Gem Sound clipping problem

I have a dj setup with Gem Sound amp EXA-3950 (3000 watts-1400 watts max peak per) with 2 Gem Sound TR-300's ( dual 15" woofers- one horn and 5 tweeters on each speaker --1000 watts peak?). we seem to have clipping problems quite frequently as we near 50% amp capacity--particularly in large gyms for school dances. the mixer we use is a Behringer 2 channel mixer with the gain about half way up. any assistance would be greatly appreciated. thanks!

First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.

What type of amp do I need for apair of rfdj1 12" dj 600w band speakers?

The 600 watt rating is FAKE like most of our advertising and will be either 600 watts PEAK or 600 watts PROGRAM. If it is Peak, use an amplifier with no more than 100 watts a side RMS... If it is program rating use an amp with no more than 150 watts a side RMS but that is pushing it for speaker safety. Also pay attention to the spec of the amp as to what it will output at the impedance of the speakers. I read the spec on the speakers... they are rated 150 watts RMS, NOT 600 watts... Use an amp rated at 150 watts RMS MAXIMUM at 4 ohms per side. Also don't turn up the bass excessively or you be buying new speakers. Twelve inch speakers would be adequate for a 20 by 20 room at SAFE listening levels. If you want driving bass, you need to get an 18 inch subwoofer.

You guys was helpful last time so I thought I would ask more!!!! DJ equipment Gem Sound amp EVA-3955 at 8ohms 2x250w blew 2 Tr-150 15'' 8ohms rated at 600w blew. what replacement should I go with same size...

Typically large speakers like that blow up because you are trying to put frequencies into them that they can not reproduce. How are these units connected? Is the crossover frequency correct for these 15" speakers? Putting signals higher than about 1000Hz will start to heat them up. too much heat = blow-up.

Also, I'm not familiar with the tr-150s. Is the 600W rating a PEAK rating or continuous?

I have Exa 3955 amp and TR-150 subs mid range and tweeter works subwoofers stop playing both

Open the sub box, and check to make sure the sub wires didn't become disconnected. You should need only a screwdriver.

Gem sound exa 3950 amp

Hi...
If it's a straight-up power switch then it will need to be replaced if it works off a relay then the relay is gone.

Speakers

400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power In other words the amplifier won't blow these out now.
