You should wire it just like you would wire your amplifier. But you ll use a thinner cable like a 1.5mm2 one for feeding it. 12v constant power from battery, acc power and negative/ground. In case your LOC has signal sensing capability, you won't need acc power.
Then use the LOC's remote output(if there is one) to the amp remote input. That way you ll avoid pops and clicks during switching on and off.
