I'm rocking a 14 Ultra Classic & considering upgrading spkrs & maybe amp. I don't want to have to cut anything & would like to use factory wiring. Suggestions?

 

Alpine spr 60's. I'm no expert in audio but they took 5mins each to install and sounded pretty good when I was going back and forth from amp to stock output while trying to troubleshoot a problem yesterday. They run about $120 shipped. I'm sure there are other and probably better and cheaper options for a no amp system, just my 2 cents.
