Q: I am running two per side (2 channel stero) powered by a b52 us 6000 can I add one more per side? Tnxs

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

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?

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

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.

my experience with jbl products since the 70’s has been it is some of the best audio gear availablemy how times have changedin all fairness since the speaker essentially failed out of the box i can’t assess any other feature or performance metrichf output was accompanied by whistling/oscillation then after about two minutes all hf output ceased

Sounds great!

Not inexpensive but a fantastic sounding cabinet and lightweight for what it is. We use this for practice jams with the band, couldn't be happier with sound and quality. Just excellent.

Just get it

Absolute monsters of rock. For now I use them as music speakers mounted they sound amazing, but I got them to be rock band monitors. I guess they have a fan inside? but I havent cranked them yet. 10/10

Not Worth Money & Bluetooth doesn’t work

Alright speaker, not worth the money is to small. Also connecting to bluetooth is a pain, i still never figured out how too after a hour trying. The app is also trash. I don’t recommend.
