2 ohm or 4 ohm ?

[tjones770]

I'm using a Dual XPR520 to power 2 2ohm woofers in separate ported tubes. my question is should I run one woofer to each channel or should I run them like this photo shows. The amp says it's a 2/1 channel amp and it's stable to 2ohm. Being that the subs are both 2ohm should I just run them one per channel or the bridged way an]d have the amp see just one 4ohm sub?View attachment 26554518

when you wire subs in series, like the photo shows, the impedance spike is added in series. you may be happier with "stereo" wiring of one sub per channel.
