hey everyone,
first i am not great with electrical wiring- it’s a foreign language to me.
i recently purchased the cassette am/fm radio (volvo 4 stereo esd) to replace to AM that came stock in my 79 242.
problem i have is there’s more wires coming out of the back of the new radio than there is that came out of the AM radio.
do i just need to connect the antenna, ground, power, and speaker wires and nothing else or is there something else that i’m missing here?
sorry i know this should be common knowledge.
thank you in advance

Hiya,
Välkommen to the Brickboard RWD forum!!!
The model name "volvo 4 stereo esd" represents some dozen or more models from the extreme late 1970s and well into the 1980s.
What Arty B. shows you is one of many models of "volvo 4 stereo esd". On the labeling do you see a part number or model number as Art shows with the model RX-2Q Cassette?
The 4 in "volvo 4 stereo esd" means left right stereo that plays through some manner of fader control on the radio (yes) or is a dash mount accessory (probably not). The stereo may include an 8-track or cassette tap player.
Such a vintage mechanism, such as tape transport, may need at least inspection or preventive repair so a tape you play does not get eaten.
In this sales page, you see a box secured at the back of the radio housing. The box contains a line level to speaker power output amplifier. The box secures to the back uses a DIN plug interface from the radio line level output to the attached power amplifier. An integrated head unit / tuner / tape player with power speaker out. Copy and paste URL into new browser tab or window.
https://www.volvo340onderdelen.nl/en/radio-klassiek-model-volvo-300-serie-copy.html
Label
Power amplifier bolted to the radio rear:
If your "volvo 4 stereo esd" appears without a box, yet four sets of two pair wire here, whether terminating into a connector or merely the wire ends are cut or each have a bullet or like connector, indicates the stereo and power amplifier are integrated.
I used Google to search all and images for "Volvo 4 Stereo ESD" and check the images. Bing search and image search will show somewhat different results.
Can you record and post images using the brickboard BrickPix GALLERY? Or use your fave (Not Photobucket) image hosting site. If you cannot link using the img src tag, one of us can. Or merely past a link to see the images. As Art documents in bright and happy:
Also, for the rear left and right speakers, you can install these in the rear hat / parcel shelf. Secure the speakers to the fiber board and secure the rear hat / parcel shelf with dampener mat so the fiber board does not vibrate against the sheet metal.
As the "volvo 4 stereo esd" outputs to four speakers, you'll have to run speaker wire top the rear speaker you'll install in the rear hat / parcel shelf.
Rear hat shelf images in my 1992 240. The speaker hole are there already as the factory speakers were not present. Used 5.25" or so speaker, used hardware to secure to the rear hat shelf. See the hex head bolts securing the rear hat / parcel shelf to the sheet metal. No, I did not in any cut or alter the sheet metal.
Car left rear side speaker:
Car right rear side speaker:
The wire harness already includes rear speaker wire to the rear hat shelf. You may find a rear hat shelf with factory speaker cut outs an save your factory installed hat shelf.
Else, dunno what else to research and say here. 242 is my fave 240 model. Lube them door hinges! Heavy doors and the hinges work best lubed. I use a tub of white lithium, yet you can use silicon (SuperLube). At 40 years, you'll have a host of service work to do if not performed already and documented! Rear wheel / axle hub works including bearing grease pack and parking brake shoes, and so much more!
As you say wiring is not your thing, you may want to enlist a 'professional stereo install service'.
Research professional quality as radio install service quality shall vary wildly.
If this "volvo 4 stereo esd" has not been serviced or restored, there exists a few restoration services that are expensive.
The "volvo 4 stereo esd" uses an L-shaped bracket to support the radio rear weight in the lower larger cubby. The radio chassis body may be large enough to alternately secure at the sides through oblong hole in the lower cubby box. The screw you use must be short not not exceed the max ingress if indicated on the chassis box.
At the Oz Volvo archive (https://ozvolvo.org/archive/), there is a 1979 accessory catalogue. Yet no real support for the 1979 model year. 1977-1980 240 with four cylinder engine have more or less the same wire harness in the US Market.

Your post got me curious as to the Volvo 4 Stereo ESD so I did a bit of digging for you. I couldn't find proper wiring diagrams for it, but did find enough information to help you.
The stock AM radio in your '79 240 was a 2-channel (L-R mono) AM-only radio with mechanical presets. There are 6 basic wire connections off the back: 4 for the two speakers (colours?), one for 12V in from the ignition switch (Blk, unusual for a black wire not to be ground), one for ground (Gry), plus the antenna cable. For a power antenna in your vintage of 240 there are two possible connections: a) a separate Blk wire off the radio (off the side corner?) that is used as the up signal for the antenna mast motor (only present when the radio is powered on), or b) having the antenna motor operate with the ignition switch through a separate dash up/down over-ride switch (independent of whether the radio is on, there is then no antenna motor wire on the radio).
The Volvo 4 Stereo ESD was the premium sound system option available for 240s of that era (standard on the 260?). There was also an optional graphic equalizer unit available for it. There were a few variants of the Volvo 4 Stereo ESD. In North America it appears only the AM/FM/Cassette 4-channel version may have been available, but I see other variants, including a 2-channel stereo and ones for other radio bands used in Europe. The wire colours may be different, but the wiring principles are the same. There is both a full time 12V battery connection (Grn?) and an ACC+ 12-volt supply (Yel-Blk?) from the ignition, plus of course a ground (now Blk?). Four of the extra wires you haven't identified on the back of your ESD will likely be for the pair of rear speakers you probably don't have. In addition to the antenna motor signal (Red?), there may be an additional wire present for dimmable dash lighting (Blu-Wh?).
Now, unfortunately for you, while the AM radio had a built-in amplifier, the ESD appears to require a separate amplifier. The speaker wires out the back are unamplified signals and require a boost to drive the speakers, so from that standpoint you're a bit screwed if you didn't get an amplifier unit with your radio (would have been buried somewhere under the dash). It would be possible to now add a different amplifier, but likely not worth the effort, especially if electricals are not your forte. If you're simply looking to upgrade your AM radio, check out Crutchfield.com who also have the needed 240 dash mounting kits.
You can find a description of the Volvo 4 Stereo ESD here on pages 6-7 of www.volvotips.com/brochures/240-260/1981/Volvo-240-260-accessories-1981-USA-brochure.pdf
Also on Volvotips is an assortment of Volvo green manuals, including the wiring diagrams I used to decipher some of the above.
NB to all our users here: Copies of the Volvo green manuals and some other valuable documents at Volvotips.com require the now unsupported Adobe Flash Player browser plug-in to view them on a page by page basis.

Unofficial copies of many, but not all, of these green manuals can be found elsewhere on the web.

so with this being said- almost positive there is no amplifier under the dash.
could i source an amplifier, and be able to use it that way?
thank you everyone for your replies and help!!

Yes, the Australian Volvo Club is one of the better resources exactly as you mention, albeit unindexed with many obscure file names. There's also a couple of good sites in Europe, some are foreign language but have English manuals. Google often doesn't find them, leastwise not easily. I always hate to mention specific sites except in general terms because Volvo used to have a habit of threatening legal action against site hosts if they didn't take the copyrighted manuals down forthwith. It's hard to imagine Volvo caring about the old 140/240 manuals, even the 700/900 ones, but somes of these sites have manuals for Volvos actually built in this century. Although I usually buy the proper green electrical manuals from Volvo as they are so useful to me in paper form, for everything else I always try to download them rather than bookmark them. I keep meaning to weed my bookmark collection of assorted Volvo sites that after all these now has tons of dead links. I'm now using one of my older iPads to hold green manuals that I can take out and use under the hood and under the dash without fear -works extra well in a dark garage.

Asked Volvotips site owner to convert .SWF Flash File to HTML5 or MP4 several times in the last five years. Reminded him .SWF Flash file support is at the end.
The quality of the Volvo docs scanned to PDF and then converted to .SWF flash files is a poor quality. The site is terrible and overstates the actual content available.
No response or change by the Volvo Tips site owner. It next to never I use it for myself or as reference to other Volvo owners.
The OzVolvo site is no k-jet.org. Stupid me for not collecting his PDF files and storing locally someplace. I then had the storage in Mac OS 9.2.2. Would have contributed to the OzVolvo Archive.
Many sites exist making Volvo docs, scanned to PDF, available in Sweden and other nations. They remain open. I'll continue to post links to files here, at other Volvo enthusiast sites, and in email.
I guess metch92 is unable or unwilling to provide more detail about his 'Volvo 4 Stereo ESD'.
Someone please tell me where the heck is Uncle Old Duke? By now he usually posts here with his commentary I find joyful. I'll get worried, research, and post incorrectly. Maybe I'll ring him.
cheers.

There was another same named individual in the same region as where Uncle Old Duke resides. I was then wondering where Uncle Old Duke was as he seemed sort of late at the start of the cold months when he returns to his 1992 240 Wagon with M47 II as his primarily motor vehicle.
Uncle Old Duke drives Saturn with cold A/C in the hot and humid Florida warm months.
So, yes, I'm rather concerned. This unneeded pandemic compounding my concern.
I've not ever phoned Uncle Old Duke yet not hard to find what I guess is his phone number where he live in FL-state.
I'll be glad when Uncle Old Duke begins his cold months of posting here to our brickboard!
Thank you. Hope all ya'll are safe, happy, and healthy.

Hi Metch,
Välkommen to the Brickboard!!!!
Snow? Motor safely, please!!
RX-93UK! Thank you.
The RX-93 UK offers AM, FM stereo, and an auto / manual reverse stereo cassette tape transport mechanism. RX-93UK uses a bolt-on integrated amplifier secured to the back of the chassis. The amplifier outputs to left and right speakers as a two-channel amplifier. No fader feature to for rear left and right speaker connection. An external fader that mounts to the row of center console press in controls where you have the hazard flasher switch, rear demist (back glass defrost). (I have this fader someplace, I guess. Unsure.)

Click the SOLD atop the radio image in the blue box at the page top to open the ended auction. Sold in Medford, OR for 160$ US.
I found two diagrams for a radio circuit in 1997 imprint Haynes 240:
- 1997 Haynes 240 p12-22, 1976-1979 Radio (No wire colors)
- 1997 Haynes 240 p12-27, 1980-1983 Radio (Shows Wire colors, with wires out of the radio, a connector, intermediate wires of a different color, a connector, and different wires at the left and front speaker. No rear speaker wires.
Colors don't match. Yet the harness that should be connected to the wires terminating in the connectors on your radio are not there.
You can see the connectors and on either side the conductor color changes. Yet is a two speaker radio. No rear speakers. Some detail may be missing.
The image is 900 pixels wide here to fit into the main text flow column on page display. The actual image is 1576 pixels wide.

Here is a link on the same radio model of your posted by muskox37 this past June 2020.
https://www.brickboard.com/RWD/volvo/1673296/220/240/260/280/radio_cassette_schematic_wiring_diagram_available.html
Did not read through it all, the found the above image for Mr. Muskox37.
I'm unsure about the wires coming out. The black and black yellow wire are left and right speakers. The other single conductors in red, blue, black (ground) and light blue (power aerial?). You may need to figure the ground, power, and other single wires to connect to a fused 12 VDC power, turn on the radio, attach a small speaker to each of the black paired wires, to figure out what is left and right. Don't short any of the wires. Only the black single wire connects to the metal frame under the plastic kickpanels and section surrounding the center console.
I'll guess you have some testing to do. Nice winter project! Yet watch the interior plastic section as they get brittle in cold weather!
Questions?

Pleezed to halps!
Wondering whether your Volvo 4 Stereo ESD model RX-93 UK has undergone any sort of restoration like you see the label on Art's Volvo 4 Stereo ESD images?
Sorry to obsess. Futzing with stereo's in RWD Volvo can be painful. The stock interior the 4" shallow speakers in the front doors. The tone range and watt output limit of the Volvo radios like yours made by (I guess) Mitsubishi and 1990-1991 made by Alpine with the separate amp. The sort of terrible Dynaudio paper cone speakers that have those offset, not square, speaker screw holes.
Though I understand you want the original, from the factory appearance. It can help a tape cassette / stereo radio from the 1970s to have an inspection and service for the tape transport mechanism (else may eats your tasty cassettes with tasty music on the tape!). An idea-r.
When you swap out the Volvo Am Radio, screws secure the side of the radio chassis in the radio cubby slot. Sorry to repeat, yet you need to support the back of the radio somehow.
Glad that helps, yet please continue to verify wiring configuration.
What how about your door speakers? Are these original also?
Sorry to go on.
Glad that halps.
Where's Uncle Old Duke?!?!?!?
Great heavy aluminum alloy speaker enclosure made for Volvo. Though by now you have to replace the three paper cone speakers inside, and maybe the cross over capacitors! Sound great, yet no-wheres to go. Use them as in-apartment speakers occasionally. Yet in-awful-smelly-vermin-filled-apartments-dumps in cities like terrible Saint Louis, MO, all headphone all the time.
Have these in my 1990 (made in 1989) 240 (li'l red) Wagon in C-pillar!
On the same wires, wired in parallel (reducing ohms resistance load) to the rear door speakers in the li'l red wagon.
May rout new wire through the driver door today and reinstall the after market CD receiver head unit. Found the bracket Volvo uses to support the rear of the radio weight. When I got this 245 in 2004, the radio weight was sitting on the coolant lines and wires inside the center console dash! Turrible!
Happy Pandemic Hollow-Dayze.
Don't blame me, I voted for Finland and Switzerland and Norway and Canada!

yes. everything else is stock. i acquired her in june of this year and have been slowly working at restoring her.
it has not been serviced, maybe that’ll be my next project is to find someone who can look at it.
and yes i have the super old and tired speakers that frankly a sponge might sound better.
any suggestions on speakers as now that is probably my next upgrade for inside the cabin

The UK version of this unit only goes up to 104 on FM. That's because services like the police were using frequencies between 104 and 108. USA models went to 108. The 108 models are now better for the UK as those public service frequencies have been changed, with those using 104 to 108 for public service communications now being elsewhere. 104 - 108 now packed with stations just like the rest of the waveband.
