Is there any differance in the antenna on a 24 volt car radio versus a 12 volt system

Hi there, Try this...
Radio 12V yellow + radio, white 20 pin plug, pin 19 Radio Ground (chassis, base audio); black/white (except base audio) - radio, white 20 pin plug, pin 20 Radio Ignition blue + radio, white 20 pin plug, pin 7 Radio Illumination lt. green (parking light); black (dimmer, without navigation) +,- radio, white 20 pin plug, pins 9, 8 Power Antenna black + radio, gray 3 pin plug, pin 1 Left Front Speaker (+/-) gray - pink +,- radio, white 20 pin plug, pins 2 - 3 Right Front Speaker (+/-) beige - violet +,- radio, white 20 pin plug, pins 11 - 12 Left Rear Speaker (+/-) white - red +,- radio, white 20 pin plug, pins 4 - 5 Right Rear Speaker (+/-) blue - yellow +,- radio, white 20 pin plug, pins 13 - 14 Aux. Audio Input Left (+/-) yellow - green +,- radio, white 32 pin plug, pins 31 - 15 or white 24 pin plug, pins 10 - 11 Aux. Audio Input Right (+/-) blue - green +,- radio, white 32 pin plug, pins 16 - 15 or white 24 pin plug, pins 12 - 11 RSE Video (+/-) green - (shield) (rear view camera video) +,- radio, white 24 pin plug, pins 16 - 15 Satellite Radio 12 Volts (built into radio on premium audio)
Good Luck

That depends on your power source and what type of antennae you're using. Can you tell us if your antennae is a mobile antennae or a home/base station antennae? What is your power source, a car battery or a 120 volt AC to 12 volt DC converter? More info is good.

OK, that radio use a straight or constant 12 volts a ignition 12 volts and grounds. now your radio ground might be connected to the park light wires of the car. that wire will should grounds ( - ) but when you turn on the park light it turns to 12 volts to illuminate the dashboard gear shift etc. if that is the case you're wondering where you will get grounds to collect the radio, well the antenna wire has ground, so plug and play, and the frame where the radio goes has metal, which is also grounds. disconnect the black wire from the radio and that wire you can test by turning the park lights on and you will get 12 volts

follow this steps and fix it. God bless you

blem: I get noise on my car audio system that disappears when I turn the car off.
Possible Cause
Suggested Solution Alternator or ignition noise is being picked up through the power connection. Install a 12-volt noise filter between the power tap and the power input on your car audio. Back to the Troubleshooting Index Problem: The sound distorts at high volume when I play the radio in my car audio system.
Possible Cause
Suggested Solution The radio wattage is too low to drive the speakers. Use a car amplifier to increase the radio's power. Replace the speakers with ones which match the radio's output. Back to the Troubleshooting Index Problem: My car radio only get one station.
Possible Cause
Suggested Solution There is a problem with the wiring. Check the antenna circuit and rewire if necessary. There is a problem with the antenna. Check the antenna and replace if necessary. There is a problem with the radio. If you received more than one station with your previous system and you have already checked the wiring and the antenna, either replace the radio or send it to a service center. Back to the Troubleshooting Index Problem: My car radio keep running hot and blowing fuses.
Possible Cause
Suggested Solution The wires to different speakers have been combined rather than run separately. Make sure that each of the speakers has 2 wires run to it. Combining speaker wires will cause this problem. Back to the Troubleshooting Index Problem: I lose my station memories in my car radio when I turn off the vehicle.
Possible Cause
Suggested Solution The tuner memory wire may not be connected properly. Connect the yellow wire to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts. This connection provides continuous power for the clock and tuner memory when the ignition is turned off. Back to the Troubleshooting Index Problem: The amplifier stays on for a few minutes, then shuts off, then comes back on, then shuts off again.
Possible Cause
Suggested Solution It is overheating due to power issues. Check your power ratings to be sure they match the amplifier's specifications. There is a problem with the amplifier. If the power ratings are correct, the amplifier needs to be sent to a service center. Back to the Troubleshooting Index Problem: When using two amplifiers, I lose the right channel on one amp.
Possible Cause
Suggested Solution There is a problem in the sound system or wiring. Try swapping amplifiers or bypassing that amp. If the problem persists on the right channel on both amps, check the wiring and sound system. There is a problem with the amplifier. Replace the amplifier that displays the problem or send it to a service center .

I don't think there is a in accessories. The 24 volt truck systems are Cranking and Lighting. Either way you have no risk at trying the lower 12 volt car electrical. The problem is when you reverse polarity.

pos to pos and neg to neg for 12 volt but if your system is 24 volt thats a different story it will be pos to neg.and pos to neg

The antenna wire, witch should be yellow. is not supposed to be hooked up to 12 volts. It is only meant to be used as an on censer . If that wire is the reason your speakers are not working then the stereo is defective. That wire should have 12 volts coming out of it when the stereo is on. And hooking it to 12 volts could have damaged your stereo. I would look at the wire diagram again before doing anything else.

So anyway if you are not using the power antenna wire cap it off and leave it alone. you do not need it. Check all of your connections again and follow the wire diagram.
Good luck.

the amp requires a 12 volt power constant, and a 12 volt "on" signal. you prolly have the 12 v "on" hooked up to the car stereo's antennae remote, meaning your amp gets power when the radio is on, cuase the radio is sending a signal to the amp (thinking that it is sending a signal to the antennae to raise)

you do have one of those collapsable antennas, right?

your radio has 2 blue wires. one of them provides a 12 volt turn on for a power antenna (when a cd is inserted that 12 volt turn on turns off, because when a cd is playing, the antenna doesn't need to be raised up). The other blue wire has a 12 volt turn whenever the radio or the cd is turned on--this is the blue wire that you need to connect to your amp remote line. ( pull out the radio and switch the blue wires)

First order of business is to check and see if the antenna is operating properly. If the wire in your harness is intended to power the antenna, connect 12 volts to this lead, and the antenna should go up (this needs to be done with the key in the ON or ACCY position). If the antenna does not go up, check the fusebox for a blown fuse. If the antenna does indeed go up, then you can scratch that off the list of possible problems and move on to the next step.

The Clarion should have a power input wire to keep the clock alive, and a power wire (normally of heavier guage) to actually power the radio. Make sure the radio operates when the key is in the ON or ACCY position. If the radio is operating, so far so good.

I'm kind of confused when you say there are two wires on the clarion... "power antenna turn-on" and "auto antenna". Are these both on the clarion? There should be a wire that constantly feeds the antenna with power (I would cal this one auto antenna). It should always be powered to 12 volts. The antenna should operate when the "antenna turn on" lead becomes 12 volts. Normally this ONLY happens when the clarion RADIO is on (ie: if you're listening to a CD, the antenna probably won't get activated).

After checking all this, if you're still having problems and if you haven't already done so, grab a DC volt meter and verify that the clarion power antenna turn on lead goes to 12 volts when you turn on the radio. If it does not, then there is an internal problem within the radio. If this lead IS going to 12 volts when it is supposed to and the antenna still isn't working, then my guess is that the antenna is malfunctioning.

Let me know what you find out... I'll keep looking at stuff from this end. Good luck.
