So I've got an American bass xr-12d2, dual 2 ohm voice coil 1200w RMS and currently an nvx nda105 monoblock amp (1ohm stable, 2000w RMS) but it's huge so I've been looking at other smaller options.
I found the NVX xad21 which is a 2 channel amplifier, 1 ohm stable (1000w x2 RMS), bridgeable down to 4 or 2 ohms.
RMS Power Ouput @ 14.4V, 4 Ohm (Bridged),≤1% THO+ N 900W
RMS Power Ouput @ 14.4V, 2 Ohm (Bridged),≤1% THO+ N 1600W
With the xr-12d2 being 1200w RMS, I was wondering if it would be possible to get the xad21 and bridge the sub down to 2 ohms for 1600w... Or if it would work, I could do the non bridged 1000w x2 with each voice coil on a separate channel but I've read that isn't as good. So I was hoping I could bridge this amp to the 2 ohm load for 1600w.
I know that the dvc 2 ohm subs can be wired to 4 ohm load, or 1 ohm load. And I think that when you bridge the channels, it divides the ohm load in half? If that's correct, could I wire the xr-12d2 in series to a 4 ohm load, bridged across the two channels for a 2 ohm load at the amp?
Or would it be better to just use the monoblock I have already? I like the idea of being able to use the 2 channel bridged for a sub, or for 2 stereo channels if I decide to put speakers on it.
The xad21 is 1 ohm stable and bridgeable down to 2 ohms so this should be okay load wise, I'm just not sure how I would go about wiring the dvc 2 ohm to a bridged 2 ohm load.
Hopefully my math is correct, and I can wire the coils in series for 4 ohm load and then bridge it to the amp across the two channels for a final 2 ohm load.
Please correct me if I'm wrong. Thanks for the help.
