I have all my wired connected correctly and all of them work. my amp powers up but doesn't make any sound. have tried the wires on a testlight and all of them work. please help
SOURCE: alpine cde-9843 . i hand it in and working for 3 days then no sound.
Try a CD lens cleaner[A disk with a little brush and a bottle of fluid. But be prepared for a new player - once the lasers goes its trash can time.
SOURCE: CDE-9845 is not turning on or doing anything.
The only way to know for sure is to see if it has voltage getting to it. You need a Voltage tester (DMM, testlight, etc...). There should be 12 volts on the yellow always and on the red wire when the Ignition/Accessory is on. If both are present then the radio probably got surged and will have to be replaced/repaired.

probably the mode you are in, there is a mode for auxillary amplifier that disables the internal pa, in the aux amp mode you won't hear anything.

About Power supply wires (MRP-M1000 only)
• 21mm2 is the minimum power and ground cable size
that should be used to connect this amplifier. The
length of these cables should not exceed 1m to assure
safe operation.
• If the length of the power and ground cables exceed
1m, or if you connect more than one amplifier, a distribution
block should be used with 33mm2 or 53mm2
power and ground cables depending on the length
necessary. Ensure that you install a correctly-rated
in-line fuse on the power cable near the battery positive
post.
