HI,
Disconnect the speakers fist. then check the amplifier light flashing or not. If not then then any of the speaker is faulty. If the amplifier's Light flashing even after removing the speakers then any one of the amplifier stage inside the amp is faulty. By blinking it shows that its in protection mode.
Normally the out put transistor can become faulty. Which can lead to the amplifier to protection mode to avoid damages to the speakers connected to it.
If its not speakers then you should consult the Alpine service centre or any professional technician. Because repairing such type of amplifier should done by a very qualified person. If not it will lead major defects which will make the amplifier scrap.

Start with the headset powered on. Press and hold down
the call control button while also rotating the multi function dial
upward (away from the light) until the indicator light on the headset
starts flashing red then green. When prompted for passkey, enter
0000.
For the Plantronics M1000 (discontinued):
Hit and hold the volume/mute switch in until the indication light starts blinking.
For the Plantronics M1500 & A500 adapter
(discontinued): Turn the headset on and the adapter off. On the headset
push in and hold the mute/volume dial until the indicator light begins
to flash. On the adapter press and hold the blue power button for 10
seconds. The light on the adapter will flash once after 3 seconds-
continue to hold the power button for another-7 seconds until the
light flashes red. If the pairing is successful, the headset will
sound a tone and both the headset and adapter lights will turn off.
For both the Plantronics M1000/M1500 (discontinued):
If you remove the battery cover from the headset and then remove the
battery itself. On the Green PC board itself there will be a letter
followed by 4 numbers. These 4 numbers are your personal PIN code.

hope this helps.

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.
