The only thing ive seen that would cause this problem would be
a:a dead short on the wire
b:speakers are connected wrong, ie: + to - or - to +
if neither of these is the issue check your speakers to be shure they are not blown and shorted on the inside.
if they are fine then try returning the unit its probably defective

How do I connect my technics SB-G920 speaker to my Kenwood VR-60RS Audio-Video Control Center

I believe both devices, the speakers and the Audio-Video control Center is all but the same as many other past devices sold before the one you have at home. The only difference is their connection fittings at the back of either the speaker (boxes) and the Kenwood. I have such system, a 7 channel Quad-stereo system connected to a Pioneer Radio receiver/Amplifier and the connection of speaker wires are critically important to be connected correctly or else... Booom! gone is either the speakers or the Amplifier. Whatever your machine is, we always call it an amplifier, even though you can connect the video cables from a DVD player, through the Amplifier RCA sockets and out to a TV or Projector.

Now, you must have really heavy duty cables specially designed for high definition or HDMI video playback quality (without picture loss). Once you've determined the right distance between the DVD and the Kenwood and the TV or projector, you purchase these special cables. There are RCA video cables that have a better shielding and are usually all three as one cable with three RCA connectors on each end. Yellow is Video and is usually a thicker cable, followed by red (right), white (left) connectors. Take your time and pay attention on the correct connection to avoid trouble later. If you want a better, clearer video, you can use the S-Video cable. This cable has fragile plugs and when connecting, if you force them without aligning the right pins, you'll damage the plug.

Now, connecting the speaker. For a loss free sound, good quality speaker cables are essential. Otherwise cheaper cables are OK but it does seem that the sound quality is sacrificed on high peak (louder sound) as a fraction of energy and heat is generated through thinner cables than thicker ones, like when vacuuming a carpet, you can feel the cable getting a degree of warmth because the motor is labouring to suck and blow out cleaned air.

Start with the speaker boxes. Speaker cables usually have one wire colored and the other plain and they are as an 8 shape (o-o). The one that has a colored line marked on the cable is the positive wire. Before you start, split the splice the ends at least half an inch and twist the strands. If you have a soldering iron, solder these strands to form a solid wire, easier to insert it in the connecting clamps. Now, insert the one with the colored line marked on the cable into the red connector and the one without the line in the black connector. repeat with other speaker boxes. Place the speaker boxes in their locations before you cut the other ends of these cables so you don't end up having them too long or too short. I have already said why. Too long and too thin, the cables lose energy and releases heat. Too short and you have to restart again by purchasing new cables. Joining a short cable because of a mistake is not recommended. So, you either measure the before you purchase the cables or buy excess and cut to size later.

Now, the connection to your Kenwood amplifier is to be done really carefully as there are quite an number of connectors at the rear of the device and you have to study carefully which is what and where is which. It takes a little patience and a pen and paper in have to work out what is where. Bear this in mind that usually for large output speaker boxes the Amplifier had bigger connector to fit thicker wires (cables) and rear or mid speakers (pairs) have smaller connectors for cables that are slightly smaller in thickness.

For the largest speakers you connect the left (F) cable into the left clip-ons (or snap-on, or rotating screw type connectors where you just undo the screw, insert the wire into the hole and the screw tight), paying attention to the polarities (watch the colored line marked on the cable. Then do the same with the right speaker box cable (wires), insert them where it says right or just 'R'. The same goes with other speaker boxes. Paying attention their polarities.

Once done, test it before you put the Kenwood back in the cabinet or platform. if everything works as it should, then put the device (Kenwood) back in its place and give it a final check. Cheers

I have a kenwood kdc bt43u and transferred it, with my amp and rear speakers, to an identical vehicle. It all works fine until i use bluetooth. sound only comes from the front factory fitted speakers

Not quite sure what you are saying here but I am going to take a stab. If I am filling in the gaps but are the rear speakers wireless? If this is the case then they are not paired with the speakers but with your receiver deck. You will need to pair the speakers as well before it will play through them.

I do not know how to wire nenwood kdc-422 to a 94 buick century?

You should have a wire harness pigtail that comes with your kenwood.
you can also purchase a harness adapter plug/pigtail at most audio auto stereo shops to fit your car make and model.
Be sure to save the packaging because the plastic bag has the color/codes for the harness. This harness is designed to plug right into the factory plug inside the dash just like the stock radios do.
All you need to do is splice the kenwood cables to the adapter plug pigtail you purchase for your car.
match up each wire as described here:

Need to know the wires to install a deck for 97

Red is power to from ignition to cd deck
Yellow is direct power from battery to cd deck to hold the memory.
Black is ground
Blue is only needed if you are hooking up an amplifier.
I always suggest buying a wire harness quick connect system for $5, then you won't have to cut origional car wiring. If by chance you are taking the original wire route, then go to to find which wires on the car are for what.

Kenwood deck reads protect and won't function

you have one of your speaker wires shorted out to the body of the car somewhere, or the speakers that you installed are bad. That is the only two reasons it will go into protect. Correct the problem, then reset the deck - it should work fine.
Kenwood builds this feature in to protect the outputs - so they dont burn up in the case of shorted speakers or wiring.
