Sorry dude that is not a question its a plea for a supernatural reading, not enough info.
Do u have power ie does it light up at all
Are the speakers actually there or did the guy take them with him??
There are usually two lives in, one for the higher amperage permanently live and one control wire usually from ignition, check because both need to be live.
Is it one unit or is there a seperate amplifier, you need power to both.
And check that the earth is actually earthed
Basically u need a mate with a multimeter to see if its the power in or if the unit is useless.
Also see if u can dig up a manual online.
