Look under the amp...there might be a diagram or sometimes it shows by the speaker terminals theirself....google it or in my experience its the two outside terminals....
The problem is that the driver circuit is also damaged. Try powering up the unit with the output transistors disconnected. Measure each pad and report the results here. You should see something like 0.6,B+,0.0 on each set of three. Some will be negative rather than + (-0.6,B-, 0.0).
when i was running my sub off bridge mode this kept happening to me. I ended up just running two subs and for some reason the fuse stopped blowing. i think there is something wrong with these amps.
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.
No internal fuses. Your mosfets are toast.
A thumbs up would be greatly appreciated if this answer is helpful to you.
Nice amplifier. However it is best suited for speakers and not for sub woofers.
Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2.
Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4.
Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load.
If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.

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
I'm not sure if Lucent has a special bridging procedure, but on most if
not all other amps, when you bridge you DON'T connect two terminals
together. What you do is instead of using the plus and minus
terminals on one channel to one speaker and the other +/- terminals to
the other speaker, you will instead use the plus (+) terminal from one
channel and the minus (-) terminal from the other channel to drive one
speaker and the remaining + and - terminals remain unconnected. Be sure
you use the + and - terminals that are marked for bridging.
Please note, that when you bridge that your speaker load DOUBLES to
EACH channel. In other words, what your amp saw as a 4 ohm
speaker going to one channel alone, it now sees as a 2 ohm speaker on
each channel when bridged. Be sure you know what you are doing
before you bridge and fry your amp. In my experience, if after
bridging your amp works fine for about a month and then fries then you
bridged wrong and ended up with the wrong speaker load on each of the
bridged channels. Be careful. Amps cost a lot to
repair. Good luck.
I too replaced my bottom LCD with an aftermarket part and blew the fuses. I followed L1Cupids's advice and fixed mine. You have to solder F1 & F2 fuses. The insructions from the internet say to bridge the fuse with a wire. Well, it is only a 1/16 of an inch...I found this to be impossible. I just bridged the fuse with the solder iteself.

If I were a guessing man, I'd guess that you had your amp hooked up in a bridged configuration. And also that you connected your two speakers in parallel (plus to plus and minus to minus). And if I were to further guess, I'd guess that you have a blown amp now because of what I mentioned above. Sounds like you need to spend some quality time with your favorite electronic repair shop. Good luck.
Sounds like you have overloaded your amp. When you bridge you MUST make sure that you still have the proper speaker load. One 4 ohm speaker on one channel is fine, but when you bridge that same 4 ohm speaker, it gives you a 2 ohm load on each of the two channels that are now bridged. If you made the mistake of wiring two 4 ohm speakers in parallel (plus to plus and minus to minus) then when you bridge you will be driving a one ohm load on each channel. This is very close to a dead short. Stop using your amp at once until you get your speaker load correct. This will damage your amp and it will cause you to have to go to a repair shop to fix it. DO NOT RUN YOUR AMP ANYMORE UNTIL YOU FIX THIS. Good luck.
