Hi I am new here having picked up my first discovery today, it is a 1993 model.
The stereo did not work when I bought it, so I have installed an aftermarket unit. But I have just noticed there appears to be a sub of some kind on the back door, is it possible to wire this in to an aftermarket headunit??????

Thanks Geoff

Hi Geoff, yes it is, if you find out how, could you let me know because I've tried all sorts of things and can't get mine to go :eek: ;)
 
So I guess I cannot simply wire it to the speakers, I am guessing it is powered somehow by the 2 extra wires on a plug of thier own on the back of the original stereo. :confused:
 
guy on ebeay sells the cable you need plugs straight into the wiring harness.

You need to have phono output sockets on the back of your new radio unit.

Take a plug and lead from this and connect to the two wires that go into the redundant ISO plug. This is basically what the Ebay guy is doing - but it didn't work on mine, maybe mine has other "issues" :eek: :eek:
 
Tried this today, mine did not work either. Took sub out of door, have got power to one cable but not to the blue and yellow. Tried powering this wire up but still nothing. Considering getting another unit to try.
 
I too the Blue and the Yellow out of the spare plug that you will find in the dash (The one that does the remote buttons), I then connected a Phone plug to those wites and plugged into the back of my pre-outs on the new H/U. The sub then started to work.
 
mine had a plug from the sub, got that adaptor off ebay wouldnt go, so chopped the wires and put a connector on instead, sub sounds ace now

Hi Simon, on my third plug there was a brown/yellow wire, a thin blue wire & a thicker blue wire - no combinations could make it fire up:(

I put some bookshelf speakers in the back from a little stereo I had lying around and they just work, nothing fancy but they work and that will have to do !!!!!

Thanks anyway. Don't you just love LR wiring, so consistant:rolleyes:

Hi there, what colour wires did you chop and where did you connect them to - the phono sockets on the new radio?? Please, pretty please??
Cheers for a reply as this is driving me nuts !!!!!

Cheers Dave
 
I only had two wires on this 3rd plug, so i just lopped it off and matched them, cant remember what colours they were (this was well over a year ago now) but thats all i did, i bought wanna them adaptors off ebay, and just ended up choppin the plug block off, connected the phono wires to the two the other wires i found, and the phono end went in back of the stereo. Have a looky in your haynes, and have a good reach round, it mighta fell down.

Thanks for that.

I found the plug, chopped off the wires and connected them to the phono wires - NOTHING !!!!

I bored with this now, all I want to do is listen to music and I can do that.

Thanks for the reply though, just got my grumpy head on, it's boiling over here and I suspect I'll not get much sleep tonight,

Cheers

Just another point, at first we had nothing, but we had to turn on the sub function on the stereo, they dont have them on by default

Hi M, I'm not 100% sure, but I don't remember seeing anything in the instruction book about sub-woofers on the menu sections.

It a Panasonic CQ-C1425N - anyone got any ideas???

I have 2 wires that were seperate they are one red and one black. I figure these are the ones to connect to the RCA. Am I right????
I have put power to the blue and yellow assuming it is the remote feed, the lilac/white wire is ignition live and then a black earth, nothing happens have I confused the wiring????
 
Oh god i dont know, depends on the make/manufactorer of the head unit, ours is a Tevion and had seperate menu's.
The sub has its own power, you've just gotta provide the signal to it if i remember the wiring correctly, no ones got a haynes? its like the last few wiring diagrams.

If your that stuck i'll get me haynes out/rip the stereo out

Hiya M, thanks for trying to help, but this thing has got me beat. All want to do is listen to music and I can do that with the present setup.

I've just had a look in the Haynes book of lies, and the wiring for post'95 cars does not correspond to the wiring in my '98 car at all.

As I said, I'm beat.

Cheers
Dave
 


On the standard LR setup there are three circuits to the rear sub. The 12+v amp power taken from the head unit supply, (light green/orange wire at the amp, also a local earth wire which is black at the amp).
The 12+v amp switching wire (purple/yellow at the amp).
The audio signal cable (black & white wires in a screened cable).

U do need a head unit with a sub output not all have that facility.

Regards

Hi Discool, thanks for your comments. My head unit does have left & right phone preamp-out sockets, so I thought that would be enough.

The black & white wires in a screened cable seem to be absent - I'll check again tommorrow, but I'm fast losing interest in this.

Cheers for your help tho'
