that is correct or do it to a switch that you can flick on and off just incase a cop pulls you over then you can turn it off.
The reason for having a higher install price is they have the brain which is a sperate unit and then if it is professonal then they would run a new power wire to the power inverter. then they have to find a place to mount the ps2 securly and route all the wires nicely.
At my place PC Richards we install decks for 45 changers for 35 and power invertor for around 40.
