Question 1

How would I connect a passive subwoofer with two wires? Does this have instructions for this type of setup or does anyone know?

Accepted Answer

There are connections on the rear marked "SUB". There are two + (red) connectors and two - (black) connectors. The instructions say that if you only have 1 subwoofer speaker (common), then connect the two red connectors together and connect them to your subwoofer. Also, connect the two black connectors together and then connect them to the other side of you subwoofer. They recommend wire nuts to make the connections.

Question 2

Does this amp have a voice? i currently have a douk audio amp that screams at you in broken english… i want to replace it.

Accepted Answer

BOY do I feel your sentiment here. There are some great budget amps on Amazon but so many of them have some stupid try-hard asian or British voice that's LOUD AS HECK and completely ruins the experience. I have to say, I've bought so many amps on amazon, including brands like DROK, kinter, Dayton audio, and lepai, and this particular amplifier from kinter is SUCH a gem. Just a simple, iphone like notification tone plays when Bluetooth connects or disconnects,.and that's it!! No annoying voice, SUPERB sound quality, and a great price. I'm waiting SO eagerly for this amp to be back in stock! I can't find them ANYWHERE else!! I found some on a Chinese manufacturer to consumer website but when they arrived it turned out they were an older model without built in Bluetooth! Still works just as well with a good choice of Bluetooth receiver, but the Bluetooth version is just so amazing to have and use. I'm very picky with the speakers I build and this thing is just amazing. Sorry for the long answer, I like this amp too much, but the answer to your question is no, no annoying voice on this wonderful amp.

Question 3

Sound quality equal to the 2020A+ limited? I like the 2020 but it has no sub out

Accepted Answer

The TI 3118 Chipset is probably the closest thing you will find to the 2020 in Class D amplifiers.  The 2020 does have a very unique  sound quality that's difficult to replicate.

Question 4

Will this be enough power to run the passive subwoofer in home theater setting?

Accepted Answer

I have a passive subwoofer from a Samsung home theater system that this amplifier runs. So far I haven't had any issues.
