Yes you can connect these wires to ground
this is used to prevent "Ground Loops" (un-even ground points in the system)
un-even ground points cause engine whine noise in the system and by connecting the stereo and amplifier grounds together usually resolves this issue..
So just connect one end to the same ground as the stereo and the other end to the amplifier ground location..

Hope this info helps

How to add an Exterior Speaker to Sony KV-13M10


Welcome to FixYa!

To add an exterior speaker to Sony KV-13M10, you have to have an AMPLIFIER.
  • At the back of your TV you will be able to see 3 RCA output namely = VHF/UHF, Audio and Video.
  • Use an RCA cable and connect to the Audio output.
  • At the back of your amplifier, connect the other end of the RCA cable to an RCA input labeled Audio - L (left, usually in white color).
  • Your speaker should be connected to your amplifier labeled output or audio out. The connection type depends on the make and model of your amplifier. The speaker wires usually come in red and black color. red goes to red, black goes to white.

A simple diagram will look like this:

TV audio out -------------> amplifier audio in (left, white color) amplifier audio out (left, white color) -----------> speaker (black wire) amplifier audio out (right, red color) ------------> speaker (red wire)

Thank you for using FixYa.
Have a great day.

How do you connect the back cables so the sound will come out right


There are four posts - two black and two red. They should be connected together, as shown in the picture. If you are missing the brass straps, simply use wire to reconnect the posts, black-black and red-red.

Then it's a simple matter of connecting the red (+) amplifier output to one of the red terminals, and the black (-) amplifier terminal to the black terminal on the KEF.

The KEF terminals can be seperated if you wish to "biamp" or "biwire" these speakers. Each black/red pair is dedicated to either the bass or the treble. For higher fidelity, some listeners prefer to run seperate wires from a single amplifier channel to each individual speaker input.clmrt5000_5.jpg

I have a brutus bxi 1206d 1200 watts, and the amp is coming on fine not protected. But there is no sound output. u can hear a small feedback rumble when connecting the input rca's. But thats it. My...


i would check the speaker cables to see if something came disconnected first maybe wire i touching other terminal shorted out the channels output .

run a new set of rca cable to see if one use are bad . check to see if rca cables pluged into right output of radio . check to see if your remote wire is powering up the amp to turn on the amp ..

will still light up with battery power but will never put output to the speakers with out the remote turn from the radio ... how to check this is to disconnect the cable at the amp and take a short 18 gauge wire and strip both ends and touch the battery terminal at the amp terminal one end the other end where the remote wire is mounted on the amp if do this for a few seconds to see what happens or better yet buy a digital volt meter and check for 12volt a the remote wire when you turn on your radio

With eng running, noise out of woofer and one tweeter. Even with eng. off some noise comes thru?


You need to reground your black ground cable, make sure that you strip the paint off the ground surface to the metal, then make sure you get a thick screw and a good ground loop and ground that screw in tight without stripping it, if the problem persist then buy yourself a noise filter at a best buy, car audio store and wire that in between your speakers and the connection cable.Check your battery's ground on the terminal, check to see if your radio is correctly installed, also keep in mind that if you have any cheap equipment like your radio or speakers cabling that could also cause engine noise.

Good luck.

I dont know how to setup my amplifier to MP3 Stereo...


Just like any other stereo. Get a wire harness for your car and match the wire colors together, tape them or cap them, or best yet soder them. Then run rca cables from the output in the back of the stereo to the amp. The run a remote wire (bue with white stripe) from the stereo to the amp remote terminal. Hook up the amp normal. let me know.

Where are the amps and how do i by pass them for the stereo


The amps are located inside the radio. Most in-dash receivers that provide for "pre-amp outputs" also called "low level outputs" do so by providing female RCA type jacks. These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible. To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals.

All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.

I hope this helps!

Need wiring instructions for vbx12a


You will need the following:
A power wire (preferably 4 or 8 gauge) with an inline fuse (typically 50amps)
A battery terminal adapter to connect the power wire
A signal wire to let the amp know when the stereo is on
RCA audio cables to connect the amplifier to your stereo
A ground wire for the amplifier (again 4 or 8 gauge preferred)

Walmart sells a Scosche kit that has all of the wiring as well as a basic diagram for about $25, but it does not include the battery terminal adapter.

If you have a factory stereo you won't have RCA ouputs, so you will need a line level converter. A basic one like the Scosche SLC4 usually runs in the $20 range. You splice into your speaker wires and run them into the unit, then plug the RCAs into it.

No power output


Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal. If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC. Let me know what you find.
