DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 2x50W+100W

Got more than what i expected...sound quality exceeds many premium branded 2.1 system.....i used 2 nos 8" woofers connected in parallel with a 2.2ohm 5watt series load resistance. This yielded real deep bass. But I had to reduse base volume to 70% as base was too high. Got great mid and high response by using sony speakers and tweeters. My 24v 5amp. Supply couldn't support its full volume. I recomend to use 24v 10amp smps supply. On pausing music and increasing all knobs to max. there was no hiss or humm. One cannot make out if the system is on or off as their is no hiss or humm sound even at full volume. This is a great plate and makes.a.premium quality 2.1 music system.

Compact and nice distortion free sound, easy Bluetooth pairing. Make sure to use an good 24V/5A power supply

Unstable, damaged, 3rd class waste of money and time

Running with 2 Magnetz subwoofer 8inch and some f&D stereo speakers....making it 4+4 subwoofer ohms and 4+4 stereo ohms...the subwoofer output bass frequency is super good on low frequencies... bluetooth function is good i went to the other room to test it's coverage and it didn't disconnect at all... over-all you must go for this product if you're a true audiophile!!!!Best class-d amplifier out there has to be this!!!
