Thanks. Because I'm a lunatic and am paranoid about the water resistance of the Kappa's, I picked up a pair of Polk MM652 marine rated speakers.

Amazon has a great return policy, so I figure I'll try them both and see which I like better. Hopefully the Polks - I'd rather not to have to mask off the grilles when I wash the bike.

 

Im using Polk MM652 with JL MX280\4 amp and a JL FIX86 in my fairing of my 15 RGS. Sounds great I had a BT355 sounded great with the bike off but the sound was lacking when the bike was running

 

I've heard real good things about those new Polks!
let us know what you think.

 

Can you elaborate on this? I see nothing but good things about the 355. I do know that HD changes the output based on run/stop so this makes sense. Did you go a different direction?

I will for sure.

 

Yes the radio has 2 different outputs. with the LL it sounded great when the bike wasnt running but once running it sounded really flat, I ended up taking the BT355 out and replaced it with a JL FIX86 calibrated it using the sound track supplied. Sounds so much better.

Thanks for the info. But, OUCH! $379 is a bit steep. I'll give the BT a try I think.

 

I'm thinking of doing a similar build on a friends '11 RG. Do the pre-Rushmore bikes use a line leveler? Is the wiring different for a HK head unit to the amp?

 

On a PreRushmore you'll use a Line Out Converter (LOC) instead of a Line Leveler.
PAC SNI 35 is what you want.
