STX Audio STX2000.5D 2000-Watt 5-Channel Class D Amplifier, 130W RMS Per Channel and 400W RMS Sub Output, MOSFET Circuit Design, Adjustable LPF and HPF for Car Audio Systems

great little amp. needed a 4.1 for my old jeep Cherokee and for the price this thing cant be beat!. first one i got had a bad channel 2 output. easy return and replacement arrived the next day. solid unit. feels heavy so hopefully they used quality electronics in it. sticker on the amp itself says made in Vietnam. replaced a 4 channel alpine and its just a tad longer but not as wide.

Clean, loud and powerful. Love it.

I have not actually USED this amp but this much I will say ,IT WILL NOT FIT ON A BAGGER HARLEY UNLESS YOU GIVE UP BAG SPACE. ITS TO HEAVY AND LARGE FOR UNDER THE FAIRING.

Excellent amp for the price point and easy to install.

So close, STX. If this just had the subsonic filter that is on nearly every other amp they offer, this would be the perfect all in one amp. Power a full 4.1 system off one amp. It can be overcome with a bass processor, but an all in one would have been nice. That aside, it is a solid amp that provides more than enough power to mess your ears up and be annoying at stop lights. People complaining about cost, crack me up. 150.00 is chump change. The same thing at the peak of car audio in the 80s and 90s would have been 10x this much.

I was looking for a compact amplifier to power some speakers at small events. This little powerhouse, with its 2000 watts and five channels, exceeded all my expectations. While it was initially overkill for my simple needs, I've found countless other uses for it, including setting up an outdoor surround sound system. The build quality and performance are surprisingly impressive for such a small device. It reminds me of the old-school car amplifiers from my teenage years, but with a modern twist and significantly better sound quality.

Nice amp, but in this day you either need to provide extra quality or a better price when you are new in this space. Too many established brands offering the same amp for much less. I for one would pay the same for a Premium brand or less with an established entry level brand...... ....UPDATE*** Looks like they listened and responded, this is an amazing amp for such a low price($140). Well worth the price! This will be a massive improvement over a factory stereo and plenty of power to run a 12 inch sub or a couple of eights.

This amp is solid and well built. It has good connectors and seems to be of good quality. The instructions are a little vague on whether the single channel part of the amp is 1 ohm stable. Now for the measurements. Using an oscilloscope I measured the output just below clipping. It did 56 watts @ 4 ohms x4 and 365 watts @ 2 ohms x1. This is all with clean signal with no clipping.
