I have the rockford factory setup, its ok, rough when pushed. I purchased Polk di6500 components for the front and rear doors, a polk 660 to drive them, 2 polk 10" subs (if my box every arrives) and a polk 880 to drive them.
My plan was to use an ipad2 for source, but im not sure, means lots of works, i could just go with a 7" tablet in the sat nav slot and it would all look factory, leave the headunit etc in place.
In either case, i would plan to leave the headunit to control volume etc from the steering wheel. Or should I just dump the headunit? get a istreamer and volume control?
