Rockville RPA9 3000W Peak/800W RMS 2 Channel Power Amplifier, High Output, Durable Build, Versatile Inputs, for DJs and Pro Audio

Very powerful for an 18" sub, on one channel only. Silent as compared to other. I am impress with the output power, please ensure you have the right amount of input power to get the best output. With a weak input power example phone the amp will under-perform. Easy to connect and the weight indicates the transformer inside will provide good power.

Works great. Clean undistorted sound

Using this for a home theater / and cranking music setup. I have it output wired into Rockville SBG1158 Subs via some SpeakON wires and from there i used the binding posts on the Rockville subs on over to another set of subs. Sofar after seriously thrashing some music its working quite nicely and especially for the price! I'm using this setup in a roughly 20 x 20 room that has a tapered ceiling. Depending on the song this amp can really crank out the bass. I will probably buy another to use in another room but in a stereo full range scenario.

Good price, GREAT sound, works exactly like it should, comes with a QR to view the companies how to videos.

I really wanted to like this amp for my mobile DJ setup, but there is not much good I can say about it. The case, connectors and knobs seem to be of decent quality for the price point.Unfortunately, the specs are majorly inflated vs actual performance. I only discovered this after difficulty mounting in my rack due to the mounting holes not aligning well to standard spacing. (6 other devices all line up well in the same rack)I bought this amp specifically to drive a pair of Rockville 3-way 12" 8 ohm pa speakers that I normally only use as a backup to my normal main speakers. I had a more crowded gig than normal this weekend so I decided to add this amp and use my backups in addition to my primary speakers. In order to drive them marginally I had to crank the gain all the way. With pretty much no headroom left it was all this amp had to drive the speakers well below their normal output as compared to my powered mixer output which is only 400 Watt. Keep in mind I've never pushed them beyond about 70% of my mixers max. The sound quality was also not as crisp through the Rockville amp.After reading many positive reviews, I thought this unit may stand a chance, but it just doesn't measure up in the real world. At the price I knew it wouldn't keep up with my Peavy or Mackie amps which are only rated 1500w - 1/2 the Rockville's rating, but I really thought it could be suitable to drive a couple of 12" pa cabinets that preformed well with the 400 Watt mixer output.Maybe the positive reviews are from better success with 4 ohm speakers, but even if that's the case, the amps power ratings are still grossly overstated.I plan on switching to an unpowered mixer in the near future and adding additional amps to my rack. I was hopeful that this amp would be suitable for that task, but it clearly falls short. I would have to use 2 of these amps and settle for lesser sound quality to replace my current 400 Watt output.

The amp is very nice. My fans are quiet at my power level. In fact, my computer fans are louder; perhaps after running with more power and heat they will kick-in.Construction is very nice. I do not believe the power rating stated (peak or rms).... I believe it is less, but without testing it......nevertheless, this amp is terrific. Clean, great sound for the price and works very well with my OSD Audio Pre-1 mixer / preamp. My speakers are home-made. Running (2) 8" woofers (low freq woofer and a low-mid woofer), a Bema horn from France when they were available.... running with my JBL 2445J , which is a 2446 Compression Mid Driver (16 ohm), and running a bullet tweeter. Crossovers are home made using 12GA wire (yes, very big and will never burn out).Anyway, I have only been using this amp for a few days but no regrets. In the future I will probably order 2 more of these amps to allow for 5.1 system, but still allow me to run 1 amp for 2ch music. To me, running the 5.1 / 7.1 / 9x /11x system never sound the same for listening to simple music on 2 channels.Many of the new and former stereo's over the past 20 years with all their "sound effects" do not support adequate current to drive speakers. They put too much of the special effects garbage (like toilet bowl, bedroom, auditorium, etc.... sound effects which are useless to me) and they could have made a better amp section. I also love Mac amps but could not afford at this time - maybe later.In the mean time I am happy with it. I will update as time goes on.
