finaly received my amps and just wondering what is a general opinion on these here on forum. and also i do seem to have a problem with the amp. this is the actual description on how to wire it from the seller :

Signal input mode can be selected according to the following two needs:

Balanced input signal (differential): Signal + Signal -, GND (ground).

Unbalanced inputs (single-ended): - end and GND (ground) short circuit, the signal input from the + terminal.

so i tried both ways of connecting and it didn t work but one way it worked was to connect signal ground wire on - terminal and left or right channel signal on + terminal. which leaves the ground terminal empty and amplifier sounding wierd like it doesn t have enough power.
