My Ford Taurus SHO Mach in-door speakers had blown out after 6 years of use, so a trip to Car Toys here in Portland, Oregon and $121 later (installed) I have crisp, clean sound once again.
The reference I used was Tom’s Diner, the a cappella version. The syllables were crisp, the silence was silent. I played it from my iPod running line out through a rcadirect.com CD Jukebox replacement unit. The song was purchased from the Apple iTunes music store, compressed in AAC 128 bit.
At 140 watts, these speakers should be able to handle my meager needs and being affordable, have made rocking out to my iPod enjoyable once again.
