I looked at an ARCXDI 600.4 amp and it is Dimensions:9.020“ (L) x 6.268” (W) x 2.162 (H)
Is that the one you're talking about?

I'm about positive it is just TOO DAM BIG. Unless you have proof with pictures of how it will fit my 2013 fairing.

Also what is that Kappa thing you're talking about? What is a Kappa?

 

Are your rear speakers infinity kappas?

 

Oops You're right. They are called Infinity kappa. My mistake.

 

Arc moto 600.4. Same as tye xdi in a smaller footprint design specifically to fit in a fairing. Hit up Alex @ baggeraudiolab.

 

OK. I looked at the specs for this one. 8.12" (L) x 5.43" (W) x 1.8" (H)
I think it's still TOO DAM BIG for my 2013 fairing.
Anyone put one of these in a 2013 and earlier Ultra?

 

Tons of room and still room for more. One of my previous setups.

 

What year is that bike? Does it have the stock HK radio like mine does? Mine just barely held the Soundstream amp. I had to push and squeeze hard for it to fit.

 

I'm thinking of getting the BK 4180. Who do you think has the best price?
I found them for $543.95 Are there better prices?

 

Your call bro. You asked the question. I answered the question attempting to be helpful. I do this stuff everyday. No reason to listen to me. I didn't suggest you add a wheel barrel of components to your bike. I only suggested a set of speakers that would be more compatible with your present system. You've got poor system performance because you have the wrong mix of components in the wrong places. Simply replacing the amp is NOT going to solve your performance issue. I'm going to to say this one more time and I'm done. The Titan II speakers are not good speakers for your fairing. They are better suited in the lowers or the pods. The infinity Kappas need to be ran in the fairing. Good luck bro.
