You don't want to fit that - it's the factory amplifier for the rear speakers (the rears are amped, the fronts are not). You need to run new wires from the head unit back to the new rear speakers so that the speaker-level outputs from the new head unit are used to drive the new speakers.

SOURCE: Radio wiring problem 2001 Audi A3

Hi, had total issues with this too! Your back speakers arent going because they are amped by the factory amp in the boot. You have to provide power to the amp so that it will turn the rear speakers on. This was a white and black striped wire in my car (Audi A3 1997) The rear speakers are blue /green and brown/red (left rear) , and the LH rear is brown/red and (forgotten colour) but the wire on the bottom left under those two brown/red wires on the 20pin harness. If you wire it all up like this then your rears should be going :)

Testimonial: "So sorry for the very long delay in replying to your advice. It was the sub/amp in the boot as you correctly guessed. Another £200! Many thanks Pal"

Anyone know where the radio antenna is located in a 2008 accord estate. Old type. I have very poor signal at times lately. There are wires in bother side windows as well as the rear.


The aerial is within the rear windscreen heater and there is an aerial amplifier that sends the RF signal to the radio. They can fail.

I have static in the radio when I turn on the rear defroster.


The rear screen heater is a pure resistance being fed with direct current and normally will cause no radio interference as it does not vibrate or oscillate, though a loose or dirty connection or dirty switch could produce interference.

Some cars use the rear screen as a radio aerial and these are prone to producing radio interference, especially when trying to receive vertically polarised signals.
I tried this myself using a bi-fi rear screen aerial adaptor and was very disappointed with the results, the signal-to-noise ratio was appalling.

If your car uses the rear screen as an aerial there is likely to be a box of electrickery physically somewhere near the rear screen where the aerial cable originates. This box contains stuff to decouple the radio signals from the HRW circuit and will probably contain a signal amplifier.

The static you hear might just be a drastic reduction in signal strength rather than actual generated interference. You can do little else but to check the connections to and from the unit particularly the ground connections and check the voltages present on the related wiring. If no external faults are found it is likely the box of electrickery has failed.

Spending a while looking at dedicated forums might help further.

Radio all works but no sound


Without more details (new install? other inputs provide sound?) just guessing.

Possibilities:

Aerial disconnected if only radio sound missing
Speakers not connected, or not connected properly (mixed up wiring)
Amplifier in radio faulty

Took my q7 to a garage to have a drop down DVD fitted, now my radio channels keep dropping out its like the aerial is only half working and the signal is really weak. I have checked the obvious things like...


Are you sure they plugged the antenna back in to the radio head unit? You need to remove the radio, check the back, there is a thick black cable (not fiber optic) that plugs into the back. Be sure it's in securely.

Just fitted a cd/radio to to my 03 fiat punto. the cd player works great but the radio is rubbish,terrible reception no matter what i do. the correct connection is in the back of it. i love the radio. help...


This may not be very easy. Presuming that the aerial cable was already there and there was a standard plug on the cable that fitted into your standard socket on the radio, and presuming that you are confident that it all fitted OK, then the problem is with a faulty cable or aerial.

Just before you start, can I suggest that you DO test the radio and check that there is no fault in it. Particularly if you have removed an old radio with perfectly good reception. You might want to take it back to the shop and ask them to hook it up and test it for you. If the radio is clearly good, then my thoughts are as follows:

Typically the fault will eventially trace down to a portion of the outer copper brading in the cable being in contact with the inner core that carries the radio signal. This is usually right at the end in the plug and it's worth cutting off the plug and refitting a new one as a first step (You might even be able to carefully bare the inner core of the cable and push it into the cernre hole in the socket of the radio and test it before the new plug is fitted).

The second area of failure is typically the point at which the cable reaches the car aerial. It's not uncommon for water to get into a seal wher it is attached to the body and affect the performance of the aerial. Once again, you MAY be able to snip the cable at this end and re-make a nice clean dro connection. I have to be honest and say I don't know how the fitting go in this vehicle, so I'm shooting in the dark a little here. Obviously, if the vehicle has a built in aerial in the windscreen or back window somewhere, then my last suggestion is pretty redundant.

Finally, having tried to re-make connections at both ends of the cable, it's potentially time to buy a new aerial and cable and re-fit the whole thing from end to end. This is not a very fun job!

Rear-window defogger wont work and radio cuts off when u put on


Sounds like a dead short. Disconnect the power to the radio and try the rear defog. Then to determine if it is the radio or the hater, disconnect the heater and put power to the radio. Another simple test is to, at night have the head lights on, turn the radio on see how much the lights dim. Then with the radio off, turn the rear defog on. Then try both. IF either one makes the head lights dim and not recover after a minute or so that devise is the shorted component. Check grounds on the radio and the heater.

MY FACTORY RADIO VOLUME PROBS


More than likely with a 2003, the speakers that cut out are in the door or doors. Do they cut out of both speakers?

If they cut out of one, then you may have an intermittent speaker ( the wire to the cone becomes partially connected)

If both speakers turn off at the same time and you hear NOTHING on all speakers, then you more than likely have an intermittent connection on the radio itself and probably replacement is probably cheaper than fixing the radio.

One more thing
Factory radios sometimes have an amplifier in them. Sounds funny but they call the Radio in the dash the Head Unit and the amplifier is buried in the dash. You could have a bad amplifier or a loose power connection to it, but that is very unlikely.

Hope this helps.

Check the aerial connection at the back of the unit. Also check the wiring to the antenna, look for an intermittent connection.

If you do not find anything wrong then the problem is on internal wirings connecting to the antenna socket, if that is the case the radio must be taken apart and tested by a technician.

There is an amplifier located under the passenger side rear trim panel in the cargo area, the radio is just what they call a head unit, the amplifier provides the sound, that is most likely your problem.

The arial is internal, it is a wire, I think it is running on top of the driver door, not sure.

Check the aerial connection at the back of the unit. Also check the wiring to the antenna, look for an intermittent connection.

On many A4 there is also an antenna amplifier, if that is wrong it can also give you troubles.

If you do not find anything wrong then the problem is on internal wiring connecting to the antenna socket, if that is the case the radio must be taken apart and tested by a technician.
