The media could not be loaded. For video context, my workplace sounds like a plane engine going on all the times and need hearing protection and most bluetooth speakers like jbl boomboxes get completely drowned out. This little amp driving with some 88db sensitivity speakers(which is quite low, sensitivity rating determines speaker loudness, wattage ratings dont matter) keeps up quite a bit as you can see in the video a 400 dollar jbl boombox would not even be audible in a video. Used the line out with a male 3.5mm aux to dual male rca connector to hooked it up to a Klipsch r-sw12 subwoofer. Works flawlessly.3 ohm performance -I connected two pairs of dayton b652 which are 6 ohms each wired in parallel which gives 3 ohms final impedance. If you have the bass up to half way while volume is 100%, the amp will overheat and start cutting off. If you use bass or treble adjustments you'll need to get your max volume down to 60% or lower, whatever it takes to keep the amp running slightly warm and not hot. You can push the amp harder if you have a dedicated cooling solution like some fans or surrounding heat sink. This is of course pushing the amp far beyond the manufacturer rated limits of 4 ohms. I would definitely not push 2 ohms on this amp, it'll just overheat before it can get loud or play long enough. At least the amplifier has good protection circuitry to cut off before severe damage happens. Yes I've tortured tested this amp to a large extent and it survived with flying colors.With 8 ohms, 6 ohms or 4 ohms speakers the amp doesnt struggle at all. Also the bluetooth connection is very stable, on my s20 phone it auto connects to aptX and it sounds massively better than my coworkers iphone 13. The iphone 13 maxed out was missing like 2 clicks of volume slider in comparison to the samsung and lacking severe detail in midrange and treble like several wet towels were thrown on my speakers. Sucks to not have aptx and Ldac which is why I havent jumped ship from android yet.Bluetooth range is quite nuts. Farther than my best bluetooth headphones/earbuds. I got up to around 40 meters before it had issues and it was still playing and connected through walls as well.

connected to Magnepan 1.6 speakers. with cd player line out you'd be nuts to raise the volume past 12 o clock. bluetooth connection (which seems to use lossless codec if available on your source) needs a bit more turn on the knob but still plenty of room to get it loud enough. i too like bass/treble with a tactile neutral, but can overlook the lack thereof because playing vinyl pretty much always needs a bit of bass anyway. (with phono preamp needed of course.) would be nice if it had left/right balance especially for a simple setup without other gear, but you can't be too fussy. does not seem to get hot much at all. i do wish they would stop putting these bright blue lights on the front of every piece of electronic gear nowadays. 3.5mm line out may be useful someday... now if this thing could transmit the rca input to another bluetooth device, that would be astounding. but alas, only seems to want to receive.
