2X 1000W sous 2 ohm, c'est possible avec cet ampli?

Hors sujet : Qui c'est qui a dit "T'aurais mieux fait d'achetter le PEtit Robert" ?

Citation : j'ai des hp RCF de 300wrms sous 4 ohm. j'en installe 2 par caisson soit 600wrms sous 2 ohm, bien sur, si je les mets en série, j'arrive à 600w rms sous 8ohm

Citation : "Well, I give it a thumbs up. The price - to - watt - to - performance ratio
is very good. Any questions, feel free to post a reply.

Stereo Testing:
This amplifier performs very well under 8 - 2 ohm configuration, when used
for Mid to High Frequency applications. Mismatched loads seem not to bother
the amplifier either. In Bass applications, this amplifier performs very
well under 8 - 4 ohm configurations. Occasional clipping is not audible to
the point of being noticeable. It clearly has a strong enough power supply
to withstand a clipped signal without oscillating.

Bridged Mono Testing:
This amplifier performs well under 4 ohm configuration considering its price
point. The one thing I should note is the audible distortion this amplifier
offers when not using its limiters located in the back of the amplifier (Dip
Switch 1, and, 10) when driven into clip. Although the amplifier heats up
rather quickly (2 ½ to 3 minutes) it doesn't shut down. However, the
amplifier starts to run out of gas the more you drive it into clip, and,
will begin to start distorting more, reducing its gain abruptly, and,
shutdown. Although it shuts down, it tries to reset itself very quickly
(Around 1 second). Providing, you use the amplifier with little to no
clipping , the amplifier performs well.

Short Circuit Testing:
This amplifier fully protects itself when it is driving a 4 ohm load,
bridged mono, elevated heating, and, accidentally encounters a shorted
speaker wire within the chain.

Heating Up, Cooling Down:
The amplifier heats up under low impedance, high SPL use in ruffly 3
minutes. This amplifier cools itself off completely in 2 minutes tops, with
no signal passing through, when driven at high SPL's, under low impedances.

The woofers conducted under the bass test were the Beyma 18 LX 60, and, JBL
2441. The impedance dip according to the cabinet design were 6 ohms on the
JBL, and, 7.4 on the Beyma. (Lowest impedance dip when used from 100 - 30Hz)

Note: Both woofers were used together when testing this amplifier to give
the worst case scenario of using multiple brand speakers under these
conditions.

The Music:
For the bass testing, the CD Maroon 5, was selected. Using tracks, Harder To
Breathe, and, This Love, which offers a strong emphasis on the kick drum.

Conclusion:
At a price point of $350.00, this amplifier performs very well, under the
given conditions. This amp would be perfect for a Band, or, DJ, that wants
power, but is on a budget. My compliments to Behringer for making a good
product, at an affordable price."

Citation : Désolé, ya pas de miracle, à ce niveau de prix, aucun ampli n'est réellement performant sous 2 ohms dans le grave. Leur alims sous-dimmensionnées ne peuvent fournir le courant nécéssaire à une telle utilisation...

Citation : Donc meme si on met le filtre 50hz de l'ampli ni le phonic max 860 ni le 2500 ne supporterai deux pro15 sur chaque canal ?
