Hi there, I bought a 2007 electra glide fairing w / harmon kardon radio . Which wires on the 23 pin harness do i use for power,ground, & speakers. I have a 99 Kawasaki Nomad 1500 that i installed...


If it is the basic radio then here are the wiring pins for it:

RT FT Speaker - Pin 18
RT FT Speaker + Pin 1
LFT FT Speaker + Pin 16
LFT RR Speaker - Pin 17

Power and Neg pins are Battery Pin 10, Ground Pin 11

Ignition Pin 12

Another Power & Neg pins are Battery Pin 19, Battery Pin 20

These are the Pin Connectors for the stereo.

Wiring diagrams for clarion dxz535 car stereo


Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

There is a engine noise coming out from my speakers


(1) If you have an ohm meter check from neg terminal of battery to body of your car. It should be below 1 ohm. You should get the same reading between the amp neg terminal and the amp ground point. Check amp ground with the power off and the wire to the negative on the amp temporarily disconnected. Most cars have a braided uninsulated ground strap from the engine to the body or frame. In older cars this can break and it usually causes noise. Run a temp ground wire from the battery neg to the bat neg of your amp, if the noise goes away it's a ground issue for sure.
(2) Make sure the amp is well grounded ! The bolts that anchor the seats to the floor are one of the best ground points I know of.
(3) I've fixed a few amps that had an internal broken connection from the RCA's on the amp where they connect to the circuit board. This often happens from not having the amp bolted down and/or the RCA's getting hit or kicked. This will cause noise in the amp and requires taking the amp apart to fix it.

My amp suddenly stopped working. Orion-Cobalt 800.1 RCA Problems.


Hello icpdownie,

A grounded or shorted RCA cable could be the problem. Try replacing the RCA's.

Hope this helps.

My amp gets really hot as soon as the power comes on. what does that mean


Check your speaker output cable and connector, they might have connected to body of car.
  1. Remove all input / output cable from amp
  2. Plug the power into amp.
  3. if still the amp is still heating.
  4. Check if any screw used to fix is not connected any part of the amp output or input point.

AMP GUARD ON


I'd say go back to the guy who installed and get him to do it right. He's either left some wires exposed so they are intermittently touching, or has an open connection to one of the speakers. The amp will shut down to protect itself. He may also not have wired the speakers correctly. Some systems don't work unless both hot and ground wires run directly to each speaker. Some installers run only a hot line and use the car body for ground. At higher powers this can cause amp shutdown or keep it from working at all. In any case the installation wasn't done correctly.

Diamond Audio amplifier 1200W


If the speaker wires touched and the protection circuit didn't engage quickly enough, the output transistors may have failed. This is the most common cause for an amplifier to go into protect mode.

If you disconnect the speaker wires from the amp and the B+ and remote voltage are above ~11 volts (place black meter lead on ground terminal of the amp when checking the voltage), and the protect light still comes on, the amplifier will need to be repaired.
