## 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

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.
