JAIME B on Dec 14, 2014
which one of these is better for my boxes i got two boxes already built into my back seat of car and i dont want to redo it they are 1.60 each box ported in center?
Bryan Z on Jan 26, 2015
Best Answer: Hello Bryan,

We recommend the NVX NSW124V2 . Not only is it a superior driver , based off of the success of the V1, but its designed to work in a smaller enclosure than that of its predecessor as well.

I have the first version of the NVX nsw124, can I hook up both the v2 and the v1 together?
Nicholas S on May 20, 2015
Best Answer: Ideally any two sub woofers who share the same rms and same impedance can be wired together. They must both also be either single voice coil, or dual voice coil; using one single and one double will not work.

I usually never recommend using two different subs together, mainly because a used sub and a brand new sub sound completely different. But, it WILL woro

The specs on this sub say 1.25 cu ft sealed box. Sonic Electronix sells a 1.0 or 1.5 cu ft box. Which of the two would be best for this driver? Smaller & tighter or larger with or without poly fill? I'll be running 440 watts into it (@ 2 ohms from the NVX 900.5 amp).
David B on Nov 22, 2015
Best Answer: I would personally go with the 1.0 cu ft box and stuff it with poly fill to make the sub think it's in a larger enclosure.

ok now im just wondering is it possible to flip these around in box i got 2 boxes stacked behind front seats was gonna mount bottom ones in and top one out has this been done?
Bryan Z on Jan 28, 2015
Best Answer: Hello Bryan,

What you are describing is called 'Inverted Mount' , and has been done for years --> . In regards to these subs, yes they can be, but please do your homework so you set up the drivers properly. Moreover, the sub has a proper gasket on it already, but we suggest making sure to protect the woofer with a custom foam gasket of some kind.
