I bought this amplifier from Amazon and despite no instructions regarding jumpers, speaker terminal orientation and polarity it does work. However, after few minutes uses the sound starts to distort.

We purchased several 10W DC7.5-15V 12v 2 ohm 20ma class D dual stereo amplifier. However, there were no wiring or connections instructions with it. Can we get a specification sheet for it somehow? Also, can we get any certifications so it can be used in EU products.
