L2Tinker Ilike the idea to put labels on the enclosure and to put an overview under the PCB.
Please verify polarity of the loudspeker cables. The topview drawing shows the minus in the middle and the plus on the outer terminals. You find this also printed on the PCB close to the terminal block. Therefore your label must be L L- R- R . Wrong polarity does not damage anything but you lose especially the low frequencies in the sound then.

L2Tinker Sorry,but the plus signs disapeared in my text. The label on the output terminal block must be: L_positive / L_negative / R_negative / R_positive
