well was drivin to the store and amp went into protect. turned off hu and turned it back on and it came back on again with green light indicator on bass control knob. but when i turned t up again the same thing happened. so i left it off for a few mins turned it back on and it was playng fine, left my moms to cme hme and i was playin my system. the bass doesnt seem to hit at all anymore its like 1 12 is playing only. but they are both working and only goes into protect when knob is all the way turned up and plays for a few secs. thought maybe the fuse was blown but i have 2 fuses 1 from main battery to 2nd battery and one frm 2nd battery to amp. so i would think if one of those were blown it wouldnt work, ? unless the fuse from main battery to 2nd battery is blown and my amp is running of of the 2nd battery which is not getting any juice from alt. if something was messed up on the amp i would think that the subs wouldnt play at all right? lmk what yall think. i havent had time to look at it its dark now. just want an idea maybe on what could be goin on.
