Dual XPA2100 2/1 Channel 300 Watt Amplifier Car Audio Amplifier Questions & Answers
Connected a Dual XPA2100 300
The remote wire DOES need to be connected to the head unit. You can see if thats the problem simply by touching the remote wire to the power wire. The unit should come on. The head unit should either have a remote lead, or a power antenna lead, and thats what you need to turn the amp on and off. BE SURE your ground is solid, and its usually best to take that to the battery as well to prevent unwanted engine noise. Hope this helps!
My protection light is on
Either there is a malfunction on the amplifier , or more likely there is a short on the speakers cabling. If the cables are shorted, or broken, not allowing a sufficient load, the amplifier will protect itself by tripping a fuse. After a while, or on restart, the fuse will rearm itself, only to be tripped again by the malfunction.
Amp want power off
Hello
If your Dual Car Amp refuese to switch ON check the following.
+12V wire is not connected or incorrect voltage.
REM wire is not connected or incorrect voltage.
Ground wire is not connected.
Fuse(s) are blown.
If the fuse blows repeatedly, check whether the +ve voltage wire touche the chasis of the vehicle. If it is OK, the fault is with the univt itself. That is, the output of the unit has a short. Check for any output IC failure. OK.
I have my amp hooked
Check all your cable work.
Power is connected tight?
Ground is attached tight - on both ends (my guess is it is the ground)
Remote cable?
Is the ground a proper ground?
