Q: What do you get when you smash a D4 and a D Series Monoblock amp together?

A: 5 channels of output packed into an unbelievably small chassis with enough power to run your entire audio system from mids and highs to the sub stage.

The D5.500’s robust feature set includes high-level inputs with summing which makes it possible to seamlessly integrate into many of today’s OEM audio systems without needing an external signal adaptor. It also features a double sided-conformal coated PCB, angle lock set screw terminals, HP/LP/BP crossover networks, and an input selection switch. To complete this package it comes with a remote gain control with a clipping indicator.
