AIYIMA DC12V-24V 2.1 Channel TPA3116 Bluetooth-Compatible Stereo Subwoofer Amplifier Board 2x50W+100W BT Audio Amplifiers Board with Sub

So simple to wire up. Built my own blue tooth system - sound quality is great. Slight hiss at lower volume but for workshop/gym use - perfect. Crackles if not earthed, but once fully wired in, faultless. More on order for ceiling mounted speakers. Cheap and simple way to BT the whole house.

I've been running this for a week or so. It produces a good (adjustable) sound (shows how good your speakers are or ain't), connects by bluetooth easily, and is excellent value for money. Will report back if it lasts (or not)...

Sounds great, but in a vehicle you'll need to feed this more than the 12-14V your batteries or alternator provide as you will get a clipped output for the sub. I bought a heavy duty DC-DC boost circuit set to 24V. At high volumes, when the Bluetooth is connected the blinking blue LED introduces a high frequency noise.

sound output is very good.

Like other reviewers said (I should have believed them...): This amp is very noisy. It has a sort of noise suppression system, where the sound cuts out completely at low (or no) input, probably to mask the hiss you get while it IS producing output. I tried different power supplies, including a bench power supply at different input voltages. No difference. Also annoying is that it powers up in Bluetooth mode, you have to manually switch it to LINE IN every time - if that is how you want to use it. And it gives an annoying bleep on power up, AND speaks "line in" on switching to the line input. I got this amp to replace an old, equally cheap (LEPY?) 12V amp which did not have a subwoofer out. The old amp is now back in place. It does NOT hiss. This one is rubbish.

Good value for money, great sounding amplifier.

This will make a perfectly usable 2.1 system. However, the controls are not as described. The low pass does not work as such and low frequencies will get to the main speakers. If you have main speakers that can produce good bass, then OK. If looking for a proper crossover from sub to mains, then this is no way that. Noise is low. Frequency response is good, but crossover is pants.

No distortion, very loud and well made

Très bien pour faire un enceinte bluetooth assez puissante ! Pour le moment aucun soucis m, seul bémol l'antenne de base bluetooth est vraiment bof

Qua geluid redelijk, vrij klein stereobeeld maar leuk in te stellen met sub en normale stereokanalen. Snelle bluetooth maar... Continu een sis op de achtergrond. Op verschillende voedingen, accupack en voltages geprobeerd. Bij een lager voltage wordt de sis minder maar is nog steeds aanwezig en gewoon hard. Niet zachtjes op de achtergrond maar echt aanwezig. Daarom helaas een complete afknapper

Muy recomendable, suena bien y es potente

Ich verstehe die schlechten Bewertungen nicht.. Ich gebe zu wenn man es mit billig Netzteilen benutzt rauscht es wirklich ordentlich aber das lässt sich mit einer einfachen vorschaltung entfernen.. mit Akkus hat man kaum Grundrauschen und es läuft echt super! Ich hab ein 500 Watt Subwoofer dran und der kleine AMP bewegt den schon ganz gut. Ich betreibe den AMP mit 28 Volt ohne Probleme und alles läuft wie es soll.
