Summary: The Stage2 624 is suitable as a direct upgrade for 6.5" positions in front/rear doors. It works efficiently on the head unit and does not require an amplifier for normal use;

• For the best soundscape: focus on the front with suitable speakers, and keep the rear fill light to fill the cabin.
• Professional installation and light door lining improve bass and reduce resonance.
