I have a 12 CVO Road Glide (skunk) and i am looking to improve the audio a little. It has to the best of my knowledge the 5 x 7 fairing speakers. 2 inch tweeters and i think some type of factory amp.
What i am wanting to do is add fairing lowers with the 6.5 inches speaker boxes, similar to the street glide. Where i am at a loss is what type of speakers to add, brand is not the issue, rating is and how to connect them to the existing system.
I am not looking to go overboard as audio systems are an absolute mystery to me. whether something is 2 ohm, 4 ohm, etc just does not add up in my brain pan. I would like to use this as a learning opportunity.
so any advice would be appreciated. I do all my own work, so please be gentle and offer what would be solid advice. I really don't want to hear take it somewhere as that is not a learning experience for me.
i have reviewed a lot of posts on the forum and it appears polk, infinity or hertz speakers are popular speakers. However, i don't know whether they should be 2 or 4 ohm and, once purchased, how the heck do i hook them up to the existing sound system? parallel, series,

?
Appreciate any useful help. IF i need to purchase an additional amp, can someone please also let me know that as well. thanks
