I have a Magnadyne Carbine PLUS-4600 alarm installed in my Civic 2001. I recently installed a 3rd party head unit in the car and the alarm started to act really strange. The alarm will not disarm and the LED light indicates that it's active. I tried a different remote and it still won't disarm. The only thing I could do is either remove the battery to stop the chirp or remove the battery cable. I tried also the valet trick, which you set the ignition to on and then flip the valet switch to ON and wait for the chirp, which never came.
I tried putting the stock radio back in but it doesn't do anything, I was thinking it was possibly some anti-theft mechanism that was set up to the stereo and if it didn't find it, it would trigger the alarm.
Currently, I have the cables that plug into the main alarm unit unplugged, so I can drive the car without the alarm going on. One strange thing is that when I do plug the alarm back in, the chirp sound is not that loud, it's like a bit faint and doesn't sound normal.
Does anyone know what could be wrong with it? Is the alarm malfunctioned or do I need to readjust something, since I swapped out head units?

x 2 with Pitt try a DMM across the + and - connections for a voltage check or find the alarms ground and power wires to see if they are secure.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
