Site Subscriber’s davebrads Posted July 19, 2020 Site Subscriber’s Report Share Posted July 19, 2020 BTW if there is anyone who wants to have a go at fixing my old Bose unit they are welcome to it, and the CD changer too. The aerial connection appears to have a dry joint inside the unit so that reception comes and goes (there are no issues with the new unit) and the cassette player has stopped working altogether. The CD changer has jammed but I think it probably just needs a bit of tlc. 3 1 Link to comment Share on other sites More sharing options...

Founding Member Retro Rich Posted July 27, 2020 Founding Member Report Share Posted July 27, 2020 Talking of Stereos, I decided to put the original Bose system from my previous Coupe into my current Coupe, as I'd like to keep it looking "Stock Original". I started by removing the Mexican built speakers in the boot and replacing them with the Bose speakers and then I decided to mount the CD changer in the same place as the existing one. Making more holes is not something that appeals to me greatly..... Moving to the front of the car, I removed the door cards and removed the speakers, replacing with the Bose ones. I took the time to clean the Cavities (it didn't need much) and squirted a load of wax seal into all the gaps I could find. (I would love a compressor driven wax gun with an omnidiectional nozzel ) but the aerosol will have to do 🙂 I also noticed the drivers door splash light lens has been damaged in the past and repaired with glue, so I'll try and source another. Lastly, I stripped out the dash center console and luckily all the original loom was intact allowing me to place the head unit straight in. Also simple, if not time consuming was the running of the CD changer cable to the boot. It's all been tested and sounds fantastic. I also managed to replace the clock bulb and that is working perfectly too. Very happy. Some pictures below... Also I have a question. The last photo is of a black box mounted in the boot with a coil or transformer inside. It's marked up TDK and that made me think of an audio crossover or something. Does anyone know? 4 Link to comment Share on other sites More sharing options...

Looking at the single conductor wire going into it Rich, i'd suggest it's the aerial amp/spliiter for the HRW/aerial functions. Could be wrong of course but it's the right sort of architecture.. 2 Link to comment Share on other sites More sharing options...

Andy Mc Posted November 28, 2020 Report Share Posted November 28, 2020 Has anyone tackled the dash mounted speakers/tweeters(?) And what size they are? I've chanced upon some small but substantial ones and wondered if its possible or worth swapping over. I know from previous experience they can deteriorate with dash and sunlight heat over time. 3 Link to comment Share on other sites More sharing options...
Torogo Posted December 30, 2020 Report Share Posted December 30, 2020 Hi Guys, decided to reinstate an original Bose fm radio cassette unit to my ‘99 V6 coupe in place of the aftermarket toy the last owner got fitted that didn’t actually work. Big oversight though, while the ‘new’ Bose unit powers up OK, I can’t get beyond the demand that I enter the security code. As it’s off a car presumed broken for scrap, I hold out little hope that the seller will know the code. Any clues if there is a way to reset it, if it’s marked anywhere on the unit, or indeed if it’s the car it needs to match to? Had completely overlooked this when I saw the unit on eBay, and not a big spend if I have to write it off , but thought I’d ask just in case there is a work-around. First month of ownership has seen the alloys powder-coated, ATF dump1 completed, underbody waxoyled, headlamps upgraded (as originally bought they were woeful, upgradedbulbs much better, though in truth still can’t hold a light to ‘moderns’) The car continues to run beautifully, and the doubters in my camp finally understand that a 20year-old ‘quality’ car, bought for peanuts is a fabulous alternative to the depreciation mules that everyone feels compelled to drive these days! Any clues on the radio code conundrum appreciated... ps was expecting to find a din connector lead in there from the auto-changer in the boot (based on a label on the head unit). Nothing found to connect though. Am I barking up the wrong tree?? 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted December 30, 2020 Moderators Report Share Posted December 30, 2020 Did you buy the radio off a dealer / scrappy? If so , longshot i know 🙄! may have the original books, the owners manual generally has the code at the front presuming the originating dealer their job. If it's a private sale still worth asking the question...don't ask, don't get !!!! re autochanger, do you mean the lead connection behind the radio or the connection in the boot ? 2 Link to comment Share on other sites More sharing options...

Glad to hear you're getting stuck into your coupe 😁👍 and FYI I have moved this to a dedicated topic since you're asking a question(s)? Also, I doubt your coupe had BOSE originally being a 1999 and probably just as well you can't get it to work ATM as it will need the BOSE speakers to work effectively. There's DSP built into the BOSE head unit which is matched to the speaker's frequency and power handling capabilities. Also, the BOSE drivers can easily damage aftermarket head units as they're very low impedance normally 1ohm. 😵 Either way, you will need its security code as Pete @PTR200S already said, they can be reset but you will need specialist tools and access to service data. I am guessing you purchased the USA BOSE version as the UK Accord is wired for six speakers or 6.1 in the hatchback which has a subwoofer, which uses external active crossovers and amps and it won't work in the coupe. 1 Link to comment Share on other sites More sharing options...
Torogo Posted January 2, 2021 Report Share Posted January 2, 2021 Aahhh, Looks like I’ve oversimplified things in my mind horribly😩 the Bose unit came from an eBay seller, and was advertised as from a coupe. It looks identical to the one in Pete’s pics, coming with the hlamp wash / hlamp height and blank panel below it. My car was registered sept’99, but as Stu picks-up with no Bose badging on the rear speakers. (My Mar’2000 5-door Accord exec had the Bose system from new, so I naively thought all similar aged coupes also Bose compatible😖) ref my DIN connector comment Pete, there is a label on the Bose head unit bought, that states the din plug is intended for autochanger connection only, but I found no compatible cable lurking in the dash cavity when I opened her up - there was though a multi-pin connector in there on a long lead connected to nothing, so maybe that was the earlier autochanger connection, thus not compatible with the Bose head unit. Think i I may be better seeking the advice of ICE professionals - I now realise reading the informed inputs from you two gents that the security code may be the least of my challenges in getting this up&running satisfactorily! (Btw i have contacted the seller - “all units tested prior to sale” suggests the PIN must be known to him? - we’ll see! - otherwise it seems there are online sources including Honda, that can advise the PIN from the head unit serial number once you’ve demonstrated you have valid reason to know. So; live & learn - in the short-term it still looks a whole lot better in there than the tatty aftermarket unit previous owner had fitted - & that didn’t work either! All the best for 2021 👍 3 Link to comment Share on other sites More sharing options...

Na just the year m8y, late 2000 it became an option and assuming yours are still the original, the pioneer speakers aren't too bad, despite the low wattage. 10 hours ago, Torogo said: so maybe that was the earlier autochanger connection, thus not compatible with the Bose head unit. UK Accord BOSE changer and cable will work with a BOSE head unit in the coupe, they're both Alpine units. 👍 1 Link to comment Share on other sites More sharing options...
KingK0ng Posted April 6, 2022 Report Share Posted April 6, 2022 My guess is no but if you don't have the Bose package have you the possibility to install the Bose amplifier or there is some kind of harness missing ? Link to comment Share on other sites More sharing options...
Administrators hughezee Posted April 10, 2022 Author Administrators Report Share Posted April 10, 2022 If your coupe is BOSE equipped which is usually 2000-2002 built cars all equipped with steering controls. Some 2000 or 2001 are 1999 built and won't have the BOSE system. Anyway, if you have BOSE and wish to upgrade my suggestion is to stick with the BOSE speakers and just replace the head unit, but don't fit another BOSE head unit from another Honda BOSE system, e.g CD player versions. Any aftermarket head unit will work fine and most standard ISO adaptors for 1998-2005 Honda's will work e.g Accord, CR-V. However, just make sure the orange illumination wire is disconnected or isolated from the car loom. If you are still after more power than your current BOSE system you will need to upgrade the head unit like with any other car and replace all the speakers & tweeters. Please note I would suggest bypassing the rear BOSE amplifier illustrated below. This powers the rear speakers and is only suitable for very low impedance drivers (like BOSE) it will struggle to power anything else. However, you could use the existing output for the speakers as the high input feature available on most car amplifiers and connect the new amplifier to the more powerful 6X9 speakers? If your coupe doesn't have BOSE my first suggestion in upgrading would be to try a Pioneer head unit as these have DSP or have speaker sensing built in so they will tremendously improve the sound quality and audible levels, despite the original speakers in most cases being less than 10W each. 🙃 If you are still after more power my suggestion is to upgrade like with any other car and replace all the speakers & tweeters. Maybe add a sub and fit suitable speaker or subwoofer amplification as needed.👍 If you want BOSE in your coupe, as in taken from another accord coupe which includes both front door speakers and dash-mounted tweeters and the rear 6X9 speakers. My suggestion is to buy and fit the matching BOSE cassette head unit too as this will be relatively stable on the low impedance drivers and will directly power the speakers adequately, compared with an aftermarket head unit. Please be aware there is no provision for the rear BOSE amplification (power supply). Although you can increase the BOSE speaker resistance by adding a series resistor (illustrated below) allowing you to safely use any aftermarket head unit linked directly to the speakers. Additionally, the use of other BOSE systems head units, these won't work unless it was originally intended for the coupe. The 1998-2002 Accord Coupe uses standard 1998-2005 Honda wiring from the head unit, unlike some other systems. I hope this info proves useful... 2 Link to comment Share on other sites More sharing options...
leyton72 Posted December 12, 2022 Report Share Posted December 12, 2022 @hughezee has given a very comprehensive overview of the Honda Bose audio system. My green coupe has the Bose speakers with the amplifier mounted in the boot as shown in the diagram posted by @hughezee and also the original cd auto-changer in the boot but came with an aftermarket head unit, I think it was a Pure DAB radio which was not connected to the cd auto-changer, it looked and sounded terrible, so I decided to source an original Honda radio. I bought one off Ebay thinking it would be the one that would go with the interior and also had the right connections for the cd auto-changer (8pin din), it looked in very good condition but did not come with the unlock code (what else do you want for a tenner!!!). I managed to crack the radio code (something I will share with you another day) so the radio was operational and fitted perfectly into the slot and looked factory finished. I then realised that other than the on/off volume knob, none of the buttons on the radio worked (only works initially when entering radio code), so I could not change the stations or bass, trebble, balance etc. However, when I put a cassette (miraculously I found one in my house) in to the player the sound was fantastic, luckily the eject button works. After trying to fix the radio for a week I gave up and decided to buy another one with the Honda Bose branding this time. It turns out both the radios are identical, the exception to the Bose is that it has a separate input for the Bose amplifier without which I will not get any sound coming out. My dilemma is that on my car there are no other separate wiring harness coming from the Bose amplifier, there is only one harness that houses all the controls and power for the radio. Suffice to say I cannot use the Bose radio unless I plug in the 12 pin connector for the amplifier which I can’t find in my car. If anyone knows how to get around the issue above, I would be very grateful as I don’t want to fit an aftermarket radio if I can help it. Below are some images of the two radios First radio_img1 First radio_img2 2nd radio_img1 2nd radio_img2 2nd radio_img3 1 Link to comment Share on other sites More sharing options...

As mentioned previously the CH7 UK 6th Generation Accord BOSE Head units will not work in the CG2 or CG4 USA coupes as these units are set up with 6.1 sound and the additional plug is for two additional amplifiers. So you will need BOSE 4.0 unit from a coupe or go down the aftermarket radio route, unfortunately. 2 Link to comment Share on other sites More sharing options...

I will try and give this a go in the new year. It looks simple, just a case of modifying/splicing into few cables. However the JVC's and Kenwood's will prove to be a bit of a faff, as they require specific programming with the AXXESS module. Currently have a Kenwood but might upgrade to a Pioneer DAB/CD single din unit. 2 Link to comment Share on other sites More sharing options...
Harry93 Posted March 12, 2023 Report Share Posted March 12, 2023 After years of having useless audio controls on the steering wheel, I finally managed to get them working again with my Kenwood stereo. I had bought the Axxess AXSWC module months ago but was just waiting to start fiddling with the interior again. At first had trouble getting it working as I was only tapping into the stereo harness, but after researching online, managed to get some further Honda wiring info. I guess I was lucky with mine, as the Kenwoods and JVC's require manual programming, requiring a resistor and figuring out the amount of LED flashes in order to figure out the fault codes. Trust me it is a faff, it almost convinced me to get rid of the Kenwood for something else just to make the installation more easier. But I am glad I took the time to get it sorted finally. Also there is alot of technical support on their website. I do have a spare module if anyone is interested, saves buying from the US. 2 1 Link to comment Share on other sites More sharing options...
