Other than a amp and speakers of my choice, what other components do i need to install a 4 ch amp on my 2014 street glide special ?

Thanks

 

Line levelers. Biketronics bt 355 and a flash to 4 speakers no amp.

 

How much does a flash usually run or is it a diy job, do i need 1 line leveler or 2 ?

 

The flash for the head unit to activate the rear channels depending on the dealer is free to $60 Plus.
If the system if set up and balanced properly you can run a 4 channel amp off of just the front channels.
I just did a system on my dad's bike only using only the front channels powering a 4 channel amp.
There is a video I posted in the video section of the system.

 

About $50 from last I heard. 1 LL if only front, 2 LL if front and rear. You can Y split one but if you want fade need 2.

 

My first incorrect flash was $35 and then went to a different dealer that flashed my bike for free twice, just asked for word of mouth and let people know about them.
