Rear door subwoofer fault

[marsie]

My disco(1999 series 1 v8)has a rear door mounted subwoofer but it dunt appear to be working.My car has been fitted at sometime with a kenwood head unit.I suspect on the standard radio there is a feed to the amplifier that isnt there on the kenwood
I have a spare plug on the car wiring harness that is a 7 pin flat chrome plug with only 2 wires connected(1 red,1 black)-Is this the amp/sub wiring plug??
On the kenwood there are 2(left and right)output plugs that are round phono type plugs
Is there a way to wire it up so the LR amp/sub works with the  kenwood head unit???
Ta very much

Without looking at it I wouldnt know, but connecting anything powered to a line out will nail the head unit. Can you get a pic?

After hours of mucking about trying to make my factory subs work after fitting a Sony head unit i gave up  :roll:
It didn't matter how i tried to wire it up, it never worked
So i just brought another amp and fitted a proper sub woofer.
Works a treat now although i have lost a sq ft of boot space
But, never mind eh

The two wires are indeed for the subs.

First your head unit must have RCA pre outs, if not you'll have to get a special adaptor.

Then you need to get hold of an RCA plug, say cut one off a set of leads then connect the red wire to the core and the the black wire to the earth/shield wire then stuff the plug into the back of the head unit 8)

You can pick up the converter for about £5 it has speaker wires 1 side & 2 phono's on the other

any idea where from?
My kenwood has 2 round plugs on the back,1 marked left 1 marked right very similar to the plugs on the back of a dvd player :? Are these the RCA preouts and if so is it as simple as wiring the red to the middle and black to the outer?? if so do i put it into L or R

Sorry if they are daft questions but car stereos are alien to me :-s

Yes they are RCA/PHONO plugs :D I can't remember how to wire them to speaker wires at the moment :oops: But i'll get back to you on it :D The convertors you can get from car audio shops, motoerworld & poss maplins
Hope this helps

Does anyone know where they sell a plug that has phono connectors on side and an iso the other. i too have a sony head unit that has phono outputs for a sub at the rear but i don't know how to wire it up or even if it can be done :?:

[SWEETY]

To be honest I don't know the set up on disco's as I drive a Terrano:oops: Sorry for swearing on your page :oops: I've built a few large sound systems over the years & have used a convertor when the head unit did'nt have RCA outs. The convertors have a tune screw for each side as different head units put out different power through the RCA's, eg standard headunit may put out 0.05 volts where my JVC one puts out 4volts. If you are fitting an after market amp things become easier as it's just RCA to RCA & then match the out put. Have a try at the places I listed before but if you have no joy i'll see if I can point you in the right direction to a surplier 8)

Hi Paul, which Kenwood do you have? I've got a KRC-379R and the sub-woofers don't work with that either. It's got a Kenwood KDC-C504 multi-changer fitted but that doesn't work at all  :x

[marsie]

its a krc 291 with 6 disc multichanger,not had chance to pull it out and have a look yet :roll: hopefully will get chance this weekend and let you know if i fix it :?

That lead has only got one phono connector but with my headunit I have 2 phono outputs, a red and a white :?: :?: :?:

[fordlltwm]

Red = Right pre out
White = Left Pre out 8)  8)  8)  8)

[cardiff_gareth]

Red = Right pre out
White = Left Pre out 8)  8)  8)  8)

yes but the lead only has one connector  :?:

[fordlltwm]

just pug it into either, you might just lose the sound on some mono stuff
