OK, after doing a little bit of research Im guess I can get everything I need to get her up and running in the $300-400 dollar range.

BT LL - Biketronics obviously
Amp install kit (Power, ground, fuse...) 4 gauge or 8? (Amazon or where ever)
Fairing speakers - 4 ohm - any recommendations?
- will I need adapters to mount these?
Amp - 4 channel 4 ohm. How many total watts should I be looking for? any recommendations?
- Im guessing I will need a mount for this as well. I see them at Biketronics. Any other recommendations on where to get this?

 

Egg, IMO the BT 477 known as the BT Titan II's are a very good durable speaker it will be a great improvement over stock speakers on the 15 SG. I do not disagree with Gan very often, but the efficiency of the 477 is 93,2 DB sensitivity which is not an in efficient rating! The cheapest way to improve the stereo on your wifes bike would be to get a decent amp like the Cerwin Vega B52, line levelers (BT355) another set of Titan II's for the fairing. Wire the Titan's in parallel off the B52, which will give them 125 watts rms each, which is plenty of power (B52 is rated at 250 rms at 2 ohm which is what the Titan's would be wired in parallel). This will be a great improvement over stock! I ran the BT 477 in my lowers for years and found them to be a very good speaker in that location. I ran them in parallel off the front end of a a Sound Stream PN.4 520D which was !30 watts @ 2ohms and could hear them at 70 mph! I am pretty sure BT will honor there life time warranty for 2nd owner which is also a plus.

 

Mike, Thanks for the feedback. What is you thoughts on spending a few extra bucks on the Cerwin Vega B54? Seems to me that the biggest advantage to going with a 4 channel vs a 2 channel is the ability to fade the two sets independently. Is that an accurate statement? I would also have to take the bike to the dealer to "unlock" this ability if I understand correctly. Correct?

Do the BT Titan IIs bolt directly into the fairing or will I need an adapter?

 

Get a 4 channel amp brother. B54 is light on power so I would move on. Whether u like it or not, Momma is going to want the fairing speakers replaced. A very safe and solid play for the fairing is the Polk MM652. Kappas are a budget play. Hertz Millie Pro are a good full range etc. Since ur on a tight budget just make sure the fairing speakers will fit with the HD Fairing Pods.

The problem with the B54 is that for some reason it only puts out 80 rms per channel @ 4ohms while the B52 puts out 200rms @ 4ohms and 250 rms @ 2ohms. Having gains for each set of speakers is a good thing especially when your running different types of speakers with different efficiency ratings, not as critical when running identical speakers in parallel! Another inexpensive amp with 140 rms @4 ohms is the Sound Stream 1000D, it fits in a 15 Bat Wing but it is a tight squeeze, there are numerous threads and pics of the install (some very recent) on here, I think it fits on the 15 SG stock amp tray, but not sure ( I've got an 07 SG )! As far as the type of flash you will need on the SG, not sure since I never had to go through that, since I'm running an aftermarket HU. I'm sure somebody will chip in with that info! Good luck, a lot of info to consume at one time! You can always spend more but for an inexpensive solid system, I think your on the right track!

 

And with that being said, the hertz milles will not fit the pods without touching the back side of the grills. Im not sure if the polks will fit without modifications but just about any speaker will fit inside the pod if you have a dremmel and some time to mod it.
T is right about the amp. First get a 4 channel amp. The b-54 is only 80wx4 @ 4 ohms. If you run the Kappas being at 2 ohms then that amp will be enough (150wx4 @2ohms) and should make the boss happy. As far as a flash goes on the HU, you wont need one unless you want fade control from fairing to lowers. On a 4 channel amp, just 2 channel in and incorporate the 4 channel out for both fairing/lowers.

 

I have both.

 

There is a vid on youtube about incorporating focals inside the fairing pods. Looked rather easy to do. Im sure the same mod can be done for almost any speaker.

 

He already has the BT Titans for the lowers which are 4 ohm thus the B54 is just not a good play.

Opps didn't read enough. T is right ......(as usual)......not enough amp for the titians.
