TDA7294 + LM3886 Amp 5.1
Default TDA7294 + LM3886 Amp 5.1

Welcome

I wanted to make myself amp 5.1 based on TDA7294 in bridge on the subwoofer and 5xLM3886 on other channels but the creation of the PCB is too hard for me
or maybe someone from colleagues has such a project and can share the schematic and PCB?
of course buying from Ebay.com also does not come into play too expensive

Use a two channel amplifier for the two rear channels.
Use a two channel amp for the two front channels.
Use a two channel amplifier for the centre channel and the bass only channel. This last can use the same power if the centre channel and the bass speaker have the same impedance and the same sensitivity.

If the bass speaker has a low sensitivity, then it will need more voltage to sound as loud as the centre channel.

Three two channel amplifiers are easier to build than a 6channel amplifier and get right.

Where are the speakers?
All stacked together in one corner of the listening room?

No, they are spread around the listener.
Locate the amplifiers beside the speaker that each are driving, using short speaker cables and longer interconnects.
