What I am concerned about is whether or not the Honda stock "Premium Audio System" (130 watts) will be enough to power the Infinity Reference Speakers. Will I have to increase/decrease/or stay same on the volume control? Replacing the rear deck (6x9) and door speakers (6.5), but keeping the factory tweeters in the dash. Is this a case of simply removing old speakers and putting in the new ones? OR is there special wiring requirements or modifications? THANKS.
