Question about Alpine MRD-M605 Car Audio Amplifier
If you need more info let me know b/c i am new to car audio. My amps blue screen turns on my sub works fine it was tested with a multimeter. All of my wires I think are fine ( I had 3 people look at them). The ground was moved 2 times b/c of people not thinking it was grounded. When there is music there is no sound from the sub at all. Please help!
Hello, First of all with these new Alpine amps everithing adjustable just about is digital, as well as the internal workings of the amp to a point. If you bought this amp new then check your warranty or take it back where you purchased it if you can. Check that your amp is getting an input signal from your head unit. Check your head unit sub output settings, something could have gotten turned off or down. On this paticular amp if there is a problem internaly it would let you know or go into protection mode. You say your sub has ben tested and is good, check again. Hook another speaker up to the amp. Unhook that speaker and try, you never know. Like I said, if the amp is'nt going into protect mode and the digital display is'nt telling you any types of faults then it has to be the input signal. Make sure you are getting a signal. That has to be your problem otherwise amp would be in protect mode. Let me know what you find.
