The Amplified Amplifier is a treasure on Pikmin 2. It is in the final floor (7) of the Shower Room. Getting it requires fast thinking as you need to defeat a Ranging Bloyster to get it. After you bring it to the Research Pod, it'll use it to create the Mega Tweeter from its innovative qualities, increasing the range of your whistle. The Amplified Amplifier is actually a 'woofer' on a stereo.
Being in the Explorer's Friend Series, it is part of the Exploration Kit.
