Product Info


Lifetime warranty on all the parts in this package!

This package combined the huge power output of the BT2180 amplifier, the BT7P1/BT7P1RG front 7.1” speaker kit, and a matching set of bare Titan II 6.5" speakers for the newer HD "CVO" style lower 6.5" speaker pods or custom applications. 

The upper and lower speakers will be wired in parallel for this application, usually done for radios without a fader/rear output function.  Examples would be Street Glide and Road Glide owners that have added lowers or Road Glide owners that are adding another set of speakers into the fairing.

Easily twice the power output of any other combo available today.  All without ruining the classic good looks of your bike.  No fake chrome plastic grill parts or anything else to distract from the great Harley design.
