Decided to go with the Arc 600.4 and the MEX M70BT in my '11 Ultra after talking to Haze and Gannicus. I've seen threads about some guys needing an amp mounting plate, some don't seem to need one. Do I need one for my bike? I'd like to have everything I need gathered up so I can keep downtime to a minimum.

 

Nope. That amp fits the fairing like a glove, All you need is some industrial Velcro from Home Depot. Sits right on top of the radio.

 

Before your put on the Velcro just clean the top of the hu and the bottom of the amp with rubbing alcohol to assure good adhesion.

 

Nice! Thanks guys
