The three different connections for the BT line LL are from the radio side going into the LL
* CHOOSE CONNECTION:
Front Speaker Connector
Street/Classic/Road In-Fairing Rear Speaker Connector
Universal

I went with the universal one and just swapped out the BT135
I could have done the front speaker connection one but wasn't sure if the wires would have been long enough as I have it mounted under the plate by the activation wire that goes to the amp. There is a "A" stamped on it.

 

Good call. The wires on the Front Speaker Connection are not that long so you are limited to where LL can be mounted. Another six inches or so, I could have mounted one to the right BT speaker bracket like I did on the left side.

 

Bert, I was afraid of the wires on the front speaker connection one being to short (for the way I wanted to mount it), thanks for confirming my decision for going with the universal one.

 

If I get the urge I may splice more wire to the LL to relocate it.

 

I know this is a dead thread, but I just bought the line leveler, and have the same problem as KSGLIDEGUY (cut the ends off the RCA cable). I followed the link provided by BertK, it's the mfg site, no retail. I've Googled the part #, called a local Rockford Fosgate dealer, no luck. None available on eBay or Amazon. Anybody has a source for part #1560-56458-01?
thanks,
Rat

 

I'm wonder if it was replaced with this. Give a RF a call back and ask to make sure.

 

That's it! Thanks, Bertk. $15 plus $5 shipping, got it on the way. Thanks again for the help.

 

Cool, glad it worked out.

 

I have a 14 FLHXS with saddle bag speakers. Will I need two of the BT355?

Thanks.

 

If each pair of speakers are connected to there own channel then yes you will need a LL for each pair of speakers.
