the only other 2 ways to fix this is buy the cable and last find a rare schematic of this EQ. boxl.

here is the schematic.

The assumption is that it is a passive speaker with no crossover circuit. If you connect a good 9 volt battery to the speaker and neither hear or see a sound or movement the next step is to confirm with a multi-meter an open voice coil circuit.

It is possible to repair a broken wire but not likely a burnt- open voice coil.

Hope this helps?

I had two of these heaters and they both started to malfunction about the same time. The lights near the display window would not come on and there was a buzzing noise when it was plugged in. We determined that some kind of a relay inside was not working anymore. I got rid of both of these heaters and had to buy new ones. Seems like they lasted just past the warranty.

Hi there,

This usually means the voice coils have burnt out also.

When I was with Kenwood, it wasn't worth spending the time to repair units that had been overdriven (i.e. burnt out).

Either there is a short in the in the amp or hopefully just the speakers or wires going to the amp. disconnect any speaker input output and turn your amp back on(you will only have power, ground, and remote wires plugged in at this time) and if the red protect light goes away, then there is a problem with the input/output speaker wires, this includes your RCA's. If it's still flashing red then there may be a stray wire shorting to the amp in the speaker outs, other than that your amp may be fried. By the way, if it works without any speakers connected, including RCA's try connecting one component speaker at a time starting with your RCA's(if using them), speaker in, then speaker outs. If it turns into protect mode, note which speaker/RCA it was and replace or repair the short.

Just ignore the airplane mode prompt and if your wiring is correct everything should work.
With my BMW I had to connect both the solid blue (pwr ant) wire and the blue with white stripe (p conn) to the solid blue wire from the factory harness.

It isn't obvious that either of these are needed as the KVT-512 has it's own power supply but the way most factory power amps are installed the power from the KVT-512 is not used and the car manufacturers power amp needs to be turned on.

If you are listening to the radio the pwr ant wire will turn on the power amp, this didn't seem obvious because the BMW doesn't have a power antenna. And when you are using the DVD player or the iPod connection you need the P Conn wire to turn on the car power amp as the ant pwr is disabled because you are no longer using the radio and Kenwood assumes you will not need the antenna so no power to this lead.

Solder all three wires together and you should have sound all the time.

Okay there are 2 possible solutions depending on your problem

Number 1
If its the lead that plugs into the back of the headunit then this is the page you need Click Here All you have to do is choose the one you need! just look at how many pins there are pretty simple to work out

Number 2
If its the lead that plugs in from your car loom to the headunit loom then you need to look here and pick out your car

This will solve your problems :)

hi there
if you matched all the wires from the harness to the kenwood deck and its not working don't worry you just missed the last step........(all wires attached that a colour coded connected)
simply turn your car on.........now on the front of the kenwood deck there is a SOURCE button with all units it could be a (S, SRC, Power) hold the source button down till your kenwood unit powers up ..........if your unit still doesn't work check the fuse on back of kenwood unit should be a 10a fuse (blue) if the fuse is fine put the unit back in dash..........now check the fuse panel on driver side dash with the door open you will see this panel pull it off (some describe the fuse panel as looking like an air vent but its not its a handle to open) now on the panel that you just pulled off there is a fuse diagram on the inside look at it find radio fuse it will be a (blue fuse) located in the top row of fuses check it if blown replace and unit should work.............if this doesn't solve the issue than its a (sneaky) fuse not to many people know about if you pop the hood of your car there is a black plastic panel located just below the battery pins and just above the driver head light (usually black box with yellow writing on it......in this there are mini fuses check all of them do not touch the black relays in there just the small tiny fuses the fuse you will look at should be yellow 20a (this fuse is closest to engine and comes after the abs relay if you look inside the lid you took off it will have fuse locations cant remember which one it is for sure but check them..........now see if your kenwood unit powers up if not the last option is to ground to the black wire from back of kenwood unit to metal frame.............this last part is also done if your unit does power on but your car lights don't work if this happens ground the kenwood unit to the frame of car and open up fuse panel on driver side dash replace the blown fuse for lights or radio (make sure the kenwood unit is grounded to the frame before replacing the fuse in dash panel............if this doesnt help you than i would assume the kenwood deck needs to be repaired by kenwood.......
good luck
hope i was able to help and sorry this list is so long

The last Kenwood that I had witnessed with a flashing power light was defective. It also caused the subwoofers to move slowly back and forth. More than likely, you have an internal issue with the amp. Call Kenwood, and see how much they would charge to have you send the amp in for repair. Or pick up a new amp.

I work at Best Buy and I have one
