Description


Kenwood brand icon

Authorized dealer

The eXcelon Reference Fit amplifiers may fool some, but those who know Kenwood understand the power behind the aluminum plating. These amplifiers have a small footprint allowing installation in even the tightest of locations. Kenwoods Dual Sigma Drive technology is an advanced negative feedback circuit that improves damping factor and increases accuracy and sound quality. For those who need a truly custom installation the top plate can be removed and replaced with a creation of your choice. For such a small size these amplifiers put out a huge amount of power, just don't let it go to waste.
