So I researched several posts on audio and decided on infinity kappas 62.11 and a RF Pbr 300x2 amp. Only problem is I can't find the specific install info from Ultranutz. I see the sticky on audio forum page but can't find info on my bike and setup. It sounds from other members that is an easy install. Any help appreciated. Thank you.

 

I'm sure the gurus will chime in, but here's the basics:
- run power and ground for the amp (ground at the battery)
- use high level input for the amp (this will take a little splicing - run wires currently going from the stock head unit to the speakers to the input side of the amp)
- run new speaker wire from the output of the amp to the speakers, 16 ga is fine
- will need adapter rings for the kappas
- follow the sticky to set your amp gains by ear. Most guys will go with amp in HP somewhere around 90 hz to start.


That should get you started, are you looking for anything specific?

 

What HU are you using? ?? Stock
aftermarket /make and model#

 

Thank you for info so far. I am running a stock HU with this setup. Roadie, run both sets of speaker wires to input side in amp?

 

If you are running high level inputs take wires off of the front speakers and go to the high level input on amp.

 

Pardon my ignorance but, what exactly do you mean by high level inputs?

 

High level inputs is simply another term for speaker level inputs. You will run your speaker wires that are presently hooked to your stock speakers to the input side of the amp. The opposite of "High Level" inputs are low level inputs which require RCA connections to the HU.

You don't have Low level connections on the stock HU. Low level inputs are generally associated with aftermarket HU's. Hence you will have to run High Level inputs to your amp.

 

Here are some pics after it's installed and wired.

This forum is great! Thanks for the help. Ready to rock!
