Having a issue with remote voltage...Possibly?

[Mynameismcgyver 10+ year member]

Having a sparatic issues with my remote voltage. Out of nowhere, I am having an issue with the amps/xm unit shutting off randomly. Turn the H/U off and it works again.

Took out the DMM and found that Idle voltage is 12.4 and dips around 11.4 when the music is playing. Drove around for a few min and it did its thing again at which the voltage was around 5.5 and not sufficient to turn my amps on. I am running two amps, xm unit and SMALL low rpm fan on the remote circuit and have not had a problem for quite awhile...( I don't believe it is related to having too much stuff on the 12V remote) However....My H/U is over 3-4 years old Alpine 9827

Thinking it has gone through its life cycle? Going to check for wiring issues in the daylight as well but I highly doubt it.

Hopefully someone can shed some light!

Another clue: Sunday, I ran into an issue with the xm unit turning off out of nowhere BUT everything else was fine...Seems like a problem started there and has gotten worse. Sounds like a H/U voltage problem that can't be fixed???

could be two things.

to many things on ur remtoe wire....put a relay in.

poor voltage...go have ur charging system checked out

Going to put a relay in tomorrow. I have a 210A alt and second Kinetic battery...But also have a US amp pulling up to 300A //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Got the relay hooked up and working. However, I am getting 13.5V at the remote on the amp. Is this ok?

no problem

I have had to use relays in the past with my Alpine Head units because they couldn't provide enough juice to keep two amps and a crossover powered up.

13.5v is ok.

my relay's power source is conntected to my battery. so whatever my battery is putting out my amps are receiving for remote voltage.

i got an even bigger issue...... hooked up 3 amps and now the remote line is on always! disconnected everything ran a seperate line directly to 1 amp and the headunit i constantly putting out voltage on the remote line even when the head unit is off

you sure you have it connected to the remote line and not your contant 12v feed?

check your wiring..

lol trust me, i had 2 other pros there they tried everything.... one day it worked with 2 amps. just added more wire and put another amp on and then boom, remote wire always hot.... idk how the headunit got fukd but it did.

just run it to a new wire. Not that hard.
