The eXcelon Reference Fit 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.
