Rockville RPA9 3000W Peak / 800W RMS 2-Channel Power Amplifier, Rack Mountable - Perfect for Live Sound, Pro Audio, DJs

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.

So coming from a self proclaimed (and friends and family too) audio snob, I can honestly say the Rockville RPA9 is a pretty decent amp. I’ve had it running in my home setup for three days and can honestly say this amp has great sound. All in all I’m pretty happy with it. I’m a collector of fine vintage speakers such as Cerwin Vega, Advent, DCM, Infinity and JBL all from the 80s and 90s. I strongly prefer Crown A/B amplifiers but wanted to give the RPA9 a try. Here’s what I think:Pros:It’s an A/B amp which I prefer to Class D. Class D just sounds so empty and flat. Which is a good thing because you can EQ the sound to your liking. But I enjoy the full bodied warm sound of AB.There is zero noise. Meaning no hiss or hun coming from the speakers when idle or under loadFor an AB amp it’s very lightConnections are easy to get to and manipulateOperationally it’s quiet. The dual fans don’t bother meBoth channels seemingly have equal power output. One does not seem to have more output than the other. My ears are trained for this.XLR balanced inputs and outputs to connect more amps if you desire.Cons:The power supply and transformer are very small. This amp will not give you outdoor concert levels. I believe when this amp has its gain knobs all the way up you are truly using all of its power. There’s no extra headroom.The paint work on mine is full of flaws.The power cord is really small. I’m talking 14 gauge with no built in filter.All in all this isn’t a horrible amp and I do recommend it if you’re looking for an inexpensive amp for your vintage speakers. At its price point and what I’m using it for, I’ll be keeping it inside the rack happily. It will power my Cerwin Vega D2s without any problems.

To anyone that has an Polk Psw505 with a blown amp and wants to bring them to life again this review is for you. I have two psw505s with blown amps, after viewing my options was to either buy an oem amps (250 each ) or an external amp. I decided to go with the rockville RPA9 amp to keep the price down. This amp pushes one or two polk subs on the bridged mode. It’s working out for me, I have a sony receiver with sub out connection so the bass is very clear. Down side is that it does not go as low as with the oem amp. Still shakes the house but nothing like the original. Volume is pretty steady until you hear the sub speaker starts to making small popping noise. This speakers are rated at 300rms and 480 peak amps, I know that they are moving well but they will not hit the lows, so if you like the rattle and ground shacking from the original psw505 you will not get that, instead you will get as low as 30hz and clean bass, don’t get me wrong, they hit really good but I am not going to push them until they pop. For this price I just saved two psw505s from trashing them and also saved about $300 dollars. Very simple wiring just get the right banana receiver plugs and banana wires. I spent on amazon $260 dllrs with wires and connectors, you can always drill the box and splice the wires together (save more $$).

I bought my first stereo in 1972 when I was 16. Became an "audiophile" in my 50's and have bought and sold enough stereo equipment to buy a small house. I recently had to have my vintage Phase Linear 700b amp repaired (vintage gear needs maintenance). This amp and my McIntosh 2270 amp are the nicest sounding amps I have ever owned (for different reasons) I needed a quick back up for a few months until the 700b could be repaired. My vintage AR9's are 4 ohm speakers and require Lots of Power. The RPA9 actually sounds very nice! Being a rock drummer for over 40 years you know PA gear and some amps will handle 4 ohm loads very well. The super inexpensive amp is doing a great job plus it's also pushing (4) 12" woofers! My two other home audio amps are the price of a used car and this amp was about $150 so it is a great buy and does a really nice job. Here's my comparison: A 92' Corvette LT1 is 300 hp, A Dodge HellCat Challenger is 707 hp. BOTH are powerful but different. No need to diss this amp so much. It sounds very good, especially for the amazing price. Very happy as a back-up amp and will keep it for other stuff when the Phase Linear comes back from the shop. Lots of experience means everything people.

This amp works. Has the power I needed for my club PA system.
