Hi, this appears to be just for 2.0 stereo sound & not 5.1 surround. I can't see how buying 3 units of "Black Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Car Amplifier 20W x 2+ Adaptor" will give me the surround sound.
I think the idea was to hook up all 6 channels to each. So front goes to one amp, the rear goes to another, and then the sub and centre goes into the third. Or you know any other configuration, like left front and rear goes to one amp, right front rear to another, then the centre and sub goes to the last one. You can change the volume on each amp so you can sort of "equalize" the surround setup a bit.There are 2-way speakers that has terminal connections to allow bi-amping; allowing separate amps for each driver. Works great because not only you can control the sub's volume relative to the woofer, having a separate amp powering the sub improves sound quality for both.
