    have you checked the fuse? Most have a fuse anymore, right above the wire-bundle-connector plug-in on the back of the stereo. also there's typically two power wires that run into car head-units/stereos. Red and yellow... one is constant power, specifically for the clock & memory; the other is for ignition side power so the radio will work when the car is on and shut off when the car is turned off.

Yes the yellow needs to be connected to 12v power but so does the red one....the red is for when you switch the key, (switched power)..if u want to test it then hook yellow and red together and hook to a reliable 12v source.....then properly connect the black to a good ground....if it does not power then the radio is bad....if it works then it just needs to be wired properly inside the vehicle......yellow is constant, red is switched, black is ground, blue is accessory switched, and the dual ones are for speakers...i hope this is helpful...

Will my b4 250.0 work with out hand held remote?


Absolutely. Any car amplifier needs only 12v constant power, Chassis ground, and a switched 12v source to power up. Your switched source is most commonly from the remote turn on lead that comes from your head unit.

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.

Why do my subs work when the radios on but when i play a cd the subs dont come on


Hello m_renner67,

Most likely the amp remote terminal was connected to the head unit power antenna lead rather than the amp turn-on lead.

If the head unit does not have a dedicated turn-on lead, you can wire the amp remote terminal to any switched 12V source.

Hope this helps.

My amp is working fine but turns off when i insert a CD


Hello pumpin_up_da,

The most likely cause for the problem you describe is that the remote turn-on lead to the amp is functional only when the head unit is operating in tuner mode. This could be caused by using a power antenna lead instead of a remote lead. Some head units have both, some only one or the other. Check the wire going to the amp remote terminal with a voltmeter. If it shows 12V when the radio is operated in tuner mode but 0V when you switch to CD, then check the wiring. If this is the cause, and your head unit has a dedicated amp turn-on lead, then connect it to the amp terminal. Most head units that have both power antenna and remote leads code them "Blue" and "Blue/White". If your head unit does not have an amp turn-on lead, you need to wire it to a 12V switched source, usually the "red" wire on most aftermarket receivers. You can then put a SPST toggle switch (available at Radio Shack or most auto parts stores) in line with the wire and turn it on and off as desired.

If the correct wire from your head unit is currently connected, then the receiver is defective and needs repair or replacement. Or, if everything else still functions normally, and really don't want to bother with repair or replacement, you can still use the 12V switched source as described above.

Hope this helps.

Amp turns on with the tuner setting and plays, when i switch to ubs mode the amp shuts off


Hello daweeksy115x,

You did not specify your install specifics, but the trouble is probably the head unit "remote turn-on" lead. Some head units will have both a power antenna and a remote lead. If you inadvertently wired the amp turn-on to the power antenna lead, it can cause the problem you described.

If you head unit does not have a dedicated remote lead, the best solution is to wire the amp turn-on terminal to a switched accessory 12V source.

Hope this helps.

Jvc car audio KD-PDR51installation problem


Your switched ignition lead is hooked to a constant voltage wire.
You need to find a source wire that is only given power with the key in the on position.
One wire (yellow) on radio goes to a power wire with +12V constant power (regardless of key position)
The other wire (RED) on radio will need to be attached to a Power wire whose supply is only +12V when the ignition is enabled.
Since you are using a wire harness, you just need to reverse the 2 wires as they currently are installed.

Hope this solves one problem anyway.

the wires being reversed on the harness also may not activate an internal relay allowing the steering wheel functions to operate.Switch the 2 power wires, and re-try.

If the steering wheel controls still fail to operate properly, your module may be defective.

Post your results.

Your radio should have a blue wire with white stripe on it - this is the 12v remote turn on lead. You didn't leave the amplifier model in your post, but most any aftermarket amplifier will have only 3 power connections. One is 12v constant (battery), one is 12v negative (chassis ground), and the third should be a 12v triggered lead (either from a head unit or from ignition). If you are having trouble with this, I would recommend checking with a local stereo shop as they can assist you.

Installing CDM-7836 into a Boat


Yes I can help, the blue/white wire isn't meant for that purpose. That wire is meant for an amplifier turn-on. the wire you want to use is the red that is the accessory lead. What I would recommend is finding a constant 12V to hook to the Yellow and hook the switch 12V to the red. This way your radio will retain memory. Or you can connect both the red and yellow to that switch and never turn the switch off. Simply use the on/off button on the radio. Good Luck I hope I could help.

The head unit should have two separate +12V connections: One that goes to a switched 12V power that is switched on/off via the ignition and one that is always energized at +12V. If the head unit's switched +12V lead is not connected, the unit will not turn on (except for when +12V is first applied to the "always on" lead, in which case it will immediately eject the CD). Please respond if this is not the issue. Hope this helps!
