xetec vs. AS Twister vs. Bridge

Hi, help me a bit on the jumps, I can decide abolut nciht. To the selection stand: Xetec G1200 Audio System Twister F2 300 Steg k2.01 Two crunch basses, each 300W rms at 4 ohm are to be driven, I want to run them at 2 ohm. Later, maybe n new bass should be pure, but that stands ncoh in the stars, the crunch will remain ncoh for quite a while. From the performance all three end stages are quite the same. I have the Twister and the Xetec pr and I have to admit that I have not noticed any difference. Vll. is due to the bad basses, Vll. also on me the two 2 channels would run then then already at 1 ohm, the xetec would have the advantage possibly still to have reserve, if at some time I switch to 1ohm woofer. the after part: it fits because of the square form nciht in my gfk and I would have to change some things. So what would you take? I have ncihtmal nen favoriten
