Hey all

I plan on fitting an Alpine CDA-9886r to my 147 GTA.
I've fitted my own radios before in my previous cars with relative ease, so I know what i'm doing.

Is it as straightforward or is there more involved in fitting this unit to an Alfa? What tools do I need to remove the standard HU and what do you guys use as a surround for the Alpine radio to make it fit the dash so nicely?

Ive seen some pics on the forum and they look so good :)

it's quite straight forward.

note the 2 holes on either side of the factory headunit. you are meant to use specific 'keys' to insert, which push aside metal retaining tabs that stop the headunit from coming out.

the keys are cheap, but you can also use wire, like a metal coathanger. takes a bit of patience, but push the metal in, then grasp the front edge of the headunit, and pull. jiggle the metal wire until each side is released and the headunit can be pulled out.

if you can't grasp the edges very well, you can first remove the cup/cardholder underneath, then reach behind the headunit to push it out. cupholder unit is clipped into position; first extend both drawers, grasp them in your hands, and gently but firmly pull. when it unclips, it can come out in a rush, so brace yourself.

for wiring, you'll need a wiring harness with matching ISO plugs to connect to the alfa ISO plugs. note that wires #4 and #7 in the alfa are 'swapped around' compared with standard patterns. if the alpine comes with the harness, the relevant wires will have bullet terminals that you can easily switch around. wire #7 in the alfa power-ISO plug is the 'constant' +12V powerwire (= main powerwire); this must connect to the YELLOW powerwire feeding to the alpine.

if wire #4 exists in the alfa plug (not all 147/156 have it), it will be the IGNition/ACCessories wire, and connects to the RED wire to the alpine.

if it doesn't exist, the RED alpine wire can connect to the cigarette lighter power which is 'switched' (0V with ignition key OFF, +12V with key ON).

for the steering wheel controls, you'll need to modify the connection. the 3 alpine wires need to connect to the 3 equivalent wires in the alfa GREEN mini-ISO plug; refer to the schematic atop the factory headunit, but the wires are RC-A, RC-B, and GND (has ground symbol).

you'll need a dashkit, which is a plastic fascia piece to surround the new rectangular headunit. anthracite colour is uncommon, but exists (as opposed to the more usual silver). you may wish to respray a silver one if you can't find anthracite (i presume your GTA has an anthracite dash).

the alpine rectangular surround trim can clip over the top. my own dash looks 'one piece' cos i modified it with bog/filler, sanding/shaping, and respraying.

if you have Bose, then you will also need to connect the alpine's remote output wire (BLUE/WHITE) to the lead in the alfa YELLOW mini-ISO plug. this triggers the Bose amp on/off. also best to use the RCA preouts for audio signals, and connect them to the alfa speakerwire-ISO plug. in this situation, get hold of a nexxia adaptor, the PC2-36-AMPR. http://www.nexxia.co.uk/Car_Stereo_fitting_kits/Alfa/147.htm

On the 147 there is no yellow wire on the alfa ISO.. just to warn you.

May be on yours :)

no, no :) . i'm not referring to a yellow wire in the ALFA plug.

my reference to a yellow wire is in the ALPINE wiring harness. virtually all aftermarket brands use a yellow wire for the 'constant' +12V powerwire. this needs to connect to wire #7 in the alfa ISO plug - no idea what colour that wire is.

Are all the Alfa 147 dashescoloured anthracite or are some silver, as Icouldn't tell you which mine is?

any ideas as to who may supply the correct anthracite dashkit?

Cheers,
Brian

GTA is anthracite. normal 147 is silver.

not sure about various limited edition 147's (eg: Ducatti or Q2).

have you contacted nexxia about buying an anthracite one?

anthracite is a dark metallic grey. if you're unsure, post a photo of your dash.
