Just moved to a 2018 RGS from a 2007 Road King so don't know shit about upgrading my audio on the bike except what I have read on this forum.

I have already added Infinity Kappas speakers and about to order a Cerwin Vega amp and BT355 line leveler as I think that will give me a good starting system and one I can actually hear clearly riding down the highway.

Now the simpleton questions, regarding the BT355 which option should pick, Im guess first one?
CHOOSE CONNECTION:
Front Speaker Connector
Street/Classic/Road In-Fairing Rear Speaker Connector (ex. Ultra and CVO)
Universal

Also, does anyone have a simple schematic showing how the amp, BT355 and HD head unit should be connected, I know this is basic stuff but I have no idea and want to make sure I have all the bits to hand BEFORE taking my bike apart.

Do I need to run the power cable to the battery or is there another power outlet I can tap into?

One last point, is it worth buying the 4 channel amp and running wires for bag speakers IF I decide to add them at a later date?

I have the same bike and i did that exact upgrade except i went with component speakers. Yes you should run the power and ground all the way down to the Battery. As for a schematic there isnt one but the connection is pretty simple. You disconnect your front speaker connections between the HU and speakers. use the side coming from the HU and connect those to the BT355. Then the RCA outputs of the BT355 you connect as short as possible set of RCA cables to the amp. Then run speaker wires from the amp thru the rubber grommets that house the stock speaker connecters to the new speakers. I bought the B54 and ran speaker wires to the back of the bike for future saddle bag speakers.

Sounds perfect and easy, which BT355 option do I need to select?
Im also in Tampa, well Port Richey actually.

The first one is for your front speakers, the second if you’re running rear speakers (assuming an additional BT355). If you’re riding an ultra or CVO, you’ll need the breakout harness if you want to retain functions of the head unit.

I ordered the BT355 for the front speakers for the Rushmore Bike. I believe that's how they categorize it on their website. I also purchased 6ft of RED and Black 8guage power cable from a local car stereo shop with some connectors and an inline fuse. All total i only spent about $20 for my own version of an AMP install kit. let me know when you are ready to do the install and i will ride to ur place and give you a hand. I've been in and out of my front fairing so much the last few weeks tweeking the amp that i can do it with my eyes closed. Send me a PM and we will hook up, and i will help you install your upgrade.

As others have said, order for the front, as there is a difference in the two connectors.

The other option is to call Biketronics, and order over the phone. I think if you mention the RoadGlide.org forum, you also get a discount but it has been a few years since I ordered mine, so that may have changed.

I had a Biketronic 4 speaker set up on my 2013 Ultra Limited. I removed the system after the bike was totaled. I called Biketronics, they pulled my purchase invoice and looked at what I had. We discussed what I wanted to do with my 2017 RGU. I can reuse the much of what I have and just need to order a few things. I believe the total is a little of 300 dollars and I'll be back to having a great sound system. Biketronics is great to work with and you do get a discount for being a member of RG.Org.
