## Questions & Answers

**Q: I am running two per side (2 channel stero) powered by a b52 us 6000 can I add one more per side? Tnxs**
A: Three 8 ohm speakers connected together in parallel results in a 2.6 ohm load....Most power amps do not like this low resistance....What does your Power Amp specification say regarding its minimum load impedance...Typically the minimum is 4 ohms.

**Q: Which Xti series crown amp is ideal to power 2 of these speakers**
A: I would do XTI4002, its a pretty good fit, but if you wanted to push, XTI6002

https://www.amazon.com/Crown-XTi4002-Two-channel-1200W-Amplifier/dp/B004ZGB2RK/ref=sr_1_2?m=A2UPVLUE7LUM25&s=merchant-items&ie=UTF8&qid=1530658440&sr=1-2&keywords=xti

**Q: Does this item come with a warranty?**
A: Adam,  we are a full line authorized dealer for JBL.  They include a 5 year warranty, and we include our 45 day return policy as well.  Please let us know if we can further assist you, thank you!

**Q: What kind of wires do you Need to get for the sub**
A: The PRX418S accepts a Speaker Cable with a Speakon Connector (not a 1/4" connector)....12 Gauge is nice, but for cables under 25 feet long the 14 Guage is  fine...It's a 2-Wire Cable.

Delivered on time, these are some Bad Ass Stage Subwoofers. Run them through a Crown 5000 Watt amp and the bass shakes the stage

### ⭐⭐⭐⭐⭐ Excellent for church
*by D***T on January 21, 2020*

We use this subwoofer for our church and we plan on purchasing another one. Powerful. Good purchase for the price.

### ⭐⭐⭐ Didn't affect the function but not supper happy with it
*by D***N on September 27, 2016*

Arrived with a dent on the grill. Didn't affect the function but not supper happy with it. I needed the sub so I didn't return it even though the seller offered that option. That would be a huge hassle considering it's size. Really happy with the performance of the sub though. You'll want a nice strong amp to run it.
