I have a reckless fairing with an Infinity Bluetooth unit connected go 6x9 speakers. I just purchased an ultra tour pak. How would I go about connecting the unit to the tour pak speakers? Will I need an amp?

 

I'm not sure what Infinity head unit you have but there almost all four speaker setups so you should have two open channels to connect the tour pack speakers to. So you don't "need" an amp but I believe you would be much happier with one, IMHO.

 

It's the INFPRV250 unit. 50w x 4 channels

 

The specs online say 17 watts x 4 channels RMS, the 50 is peak power. RMS is the number you use.
RMS power is continuous power that the amplifier is capable of outputting over long periods. Peak power is short-term power that an amplifier is capable of briefly outputting when faced with sudden, high-energy signals.

 

A stock Harley '10 -'13 radio has 22 watts RMS to give you an example of where your infinity power lays. I got these numbers from Iron Cross Audio.

 

Any suggestions for an adapter to connect the tourpak speaker wire to rca? (I think the speaker Jacks in the infinity unit are rca). Also could someone recommend an amp that could mount inside the fairing?

 

Gotta have an amp Buck. . .I'd go with the PBR300X2 or the NVX micro amp depending on what speakers you are running.
