Something has been mis-wired. Ensure the speakers are in the speaker slots and the power (Neg and Pos labeled as well) are properly connected. It is fairly common to get the speaker pos and neg mixed up with the power pos and neg. Hopefully, no permanent damage was done. The problem is between your factory radio and the aftermarket power amp.

You will have to take it to the Dealer. You may have burnt out or the "Control Module" needs to be replaced or reprogrammed. Make sure the battery has not reversed polarity also.

Red light on charger flashes. battery doesnt seem to charge.


If the red light is flashing rapidly it means that your charger has determined that your battery pack is in need of replacement and a safety circuit will not allow it to be charged. You may have an actual fault in the pack OR it may just mean that you have allowed the pack to discharge below the manufacturer's recommendations and the safety circuit has been fooled into thinking that the pack is defective. You need to decide which scenario is more likely correct. Using a DC voltmeter, determine if the battery pack has any voltage at all and which connections are positive and negative. If there is zero voltage, then you probably should go shopping and send your current battery to a recycler. If the battery pack does show some voltage, that is a good sign. TRY THIS AT YOUR OWN RISK! You can attempt to partially charge the battery pack (while not in the charger and not in the tool) by using test leads to connect it pos-to-pos and neg-to-neg to a fully charged battery of similar voltage/amperage. Only connect them together for a couple of minutes. Remove the leads and test with the DC voltmeter again to see if voltage in the questionable battery pack has increased by more than a volt or two. If so, it is still taking a charge. Move it back to its charger to see if there is now sufficient voltage to not trigger the safety circuit and allow it to charge normally. Wear eye protection. Don't cross leads. Don't try this on an obviously damaged battery or one that feels hot.

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.

sure, the red lead goes to the battery pos and the black lead goes to the battery neg as some cb radios have a reverse polarity idiot diode fitted, go with caution. With a multi meter you can find the neg terminal using the continuity or the low ohms
select on the meter...1 meter lead goes to the metal body of the set and the other lead goes to one of the power leads WITH THE SET TURNED OFF when the meter responds to a contact and shows low ohm reading you have found the neg lead..this lead is directly connected to the fram/case of the set. With a few sets
you need to have the mike connected in order to power up.
