SOURCE: Over heating
Are you sure it is overheating? Maybe you have the wrong speaker load and it is reacting to that. Is the unit shutting off when it "over heats"? Are you bridging and how many speakers are you using in what configuration (series/parallel)? Since you have two "new" amps doing the same problem and neither fan is turning on then I think you have a hookup problem and not a fan problem. Since you say you are using a large gauge of power wire (I'll assume you have an adequate connection to the chassis/ground) then that leaves only the speaker loading. I think you need to fix this problem quick before it blows your amps though. Good luck.

Could be the power supply or output stage electrolytic capacitors.
Possibly breaking down/drying out inside.
SOURCE: Fan not working
Mine too! I took it to my dealer. They said they had to send it to Alpne to be reprogrammed. I'm getting it back on next week.

Yes sounds like your not getting enuff power from the battery could be your alternator you should have it tested. Also have you try'd a capacitor? I put one in my car and it stopped cutting out...
