I bought some new fairing speakers and they sound better than factory, but need more wattage. I have an amp already, but I'm not sure exactly what else I'll need to install it. Do I just wire it in to the speaker wires like my 12 was or are the news one more complex?

 

What speakers and what amp?

 

It's a Kenwood amp that was pulled from another bike when I added more speakers. I'm only running 2 speakers on this newer bike so it'll push them fine. The speakers are JL Audio. The amp was hooked up in the older bike just by splicing into the factory speaker wires. I was going to do it the same with the 14, but while looking around and seeing people talking about flashing and some kind of converter or something like that.

 

The BT355 line level converter will flatten the built in EQ curve the radio has in it as well as convert the speaker level inputs to RCA's. Those bt355s run about 80 bucks new. You can pick them up used in the for sale side many times for much less.

 

When the boom first came out, (2014) there were no one to re flash the head unit for aftermarket installs. The bt355 was the answer back then. Now most any aftermarket installers have the tools to flash a boom HU for the correct flash needed to run aftermarket components. In most cases you can find a local to flash for $50 or so and eliminate the need for the line leveler at a more effective setup with less $$ needed and no external filtering. I would suggest finding a local shop to flash your HU and be done with it.

 

True. I guess I was still looking at the fact that a flash for 50 bucks and then still needing a pac sni to convert speakers level inputs, would be as much as a single bt355. Since hes only running 2 speakers, its about the same either way. If ne needed two LL converters, then flash would be much cheaper.

 

I have never been a fan of the bt355 even though I have used them a bunch of times and have retuned each one of them. Just not a fan of double filtering the signal from the head unit thru the bt355 then thru the amp filter. In EVERY case I have used the bt355, it has needed tweaking as the default filter is set around 110 hz and most 6.5's will go to 85 or so. If left at default, the bt355 is leaving a lot on the table. Granted, at one time it was the go to interface between the boom hu and aftermarket audio but with some many out there that can flash a hu now, I try to stay away from them if I can.

 

So from what I'm reading I can use the amp I have now, but will definitely need to have it flashed by Harley or some dealer with the software or buy the biketronics converter. I had looked at this kit from them, but that seems pretty steep just for an install kit.

You do not need that for your street glide. Get your head unit flashed to either a RF flash or 8/2 flash. Then get this to convert the input to the amp. You will be set. Just make sure you get the polarity right when wiring the converter to the HU.

 

Ok thank you!!
