Good morning! Got my brand new GZNW 15″ now and my brand new Hifonics Colossus XI Final Edition. Unfortunately, I have the feeling that the Colli just doesn’t bring enough steam … what could that be? Before I had installed a GZPA 1.2750SPL, and my old GZNW 15″ at 1Ohm. So 1900W RMS. Now the GZNW 15″ runs at 2x2Ohm with 2x955W RMS. So exactly the same performance. However, purely subjectively much less thrust comes than was the case before. W I don’t know. Since the GZPA is gone, even a Northstar NSB100FT has been added. So there’s no power shortage. Even if I turn the Colli all the way up, the voltage doesn’t drop below 12.7V. Somehow I’m at a loss. With the GZPA 1.2750SPL, I’ve brought my sun visors to the visible swinging and the rear view mirror has always turned all the way up. Now the sun globes are moving. No piece and the rear-view mirror only vibrates a little. However, the sub with the Colli seems to do more stroke than with the GZPA. (also subjective). That I have the Colli times bridge (but are then 0.5Ohm), won’t work, doesn’t it?? Does anyone have experience values? Does that hold out?? Thank you in advance, Daniel.
