I have owned many power amps during my years as an active, gigging bassist. I have owned many sound systems and this is by far the finest power amp I have ever owned. I have owned my RMX 4050 for four years and use it to push a pair of 2-18 subs @ 4 ohms/channel. The band and I play small to medium rooms to 200-400 people and have been praised for our energy any the quality of mix. I feel that our tight low end is due mainly to the RMX 4050. It delivers all the low end punch we require and very rairly shows us an amber LED. At the price, I doubt that you'll find more bang-for-the-buck than you'll get with this power amp. Make sure your subs can handle the 1400 watts/channel @ 4 ohms because it will deliver all of this and then some. I recommend this power amp highly and know that you'll be happy with your purchase. I would buy another but have no need. My RMX 4050 has performed flawlessly for over 4 years and I expect that it'll last longer than I will.
Amazing...this amp really rocks i use in my two 18 inch subs and get the punch i ant for the music, if you intend to get this don't forget to buy speakers that can hold the power of this baby...qsc one of the best in mobile dj bussines
The qsc rmx 4050hd performs like none other. It is extremely efficient and the power it puts out is unbelievable. On top of that, it's a very quiet amp. I would use this amp only for high powered speakers or subwoofers. Do not plug in speakers not capable of handling at least 500 watts, because this amp is one powerful machine.
