Question about DB Drive A460 Car Audio Amplifier
I have one db drive amp platinum series connected to two 10" sub db drive speed series when raising the volume the amp goes into protect light cuts out then comes back on what could be happening help please...
It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.
