Hi.

Got a question for you all. I have become quite frustrated and need
direction. Here goes:

I have a 2003 Hyundai Sonata LX with Premium Sound (Cassette and CD).
I bought a JVC KD-DV5100 Deck.
The Deck came with an HWH-1102 wiring harness.

I wired everything up correctly and there really are no shorts (so
please don't go telling me I have a short, unless you are just making a
joke at me ).

The deck turns on and functions correctly. The CD plays, the FM Tunes.

***No Sound comes through speakers***

When I put my old deck back in, sound works fine.

NOW HERE IS THE INTERRESTING PART:

Counting the wires in the harness that is physically wired to the car,
there are 15 wires. I looked on Hyundai's site for any information as
to explain which wires are for what systems in the car. Not any good
info there that is readable(www.hmaservice.com).

Counting the number of wires coming from the HWH-1102 harness, there
are only 14 wires.

This means one wire in my car is not being connected to anything when I
use the adapter harness.

I am now at the point where I believe this one wire is the reason my
speakers are making no noise when I connect the new stereo, but they
work fine when I connect the old stereo.

The wires that I have connected from the car are as follows:
Left Front Pos
Left Front Neg
Right Front Pos
Right Front Neg
Left Rear Pos
Left Rear Neg
Right Rear Pos
Right Rear Neg
Ignition Power
Battery Power
Ground (Black)
Power Antenna
Illumination Control
Dimmer Ground (I have been grounding this wire, as the deck does not
have an input for this wire.)

The wires from the deck that are not connected to the car system a
Parking Break (I have this grounded)

I am going off of memory, but I believe that is all the wiring info.

So to reiterate:

The new deck works fine, except no audio comes out.
The old deck works 100% fine.
The old deck receives 15 wires from the car.
The new deck's adapter harness only receives 14 wires from the car (one
wire is not connected)

Does anyone know what this mystery wire is, and is this what is causing
my pain and suffering?

Sincerely,

Nathan

Your vehicle may have a factory that is not being turned on, or you have a
speaker wire grounding out.

Thanks for the reply. I know it's not a speaker wire, so what do you
mean "a factory that is not being turned on"? I'm not sure what that
means. Do you mean a factory amp?

Your car may have a factory amp the is not letting the signal get to the
speakers. See if that American International harness has a "amp remote" wire
and hook that to the amp remote wire on the JVC. Some of the JVC's only have
1 remote wire that does both amp remote and power antenna. If it only has
the one remote output hook that to the amp remote on the AI harness

No, the HWH-1102 does not have an "amp remote" wire.

However, this does make sense, as one wire is not being connected, but
the adapter I got (HWH-1102) does not have a male plug inside it to
connect to the adapter in my car (this must be the amp remote wire). I
suppose I can try and manage it with just a wire, being thread through
the adapter into the other adapter. May not be sturdy, but will let me
know if that is the problem. I'll let you know.

Thanks for the help.

Nathan

So how did you determine that the extra wire is for the parking brake? Why
did you ground it? Is it an input to or output from the radio? Do you get
a voltage there when you apply the parking brake? If not, it probably goes
to an output from the radio.

I can't imagine why an output from the radio would have anything to do with
the parking brake. If this is the only wire not connected and no sound is
getting to your speakers, I would strongly suspect it is a turn-on signal
for the factory amp, in which case it would probably need +12V from the
power antenna or remote output from your aftermarket HU.

You can confirm that you have a factory amp by measuring resistance between
+ and - of one of the speaker inputs. If you get something around 4 or 8
ohms then there is no factory amp. Otherwise there is. If you don't have a
multimeter, just briefly put the + and - of a small battery to the + and -
of one of the speaker inputs. If you hear a pop from one of the speakers
then there is no factory amp. Otherwise there is.

You can also use a test light or multimeter to see what happens to the wire
when you plug in the factory radio. If you see it go to from 0V to +12V
when you turn on the factory radio, but it doesn't ever do this when the
wire is disconnected (with ignition on/off, brake on/off, etc), connect it
to the power antenna/remote output from the new HU and I bet you'll get
sound.

Parking Break (I have this grounded)

Sorry, I misunderstood you. I thought you had somehow figured out that the
mystery wire from the car had something to do with the parking brake. If
it's truly a mystery wire, just make sure it doesn't ever get driven high or
low on its own using the methods I described before, then connect it to the
remote out of the new stereo and see what happens.

Thanks Jason. The problem was that wire. The Factory Amp (which I
didn't even know I had, hehe) had a remote lead that the adapter for my
car was not connecting to. The hole in the adapter was there, just no
wire running through it.

So to fix this issue, I took one of an ISO connector's wires
(butchering the connector as I had no need for it), and ran it into the
HWH-1102 in the hole that should have been connecting to the car's
remote amp lead. I then split the antenna/remote lead coming off of
the JVC deck to fead both the antenna lead of the car and the remote
amp lead of the car (the new wire).

I grounded the parking break lead to the chassis so DVD playback works
while in motion, but now it appears my dimmer ground is not correctly
grounded (I grounded this to the chassis too, but I guess I should have
grounded it to the negative ground on the battery). I'll fix that when
I install the touch panel LCD monitor in my dash

Thanks for your comments.

Does the deck have an antenna AND remote lead? I think it's slick to have
the antenna up only for radio listening

I had the same problem as you but even a bigger DUH! I tied the remote to
the antenna so my stock speakers would only work when the radio was on.
Worst part is that I tested it out of the das with the radio as I was
replacing a stock deck with no CD and had no media in the car. When I
finished it was dark so the next morning when I carried out a CD to drive to
work........ DOH!

Weird thing is that in '95 Mopar used the infinity amp to power the woofer
and the tweeter still runs off deck power... the CD had plenty of highs .

Do not hook the dimmer wire up to ground. Disconnect it and tape if off.
that could cause you to burn out the dimmer circuit or blow a fuse

Chad Wahls:

Yeah, my friend did that too (swapped ANT and Remote leads) and had it
all installed and did a big DOH! This deck only has one remote/antenna
lead But otherwise is a good deck..

joe.ker:

no, it wasn't the "dimmer" wire it was the "dimmer ground" wire. the
dimmer wire is labeled "illumination". So I haven't done it yet, but
it seems that that wire actually should be wired to the ground. Am I
still wrong in my assumption? Thanks.
