I went with Hertz components speakers. They've OK but not as nice has the high end Hertz I put in my Harley. If I were going to do it again I'd go with either JBL stage 3 components or Cerwin Vega XED650 as a budget choice. I didn't plan on adding an amp so I didn't want to drop a lot on speakers.
The cheaper Hertz components made an improvement though.
