I lent my amp out to a friend to use for a bit & all of a sudden it no longer puts out any power any ideas?

The blue led on the top still lights up, so the amp is still getting power, & both fuses are still good.
It still sends power to the speakers but the output is nowhere near were it should be.

 

keep a friend and an amp... won't lend it out unless you are prepared to give it away. You would be surprised how often this comes up.

Now assuming it works correctly, the only explanation is improper hookup (or an internal fault due to the removal, install, removal, install but lets ignore that for now). So please verify power is fully available and the + and -connections are on clean tight (rust free) connection points. Next since your amp is bridgeable, are the speaker wires hooked up correctly? verify clean and tight connections at the amp and speakers
(if this is going to a DVC sub you also have to verify whether the sub is in series or parallel)

 

I recall another member bout a month back having a problem with amp working but not as "loud" as normal... The end result was a bad ground somewhere. GL

 

Connections were clean & correct, to a single coil woofer. The amp functioned perfect for 2 weeks, before it just seemed to run out of juice lol.

I've also noticed there's no way into the dam thing to check it's inside unless it's cut open.

Should I attempt to cut it open?
Is there anywhere I could send this thing to be looked @?
Should I part ways with this beautiful amp? (I really don't want too)

I would've really liked to get this amp up & functional again, so I can hook it up to my Hertz Hi-energy hcx 690 3way 6x9's in my Buick Park ave. The last time I had these speakers hooked up to this amp in my jeep people thought I had subs in it. :-) & then they would sh*t themselves when they looked in the back & only seen 2 6x9s.
