Check your speaker, if it has damages or it is badly connected to the amplifier

SOURCE: My amp turns on then off while it slowly blows the fuse out

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.

SOURCE: AMp keeps blowing fuses

When any amp blows fuses, this indicates that something is drawing too much current. The most common cause are components in the output stage and driver stages that have become defective.

On the amp that is blowing the fuse with the volume being turned up, this means that the output stage is partially working. The short or over-draw of current must be in the output stage, or what is loading it. It is possible in this case that a crossover in a speaker unit is defective, and is drawing too much current. I have seen this with especially sub-woofer crossovers, and the driver itself. Subs pull a lot of current because of the amount of drive power required to have very strong bass sounds. Other than that, this still does not rule out the possibility of the problem being defective components in the amplifier.

SOURCE: fix for overheated Kustom KPM 7250 PA amp

You can start by trying a new fuse, use the correct fuse for your amp. If the fuse is blown, you can look at it and see the middle is burnt connecting the two sides.

I have two sp2 speakers i am using a ipod numark dj machine connected through my 2600 watt peavey amp it keeps blowing out one speaker can you tell me why

The SP2 speakers are rated at 1000 watts PROGRAM which is around 500 watts RMS MAXIMUM. You should be using an amp capable of a maximum of 500 watts a side... Your amp is WAY too big. You will have to throttle it down. The speakers have the protection for the tweeters but NOT for the woofers. At five hundred watts RMS and 8 ohms the current is: P = I^2 * R so I^2 = 500/8 = 62.5 so MAX current is 7.9 amps. I recommend you put a 8 amp FAST BLOW fuse in the speaker leads. If the fuse blows, you have saved another speaker and you are DRIVING them too hard. For greater safety make the fuse a 7.5 amp fast blow. Also get a sound meter. The max on these speakers is 125 Db at a meter distance... and in your venue you should NOT exceed 100 Db to be safe with the OSHA regulations regarding hearing protection... I suspect you are driving the speakers too hard. One side may be getting more bass. The speakers are rated down to 55 Hz. DO NOT boost bass up as you will overheat the speakers. If you are using microphones, be careful of feedback, especially that above hearing range. If you need real low bass, then get an 18 inch subwoofer. No matter, stay within safe sound levels to avoid lawsuits and hearing loss... I know several deaf musicians...

Kustom Profile One Blowing Fuses

likely a failure in the power supply or in the final power amp stage. Keep putting fuses in to "cook" out more parts to increase the repair expense... DON'T !!! Take for repair as a fuse isn't going to fix the problem.

I have installed a 12" w7 and jl 1000/1 v2 amp. I was useing the bass knob untill i found out on the jl website that its not needed for this set up. I was haveing problems blowing 80 amp fuses so i went...

It is NEVER a good idea to increase the values of fuses . Chances are you have internally damaged your amp. The next time you are faced with this problem you need to find out why your amp is blowing fuses and not keep changing the value of the fuse.
