My amp can power (at 4 ohms) either:
1) 1 sub at 110W RMS/ 160W max (bridged)
2) 2 subs at 40W RMS/ 80W max
Would 2 subs @ 40W RMS provide more volume, or punch, than just 1 @ 110W RMS?
There'd physically be more air moving (I think), but they'd be getting less power each.
The sub itself is 150W RMS/ 300W max.
