Question about Xtant1.1i Series Mono Car Audio Amplifier
Alright so I've got a 121m xtant amplifier feeding a 10" sub. It worked until recently. I've checked the rca cables and connections, they're good. The red light is on and no orange or yellow lights are on. I checked the voltage on the power supply and continuity to ground, all good. The confusing part is that when I check the voltage across the speaker outputs I don't get anything on my multimeter (in the mV range). I do get a varying mV voltage across the postive (or negative) terminal with respect to ground...
Not sure what is wrong here, checked the jumpers and everything looks good...
You should be getting a reading from the speaker terminal if you have it wired properly & the stereo is playing.
if you are testing the DC voltage 'ACROSS' the terminals you will not get a reading.
Test the pos terminal as you did the main feed...Black probe on earth terminal, red on the pos speaker terminal.
If you are getting a reading then try a different sub.
continuity test across the terminals of the sub & push on the cone if the buzzer changes on/off as you push on the cone the voice coil may be burnt? pump the cone up & down it may clean it a bit?
