I got my sound system installed at an audio shop. I got 2 type Rs, the alipne 9847 head unit, Type r componet speakers in the front doors, Type 6 coax in the back doors, a rockford 1000 watt amp for the subs and an eclipse amp for the speakers, not sure about the wattage but I would say 200-400 watts. I also got a Farad Capacitor installed. Every time I drive at night with my lights on, everytime the Bass hits hard the indash lights dim. I have power windows and even when they are all the way up and push up on the button they dim. So anything you do that usues the battery it dims. Do I need something else, like a new battery?
