Ive buy this amplifier on ebay and its suposes to be 1400 watt in bridge mod 4ohm and 500 watt each channel at 4 ohm but i need to know if someone know if it could take 2ohm with more watt and safely .
Ive paid the amp 300 canadian $ with shiping fees.

Don't know anything about that amp, in general we recommend not using so called "DJ" amps.
One can probably assume the lack of a published 2 ohm spec means it's not supposed to be run that way.

What usually limits the ability of an amplifier to work with lower impedance loads is the current carrying capability of the components and wire.
For example with a 4 ohm load at 500 watts the current is just a bit over 11 amperes.
For a 2 ohm load at 500 watts gives a current of just under 16 amperes.
For a 2 ohm load at 800 watts the current will be 20 amperes.
So you can see that almost doubling the current would take substantially larger wiring and much more capable electrical parts.
