In many of today’s installs, wattage per square inch is a deciding factor on what amplifier gets the job. For the D4.125, DD’s engineers were able to take the existing D4.100a’s compact chassis, which is only 7” x 4” x 1.7”, and increase the total output by 20%. The D4.125 can cleanly produce 200 watts per channel for a staggering 800 watts of total power. Beyond its amazing power to size ratio this amp is packed with features not normally seen on amplifiers in this size and price category.

The D4.125 also has conformal coated internal components and sealed back switches making it perfect for motorcycle, boat, and powersport applications. As if this amp didn’t have enough going for it, DD also has a line of made for Harley Davidson brackets that allow the D4.125 to cleanly and securely mount into 2014 and up Harley Road Glides and Street Glides.
