Help wiring an amp

[Ljungstrom235]

I recently bought a 500w kinter amp for my passive speakers and they came with red black and yellow power cables. How am I supposed to put those into a wall socket (UK)?

State the exact model - i suspect u must have bought one meant for use with cars/bikes and did not come with a PSU? if u wanted a compact, cheap amp the Lepai TA2020 is by far sonically the best
