Personally I would stay away from Hogtunes, Boom and J&M kits, they are way overpriced for what you get, and sound quality. For an easy install I would recommend a Biketronics setup hands down over the others. They are a bit pricey but like what has been said, they have a lifetime warranty and excellent customer service. If you are willing to do a bit more work then you will need a Biketronics BT 355 Lineleveler that will balance out the crappy signal coming from the radio, an amp and speakers. The options for amps and speakers will depend on your budget and listening preference. The setup listed above with the Kappa's and CV B52 is a great budget option for 2 speakers. I have installed many of those with no complaints. If you have plans for a 4 speaker setup later on you will be money ahead to get a 4 channel amp with enough power now.
