So...I traded my 2011 Street Glide for a 2015 Ultra Limited. I swapped my first-gen audio upgrade back into the Street Glide for the trade (SS PN4.520, Pioneer TS-D1602s with adapters, Polk DXi-650s in the lowers and reinstalled the Iron Cross modified (pre-amps and BT) HK Radio), and removed the BT 4180 amp and BT7P1 speakers from the fairing and BT 477s from the lowers.

Can I get JUST the speaker adapters that replaces the factory pods? And secondary to that: has there been an update to the BT fairing adapters to include the spacer mod that I've seen here on the forums?

I also want clarification about the following info on the BT4180.14 page on the BT site: "Includes special amp mounting plate, enable connector, and the Biketronics Line Leveler pre-amp adapter for 2014+ EG fairing bikes. Not plug-n-play for 2014+ Ultra without additional wiring, please contact Biketronics for info." I have a BT4180 that came to me in January 2015 for my 2011 bike. Since I now have a 2015 Ultra Limited (with fairing and TP speakers) I know I will need at least 1 BT355 line leveler; but do I require 2 BT355 line levelers for this installation? Does the Limited need the Breakout Harness referenced on the Rushmore 4180 page? Do I NEED a speciam mounting plate? What is the "enable connector"?

Please advise, and thanks in advance!

 

it's 1 line leveler per set of speakers, so 4 speakers requires 2 LL's. I'm pretty certain you will need the breakout harness as well. I obviously can't speak for Bill/BT in regards to modification of the speaker brackets as they once existed, or if you can buy JUST the brackets, but I can tell you that with the mounting plate provided, you should have no trouble installing the BT4180 or the LL's. I just did this install a few weeks ago on my 15 SGS...plenty of room under the shell.
