The 40 amp fuse is too small. 1000 watts = 12 volts @ 83 AMPS. Bigger power wire my friend. If you want to sell, let me know.

protect mode usaully means that something has disrupted the power of feed lines to the subwoofer/speakers possibly fuse is blown in amp or amp is blown in which we hope not. see if you have a warrenty if blown and send back or bring it to where you purchased it from.

You can check Both Crutchfield's learning center on subwoofer wiring diagrams and www.the12volt.com with their wiring diagrams. The crutchfield setup will be more informative for this type of problem. Just go one of the + to one of the - on each sub then wire the other plus's together between the subs as well as the minuses like between the subs and use the open plus and minus that u didn't just bridge. Then there should be just 2 wires a plus and a minus to the amp. Then follow the amp bridge wiring which should be found right above the speaker terminals it will be left plus to right minus or the other way around

If the amp stays in protect mode all of the time, I would suspect a short in the speaker wiring or speaker(s) voice coil(s), or perhaps a faulty ground. If it plays for a short period of time and then goes into protect mode, it is most likely overheating. First check all of the wiring. Test your speakers on a known good amp and make sure there are no places in your wiring where the insulation may have been damaged, causing an intermittent problem.

Many owners have reported that this particular amp has a tendency to overheat. Also, when run in bridged mode, the speaker impedance needs to be at least 4 ohms. It will overheat if the impedance is below 4 ohms.

Hope this helps.
