Car stereo w/ power no sound

The new antenna is not properly grounded, or the power antenna is not a powered one. The radio uses it to ground, or the radio and light circuit needs alternate ground.

Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.

Is this a cd only deck, or does it have radio functions?

Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.

You have wired the amplifier turn-on wire to the power antenna wire by mistake.
The amplifier is turning off because it is losing the 12V signal in the power antenna wire when you go off the TUNER to CD.

Swap the blue wires, and you'll be set.

my brother has a 1993 Honda accord and had the same issue, we put it different speakers and it worked fine, don't know what the problem was but it worked

try taking antenna lead out of set and put a length of wire into the center hole were the antenna fits then scan,you should pick up at least one station,if you do fit a new antenna,if not try switching off any traffic anouncement services on the set ie press and hold button marked either ta/rds/tta/ast

Hi, I'm not sure I understand your question. It sounds to me like you haev a 1989 GMC truck, and you've installed a JVC CD player in it. The CD player has a blue and white wire coming out of the back, and you would like to know where it goes and what it does. Is that right? If so, then the blue/white wire labeled "Remote" coming out of your CD player is intended to turn on an external amplifier or some other "remote device". If your truck has a power antenna installed, this would be the wire that tells your power antenna to extend and retract. Many stereos have two of these wires - one for the power antenna and one for an amplifier. If you don't have an amplifier or power antenna, you don't need to do anything with this wire, just leave it alone and make sure it doesn't touch any bare metal behind the radio. Hope this helps.

You are using an amplifier in this vehicle. There are two "Blue" wires on the back of the stereo. One, antenna, supplies power to the power antenna during radio mode only and the AMP trigger supplying power to the amplifier in every mode. You chose the antenna wire to power your amplifier.

hmm, this is an old post, do u still need help??
If u do lemme know and i'll give u a few tricks u can use.

sounds like a new aerial is needed, if noone has messed with the wiring...

get someone to turn on the radio while you listen near the aerial...

if it sounds like it is making an effort to work then it could be the nylon runner...

if it doesnt make a sound check the power & earth connections at both ends, behind the stereo & at the antenna.

some have 3 wires power,earth & switched.
some only a switched & earth.
