The Velocity Double Trouble 8 Channel Harley Street Glide 2 Amplifier Combo Has All of the Power and Flexibility You Need 

We designed the RZA1000.4 amplifiers to perform in pairs when installed in a Batwing fairing. With 2.2 kilowatts and 8 channels of output, you will have so much power on tap that you will be able to drive an insane scale sound system without having to put amplifiers in the bags or tour pack. This makes the installation much simpler and it also dramatically reduces the cost of your installation. Amplifiers made for your Harley Street Glide, Electra Glide and Ultra Limited means that this amplifier array fits your bike and that you will not have to cut things up or get out the pry bar and big hammer just to get your shiny new amplifiers in the bike. They simply fit! Velocity amplifiers are the nicest amplifiers out there, and they also absolutely cost less once you subtract the expense and time required (extra wiring, cutting, and parts needed) to make multiple inferior amplifiers do the same task. This makes the Velocity Double Trouble SG-2200.8 Harley amplifier package a much better value for your dollar. Better sounding, big power, easier installation, lower weight, and ultimately lower cost. Go big with your Harley Street Glide, Electra Glide or Ultra Limited sound system.
