I would suspect you nay have a bad antenna cable. The blue antenna wire is to be hooked up to an existing power antenna, so when the radio is turned on, it powers up the power antenna. The amp remote wire is to turn on a remote amp.

96, ford mustang, after market radio installation help! where to plug the amp remote wire for amp


The blue wire is a triggering wire of a low amp power for Amps or a power antenna. If it draws too much power (gets hot), use a relay for more power directly off the battery.
e,g..2 amp radio output and if the amps need 1.5 amp each that's 3 amp. Need a a relay.

Antenna not working


You don't say what make, model and year the car is. So a generic answer first....Check the antenna connector on the back of the radio to see if it has vibrated somewhat . The center pin will disconnect first before the whole wire comes out of the radio.

I hav a 29ltd classic cobra cb radio i had it tweaked first did not notice a diference in transmission but reception is still normal then i installed a rxf 75 amp and my reception decreased and everyone...


Receive amps on a Linear's can cause this issue---the key question is what is the dead key wattage in the radio adjusted to?

You hook an amp up--jumper cable length between amp and radio is critical---the power output of radio is critical--put 4 watts into a 75 watt amp and it will be over driven-- The proper way here is with radio and amp hooked to a big dummy load adjust the radio wattage output so the radio keys up the amp and gives maximum forward swing on a watt meter. (in some cases as little as 1 watt output from radio)

Some people call this matching the radio to the amp---The antenna system then becomes involved--further adjustment of the radio with the antenna system connected will be needed (power output) for the amp to work well.

If just a 29 LTD lowest Swr should be on channel 20.

Note: also important to check the swr with the Amp on as if power is being reflected back at radio when amp is on more needs to be done.

Am fm reception bad


FM reception is weak



What to do


• Extend the power cord as much as possible. The FM antenna is in the power cord.


• Move the power cord to adjust the FM antenna

• If you still have problems with FM reception, you may need an external antenna.


* Call Bose®Customer Service to request one.


The external antenna on your radio is a coax (round) design It needs an adaptor and an antenna which are cheap.


Easy to make, radio shack "F" connector 90 degrees or straight, to 300 ohm wire connections. Attatch a 300 ohm flat ribbon antenna cable to those two screws and plug into radio and see how your reception is. You will need to position the antenna wires to get best reception. I have hid them in back of paintings and so on.


Cheapest solution next to putting an extension cord on radio power cord.

Improve reception


HI there,

Well Yes you can improve the reception, please follow the below steps -

Improve FM Radio Reception -
 
1. If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive.
 
2. If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.
 
3. If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.
 
4. If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.
 
5. Temporarily switch to monaural mode to improve a weak signal on an FM receiver.


Improve AM Reception -
 
1. Gradually rotate the radio 360 degrees. Leave it in the position where it sounds best.
 
2. Reverse the AC plug if it isn't polarized. (If you can flip the plug over, then it's non-polarized.)
 
3. Plug the radio into a different AC outlet.
 
4. Move the radio closer to a window.
 
5. Experiment to learn if appliances and powered products in your home are causing interference: computer monitor, television, electric blanket, light dimmer, fluorescent light, hair dryer, air conditioner, smoke detector. If possible, turn off the offending item. Otherwise, move the radio to another room.
 
6. Upgrade to an external antenna if your receiver, tuner or radio has a place to connect one.
 
7. Buy a passive AM antenna that doesn't need to be connected to a radio or receiver.

Good Luck!!

Thanks

Where does the rem wire plug into


It plugs into the power antenna cord on your radio if your radio does not have a dedicated remote cord. The remote switch is so that you amp can detect when your radio is on and turn on too, or is off when your radio is off so as not to drain the battery

No AM reception for car radio...do get FM reception.


I was having the same problem with a jvc kd hdr 30. I Installed it myself over a year ago and never wanted to deal with the issue. Finally, I decided to take a look at it today.
On my head unit, all wires were connected except one blue one with a tag that says "do not connect to power, for remote device or power antenna only." This unit is in a '97' MBZ E320 with no visible antenna; I think it is part of the windshield. In any case, between the wiring diagram in the manual and the harness that is part of my car, I was left with 2 blue wires to choose from, one with a white stripe and one with a gray stripe. After testing both for power or ground, I determined neither had power with key on or off. Both had high resistance ground when compared to the chassis ground. In other words, I measured between chassis and these wires. First, I took a wire and connected it to the chassis ground and connected the other end to the blue wire coming from the unit while tuned to a local am station. This simply killed all reception am or fm but did not harm the unit. Next, I connected the blue wire with gray stripe of the car harness to the blue wire of the unit and again this killed all reception. Then I connected the blue wire with white stripe of car harness to the blue wire of unit and presto magic I had great am reception.
I am guessing that this blue wire with white stripe must be part of the antenna itself or perhaps is a connection that increases antenna power. Maybe 'power antenna' on tag refers to an actual powered antenna (like as in amplified?) and not as in an antenna that rises up out of fender, as I believed.
This may not help the first person with the question, but maybe it will help someone out there who searches for these kinds of answers like I do from time to time.

Amp shuts off when switched from radio to cd


your amps rem wire is hooked to the power antenna wire on your head unit and so when you turn off the radio you would nolonger need an antenna so it powers down and would lower the antenna.Depending on the head unit you should have one output for the power antenna and one for the amp rem......If your head unit doesn't have the rem output you can wire it to the switched wire that powers your head unit but keep in mind the amp will stay on while you have the key in acc or run position even if your head unit is off.
hope this helps!

Wiring car amp up


the rem wire is for switched power from your head unit usually most after market stereos(head units) have an output for the rem wire.......if not use the power antenna wire from the back of the radio (usually blue or blue white) as for the input you need to use one or the other low or phono
Hope this helps..Good Luck!

Works fine through 4 chnl. amp on radio until you switch to cd then rear speakers turn off


You have the amp hooked to the "Antenna turn on" which is the blue wire.... you need to hook it to the "REM" output whis is Blue with a white stripe.
