I am looking at the following three headunits and would like to see what you guys recommend. If you have another option let me know about it. Time correction and sound quality are most important. The crossover abilities may come into play but my amps have that area covered. Thanks for your input. Alpine CDA 9887, Eclipse CD7100, Pioneer DEH-P880PRS. All of these do the basic features I need such as satellite radio and Ipod. I do not car anything about the area serve in the Eclipse. I am more concerned with which one would give me the best sound quality performance and have the best build quality.
