Hi guys, need some help over here.

I have the Alpine Media player iDA X303 + Imprint sound processor PXA-H100. Been using it for quite some time and lately my battery was completely flat until 0-1V if left for 1 week.

My checking using multimeter at the bat terminal with charged battery and new battery changed recently

full charge 12.6-12.8V
1 day left about 12.4V
2 day about 12.2 V

I have changed all new amplifier wires+fuse+fuse holder and CONFIRM no short circuit to the body. After thorough investigation, to my surprise the next day I noticed the PXA-H100 is warm even it's fully off (key was at OFF position). the sound processor+HU is fully functional with all those EQ+MX etc. It looks like the sound processor is continously ON even the HU+key is turn OFF.

Please help...

the remote wire installed properly mou ?

check the remote wire with ur multimeter with the ignition off

you mean the Ai-Net cable?

for remote wire from the HU to the amp yes it's ok. if I disconnect the sound processor leaving only the HU+amp no problem. Meaning that the remote wire to the amp is ok. I leave overnight amp got no heat/warm means that it's really turn off.

If connect the sound processor with those Ainet cable to the HU (complete connection) if I leave overnight the sound processor is warm. it's like it wont turn off and drain my battery about 25% per day . I'm not sure whether the sound processor or Ainet cable or HU is the problem. someone can test for me arr? I can send over my sound processor. Wanna make sure which one to replace
