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

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.

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.
