cassette slot in a player.

How possible is it to work on ABS? Is it easy to bend/form? Do you need special kit?

Whilst on the subject, which do people think is safer: face-off radios, or fully-removable radios? I can't help thinking that some stupid ****er would still have a pop at a removable-face radio even with its face off. (12/99)

Black 'foam' board is used by sign makers for cheap disposable signs .. it is lightweight, will bruise if you lean on a lump and you can mark it with your nails; it is solid not corrigated. However it is easy to machine/cut with wood working tools .. not a brittle as some Perspex etc when working with routers that move at 20,000 rpm..

I got a 12" square bit for 5 GBP from the local sign maker .. I suspect you could get it FOC if you tried hard enough.

Problems;
soft, ultimately brittle at high speeds, not easy to glue; ended up using industrial superglue with hot melt glue

Good points;
surface is low sheen black that matches the surround plastic, easy to trim with Stanley knife with patience, not really brittle

I mounted the stereo using the old double DIN brackets and then made a surround from the board to cover the gaps... this is screwed to the surround plastic with blunted 7g wood screws (all hidden). (12/99)

I have finally got to the front of the waiting list for an Empeg MP3 player, I would ideally like to fit it under my existing radio. there is a blanking plate there with a couple of switch blanks on it. Is there room behind that plate to fit a normal single DIN sized car radio? Can I get any sort of mounting kit to allow me to do this? Finally, are the Clearwater amps available from anyone in the UK, or in the US for that matter? I can't seem to find anyone selling them. (8/00)
Moss sell the clearwater stuff. There should be room for another single DIN unit under the radio but it depends on what is behind the blanking plate and whether you can move cables etc. out of the way. (8/00)
I'm having a stereo put into my Eunos Roadster and the fitter tells me I need a blanking plate because the hole is bigger than the stereo. Can anyone tell me if this is a standard Mazda part and if so what the part no. is? (9/00)
Part no is HE215235 00 and its official description is "ornament tuner" cost 31.41 unofficial description is "poxy little plastic tray that costs a ridiculous amount!" (9/00)
I used a cubbyhole from an old mazda - a 626? - local scrappy - cost 2 (1/01)
