To get a descent sub working to low base you will need at least ab 400 watt amp. I use a car Class D sub amp through my miniDSP

Cheers

You still have to have an active sub, the sub output is not amplified

As Dnic said. You need power to move a sub. I have an customized aiyima and before it a splitter to divide the signal. Then a 1000 w inuke dsp and a diy jbl gto 12" and I'm very pleased with the sound. Whaferdale linton are my speakers.

A TPA325 is a lot more futureproof than all the other mini amps. Those were fun to play with until the TPA3255 arrived. For not much more money you can get a killer amp which does it all in the TPA3255. A moderate to high level the TPA3255 will wipe the floor with those low power chips because it will still maintain a low THD.

Im still waiting for Aiyima 04 to come but i just received Zk 502T(Tpa3116). I can say that it is very good sounding cheap little amp. I connected it to Philips MC50 6Ohm speakers and for me it sounds better than any other active PC speakers in range ~100USD i tried so far. No hiss, clear sound and plenty of power even with 12V2A power adapter.

So you mean that I can buy some Y RCA splitter and connect two outputs = my tpa3255 amp with 2.0 speakers + active subwoofer to second RCA
sth like that --> eSYNiC 2 X 1/1 X 2 L / R Stereo Audio Bi Directional Switcher With Mute Button Portable RCA Stereo Audio Switch Audio Splitter| | - AliExpress

I have a Logitech sub that is around 12 watt RMS and IT sounds great. No need for much power. Maybe 2 to 4 times the stereo channels. Off course og depends greatly of efficiensy og the bass driver

Cheers!
