StetsomIR 800.4 Compact 2 Ohms Digital Multi Channel Amplifier 800 Watts RMS 4 Channels 2Ω Stable Full Range HD Sound Quality Car Stereo MD Crossover HPF LPF Bass Boost Front Rear Bridge Speakers

So, over the last 5 years or so, I’ve been trying to get good sound in my back yard patio that measures about 30x50 feet. I started with a 100 watt amp, can’t remember the brand, but it definitely wasn’t 100w rms. Wife kept complaining that it wasn’t loud enough. I had bought 4 polk atrium speakers and ran 2 in parallel per channel. I upgraded the amp with a boss audio marine amp with more power (supposedly). Didn’t sound all that great. Bought 4 more speakers and paired them in parallel through 4 channels. Each pair gave the amp 4 ohms, since each speaker is at 8 ohm. Didn’t sound that great either. Very distorted sound when cranked up. Probably wasn’t enough power for all 8 speakers. Each speaker is max 80 watts. Upgraded again with this Stetsom amp. Not gonna lie, I have never heard music sound so amazing. I did buy a polk 100 watt sub and is tied into the system. Probably would be missing low tones if it wasn’t there. I notice that cranking it to 100% volume makes the speakers scream, so I adjusted the gain nobs until it was a good level. The power supply is a 600w 12v industrial psu. Overall, highly satisfied. And best of all… wife was very impressed and no longer complains ;)

todo llegó en orden, vamos a ponerlo a funcionar a ver qué tal nos va, lo conectaré brigde a 4 ohms

My system is a small one but you'd never know unless I show you. I'm buying another one of these to power another set of midrange I'm about to install.

This amp has good quality sound. The build quality is good, it is a nice solid heavy amp. It looks nice and sounds really good. I was able to get 100 watts x4 @ 4 ohms out of it cleanly. It may be slightly over rated wattage wise, but not by much. The size is really nice, I was able to fit it under my seat with no problems.

This amp is a monster: 800 watts to 4 channels? That's a lot of power. Absolutely great amp with massive power, incredible value from amazon with fast shipping. A+

Haven’t installed and used yet. Will update after doing so. But the amp was delivered and box was damaged. After opening I realized the amp itself was damaged as well. A little disappointing to pay this much money for a damaged product. Poor quality control I’m my opinion.

There’s a lot of power packed into this amp! Made really well and has good connections. Super easy to install and it sounds great.
