No. Until just a few years ago, radios were always manufactured
with speakers in them.
because there's no where else to put it
I am pretty sure it is just the radio wiring harness. I am guessing your car has no radio, but they put the radio wiring harness in anyway. On our car, which was a two door, the wiring went to both doors. It was extremely easy to put in a radio and speakers. The speaker size requirement for our doors was just a generic size speaker.
you probably have a short in your wireing
OEM equipment modifies the audio from the radio, sends it to the speaker and converts it back to normal audio on the speaker frame ckt board. To put in an aftermarket radio, use two of the wires and connect up to your new speakers and radio to make use of OEM wire routing.
In a Chevy Cavalier, you put the brake fluid in the brake fluid reservoir located atop the master cylinder. You can find this under the hood, on the drivers side, near the back firewall on top.
When you are talking on the phone u either listen with your ear or you put it on speaker or you can call it loud speaker. it is the same person you are talking to but you can hear it in aloud voice and do not need to keep it near your cheek....
Did the old radio have any sound? Do you get a strange code on the radio display indicating that you are locked out? You might have to pull the radio back out and make sure that the speaker connection plug is plugged in securely.
put the parking brake on the first click. it wont engage the brake but will turn of the lights but if you have a stock radio it will start beeping at you as soon as you hit about 10mph
You take off the panel that covers the speaker. Then you pull out the speaker. Then you reach in and turn the socket of the bulb and it will come out. When you take them out I always put a mark on which side was facing me so it is easier to put it back in. It can be a pain but you should be able to do it.
There is no ground for any of the speakers in a car. You will find to wires that go to the speaker but NEVER have the speaker wires touch any body metal. If you tie any of the speaker wires to ground you will short out the amplifier in the radio. On Ford vehicles the radio outputs are what they call Bridged Tied Loads. The speaker wires are not referenced to ground or battery. If you wish to find out the phasing of the speaker just put a 9 volt battery across the speaker wires and the speaker cone will either advance or retrack. Do this to all the speakers and note what color wir was on the 9 volt battery terminal
under tha steering colum there is a metal bar and above it is a little silver box. remove both and unplug the wires from that box and those will attach to your wire harness for your new radio. just run them up through to where the new radio will go. the factory radio will stay and the new one will go where the tape deck is. just did all that to my 1990 silverado
whats number do i put in to unlock radio is it security code or radio code to unlock radio?
