Thanks. I'll confess to not having looked at it at all, but I vaguely remember reading something about the sub being a special to match the head unit and didn't know if it had some sort of unusual connector. Darren

I have the same issue, Darren.
The Alpine head unit has twin RCA connectors to the sub and a remote cable connection that switches the sub on/off with the head unit. The JVC has a single RCA out to the sub. Something similar to the below sorts the first issue:  But I’m thinking I may need to ditch the remote and wire the sub with manual on/off.....I’ll check again as am planning to sort this and the camera this weekend.

Ah, I'd be really interested to know how you get on with that.
I guess if it's just a 12v signal to turn it on then any old ignition live would do? Darren 110 USW BUILD THREAD - EXPEDITION TRAILER - 200tdi 90 BUILD THREAD - SANKEY TRAILER - IG@landroveranorak "You came in that thing? You're braver than I thought!" - Princess Leia |

On most head units there's a switched output to allow controlling subs / aerial amplifiers / electric aerials etc. Off the top of my head it'll be a blue wire...

Just a word of warning. The blue / white wire mentioned here is known commonly as the RMT (REMOTE.)
As has been mentioned, it's purpose is to turn on audio devices as a signal not a power source. Thus, it have a very limited load capacity around 300mA max. (Typically.) It also should be fused at about 250mA nearest the HU to protect the inner circuitry etc. Especially if you have a HU worth quite a bit. 
It will switch a single Amp on no problem, you could probably just about get away with two. Beyond that don't do it, you'd then need an ignition 12v fed dedicated supply using the RMT. as a signal switching feed only for the relay coil. You'd also need a dedicated circuit as mentioned above if you wanted anything else powered so your HU effectively becomes an automatic switch. Regardless, I would definitely fuse this feed at the HU rear in-line. You can use a fused ignition 12v instead if you want but your Amplifiers will be on all the time the ignition is on. Including during the start up process of the engine and that won't help the starter, voltage drop or be great for the Amp(s). Really you don't want any devices powered up during the starting process, after all you wouldn't and shouldn't turn your lights on before starting the engine.. That way you are putting cull CCA from the battery to the starter. Particularly important in cold weather.  ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️ |

Hi Sandy,
I’ll ask the installer. I went with his choice of camera. In case you can find it with Google- here’s a close up pic: Click image to enlarge |

Finally have the camera details. It is this one:
https://parksafeautomotive.com/shop/ahd-rear-facing-camera/ I did not buy them myself. The installer sourced them. So far they are perfect though.👍🤞 |

Hi Ian, How did you get on with this? I've just been gifted one of these head units for my birthday and so will need to solve the problem.

Ihod - that looks really good!
I've got a standard camera fitted at the moment, what's the image quality like on the Optimill unit? Can you see the tow hitch? £15 Amazon camera mounted on drivers side roof gutter:- Click image to enlarge Click image to enlarge Sandy |
