I had this amp installed and had excelent volume, but suddenly the music turned off ( not the amp, just the music ). I dont know what they did but after 10 minutes it worked but with a lower volume ( I have to turn the knob to 25 to get the same volume as before with 17 )
Is there something wrong with my new amp they didnt tell me?? I asked and they told me they only used two channels with 4 speakers at 2 ohms and the other two are free for the subwoofer.
This amp is supposed to be 75W X 4 BUT my older amp was 45W X 4 and sounded louder
What should I do? Did they sold me something useless ??
