Ok my amp has 4 channels each channel has a positive and negative terminal . Each speaker has a positive and negative wire hence you in theory should hook up each one of the speakers to a seperate channel

In theory i can therefore hook up 4 speakers to a four channel amp

i have 2 channels that are not working i have tried to hook up the speakers or sub to the faulty channels but nothing happens

So this is what i did install LR speaker to channel 3 and RR speaker to channel 4

I have a sub and in theory i would hook it up to channel 1 or 2 or if i want optimium perforamce bridge channel one and two for the sub (connect the positive sub wire to the positive terminal on chanel 1 and the negative wire on the sub to the negative terminal on channel 2. So what i have done is bridge the sub on channel 3 and 4 so this means i have both speaker wire and sub wire doubling up on some amp terminals

K that means your speakers and sub are getting close to nothing power

eg. 800Watt Amp 2 channels not working. Makes it a 400Watt straight away. This means that your speakers would be getting 100watts each and your sub would only be getting 200.

Depends on the value of your current amp. If its not that expansive then just replace it. I got a 4 channel 800 watt which i payed 100 bucks for and is still doing the job ;)

Or another option would be to run the speakers off the broken amp (on the 2 channels that work), and buy a monoblock for the sub. That would sound awsome :D

    • It can't be some stupidly proprietary video signal coming out of it that only Nissan's can understand. Surely you can just find some generic camera to stuff in there and use hot melt glue/blu-tac/gaffer tape to hold it in place if need be?
    • Update: Tunehouse looked into the problem and identified a wiring issue between the camera unit and the connector. They managed to get it working , but did warn me at some point it will stop working again. From their perspective it is unserviceable and will need replacement. They did some research and found that the new replacement camera would be Approx $1400 supply only (their fitting cost would be $190) . They did provide the part number (28442-JL05B) and a quick google of the part number shows that these are rather expensive brand new (seemingly no longer in manufacture) for the places that still have them in stock, with the used option potentially presenting  the same issue down the track at some unknown point. They are happy for me to supply the part so that they can fit it. Decisions, decisions... I can definitely recommend Tunehouse (thankyou Vee37!). Cost for the diagnosis was as quoted  ($190) , car was ready on time and communication was top notch. Their workshop is super clean and modern, and there was plenty of car candy parked out the front on the day I went.   Would definitely go back.   
    • to fix the voltage drop issue I swapped out the old 150amp alternator which turns out is a brand known for having issues and replaced it with the black 180amp alternator beside it 
    • For anyone interested, the Way Back Machine has that Japanese website archived with pictures, etc: https://web.archive.org/web/20051023225805fw_/http://www.a31cefiro.com/air_con.htm "Simply swapping the wiring of the harness will not allow it to function properly. For the outdoor air sensor and sunlight sensor, disconnect the wiring connected to CN1-11 of the air conditioning harness from the harness and connect the sensor side wiring to earth. For the indoor air sensor, disconnect the wiring connected to CN2-3 of the air conditioning harness from the harness and connect the sensor side wiring to earth. The connector PIN numbers listed here are the genuine A31 PIN numbers. To avoid incorrect wiring, check with a tester before wiring. Also, disconnect the wiring in a location close to the sensor. The disconnected harness side wiring will not be used, so be sure to insulate it." Wish someone sold a conversion harness to just plug-and-play a Kouki 180sx digital climate control into C33/A31. I'm decent with wiring but feeling kinda lazy about taking this on. Edit: Did some more digging and found a helpful Minkara blog post about the conversion as well: https://minkara.carview.co.jp/userid/1831116/car/1360568/2284209/note.aspx "After installation is complete or the battery is replaced, you need to go into self-diagnosis mode and set the internal air recirculation. The way to do it is to "hold OFF with the key on for more than 5 seconds, set the number to 5, then press 卍→C." ↑↑↑It probably won't make sense unless you actually try it (・∀・)." Lol wtf
