Does anyone know how much power a car radio signal booster uses? Ihad to have one fitted by Halfords with a new cd radio player.Since then i have problems with battery holding its charge, i had to jump start it yesterday. I dont use the car everyday but ive never had problems before booster was fitted. thanks.

They have probably conected it to a permanent live, it should be conected to the live coming from the head unit.
