Hi All,

Ive recently purchased a cheap Chinese Head unit (Tuner, USB, Aux, Bluetooth) from the bay of the flea which I was intending to use in my daughters car.

However, Id like to add the above functions to the shed HiFi and this seems like a very cheap way to do it.

The enclosed instructions arent much use, so I thought Id tap the hive mind of uk diy.

The unit has 4 RCA sockets on the back (in addition to the standard Din power and speaker sockets), it claims these are two rear outputs and 2 rear outputs. I suspect its actually 2 front and 2 rear.

It also claims to want 12V power and to use a maximum of 15A.

IF I connect a relatively low output 12V bench supply (1 or 2 A from memory). And dont connect any speakers, but just use 2 of the RCAs to feed the stereo input of a HiFi amp.

1. Is anything likely to go up in smoke?

2. Is it likely to work?

3. Does anyone make a ready made case i coIll put it in and if so, what search term should I enter?

TIA

Chris

Hey, this *is* DIY!

Indeed it is DIY, but Im short of tuits.

But I have thought, I could get a second hand centre console from some car. Ill have to think which one.

This sort of bracket would do for under-shelf mounting, or possibly even turn it upside down

Well, it really depends on whether you know the pin outs and can block any
dc paths and know if any remote signals need to be terminated in a special
way to make the thing work. Don't car things these days have access codes as
they need to be powered up all the time to not lock themselves out. First I
think use some cables with capacitors in series and see what comes out and
when.
That is what I'd do if there is a shortage of English data.

My guess is it's probably OK - they must have thought about flat-battery-day
where the battery can't provide enough amps without the voltage sagging
badly.

However if you want a high current 12V PSU, get yourself a PS3 power supply
from ebay for under a tenner. Go up to 32A fanless:
https://www.psdevwiki.com/ps3/Power_Supply

Not sure about the best enclosure - I'm sure I've seen instrument cases with
a bezel on the front roughly the same size as a DIN slot, but possibly not
quite right. Make something out of wood?

Thanks for all the replies guys.

Ive done a little lateral thinking, and I think I should be able to pick up a scrap desktop PC with functioning PSU for next to nothing.

A little mollification, And I should be able to slot the head unit in the front of it, and the record deck will sit on top 11::^*))

Hi Brian,

It does have some English data, including where to put earth, permanent live and switched live.

Im hoping thats all Ill need apart from RCA out, and that it wont take much to set it up each time the power is turned on (dont have a permanent supply to the shed at present).

Hopefully if it has the option of a PIN, its not mandatory (hopefully they would have included some instructions if it did).

I recently bought a second hand Sony CD Head Unit for the car, and that just worked (aside of the fact it was initially in €œdemo mode€� Which included €œLOOK, I CAN FLASH ALL MY LEDS (IN CONTRASTING COLOURS) IN TIME WITH THE MUSIC!!

Be aware that the PSU may not work without a dummy load on the 5V

Hi Brian,

I dont think I need to do the stuff with capacitors, but can you expand on where you would have used them?

And what you would hope to gain?

(Not suggesting you are wrong, just seeking to learn).

A standard desktop one will. You'll find details of what pins to bridge to
fire it up etc by Googling.

Do remember many car radios need a permanent 12v feed for their station
memory, etc.

The other problem may be matching an external aerial to a car radio. And
it may have separate inputs for FM and DAB.

You might also have ground loop problems connecting it to a domestic amp.

That should be Power On,.

Power Good is an output from the PSU that
signals that the rails are up to spec now.

Cheers Dave,

Im not bothered about the tuner, its the Bluetooth and USB Im interested in.

The ground loop point is an interesting one.

Hopefully Ill get away with it.

I have in the past used a device (VHS?) Connected to mains via a 2 core mains lead and Its mono audio out connected to some sort of line in by just joining the inners of the RCAs together.

My mate said it would work, and it duly did!

I was really surprised!

Err, no ... that confirms that "power on" is green, short it to ground
(black) to turn on.

"power good" is grey, but not necessary to turn it on, merely an
indication that it has turned on.

A long overdue update.

I tried the head unit at the weekend.

I decided against using the PC chassis as a case in the end, and just put it on a shelf.

I realised I already had a 12V PSU feeding my turntable, so I tapped into that.

Worked first time. Only tried Bluetooth so far, that worked a treat.
