Cb feedback though external am/fm speakers

I drive a 18 wheeler and use a slip seat cb box to house a magnum s-9 cb and a JVC am/fm. I hook the am/fm to the truck speakers with speaker wires from the box. When all speakers of the truck are hook up I get feedback when I key up a speak with the cb. I find that i do not have any feed back when one side of the truck speaker is not connected, it does not matter which side.

Re: cb feedback though external am/fm speakers

Hi Big OX,

Terrible problem.  I know what your going though.  Route your AM/FM Antenna wire, and Speaker wires separate from the  CD Antenna cable and power supply wires. If you can,  twist the speaker wires.  If the Speaker wires are run along side the CB Antenna wire for a short distance, you will pickup feedback. If you much have the Antenna wire get near the speaker wires, have the antenna wire cross the speaker wire at a 90 degree angle. Try not to run the antenna wire in paralell with the speaker wires.   Good luck

How do install speakers behind rear seat 2004 saab 93 convertible

Install needs to be done from inside the trunk.If there are no mounting brackets or holes,then you may want to get a speaker box and set it in the trunk.You can cut holes with a jig saw but that can be easy to mess up.

Speaker wires should already be back there.If there are no wires then run some from the back of the radio under the door thresholds(they are easy to remove and replace just a few screws).Then run the wire between the back of the seat and the wall.This will hide the wires.

Again back to a speaker box.They make life easy and can be purchased cheap at any stereo shop,or made cheap and fast.The pre made version will have wire hook ups and will be the correct size for the speakers.

I have a jvc kdavx1 trying to hook up to a 2000 buick reagal need to know how the wires hook up

Please let me know if you have questions, and thanks for using FixYa.

2000 Buick Regal Car Stereo Install Diagram jvc kdavx1
Radio Constant 12V+ Wire: Orange yellow
Radio Ignition Switched 12V+ Wire: Yellow red
Radio Ground Wire: Black/White black
Radio Illumination Wire: Gray/Black orange/white
Left Front Speaker Wire (+): Tan white
Left Front Speaker Wire (-): Gray white/black
Right Front Speaker Wire (+): Light Green gray
Right Front Speaker Wire (-): Dark Green gray/black
Left Rear Speaker Wire (+): Brown green
Left Rear Speaker Wire (-): Yellow green/black
Right Rear Speaker Wire (+): Dark Blue purple
Right Rear Speaker Wire (-): Light Blue purple/black
parking brake: blue light green

For this last wire, access the back of the parking brake to find a switch with a blue wire. Peel some insulation from the wire and wrap the stripped end of a 3 foot piece of 16 or 18 gauge wire around the stripped section. Solder and wrap the connection with electrical tape, route the wire to the jvc, then strip and solder the other end to the pigtail of the head unit.

If you are also installing a camera seeing behind you when backing, you will need to run a wire to the back-up light on the driver side reverse light (light green) wire along with your video cable.

I have a used unit, need instructions on how to hook it up to a caddy 1995 factory am/fm radio

Are we talking a new deck/stereo or new speakers/subs?
A new deck will require a wiring harness (cheap at walmart or local auto place) and this will come with a set of directions and wiring diagram for your make/model vehicle.
Subs/Speakers can be wired into a stock AM/FM radio (though I have no idea why anyone would want to do this) fairly simply, The wiring diagram will be printed on one side of your stock radio letting you know where to attach the 12v constant, the remote wire, and the speaker wires.

I have a problem with my car speaker/tweeter

Sounds like you have the ground and live possibly the other way around from the head unit to the speakers. The reason for you hearing it from both the tweeter and the speaker is that the tweeter is connected in parallel to the speaker.
Swap the wiring and try it.

Remote wire location

Hi and welcome to FixYa,

On the JVC, the blue wire is intended for a motorized or power antenna and therefore would only work when the JVC KDG-821 is set to tuner (AM or FM) mode. The external amplifier trigger from the JVC unit is blue/white. This should connect to the trigger / remote terminal of the amplifier.

Good luck and thank you for using FixYa.

I just bought 2 JVC CS-DX30 12" car speakers. What kind of box am I supposed to get sealed? vented? ported?

You can put these in either a sealed or ported enclosure, not vented. Your box choice depends on what kind of bass you are looking for and the power of the amp you use to drive them.

A sealed box will give you more accurate bass reproduction but will require more power for a given volume. A ported box will be louder at the expense of sounding somewhat "boomy". You should really listen a pair of 12"s in each type of box before you make your decision. Some people don't like the sound of ported enclosures, others love it.

I'd recommend one of the enclosures here:

Voice coil has been blown open. Most likely alot of times what I do to test a speaker is connect it to a 9 volt battery. on and off and the speaker should bounce. If not speaker is blown. Plus this way you could save yourself lots of problems. If the speaker was shorted and not blown open. You would now possible have a blown amp and home stereo.
