Ok, I want a quality HU, preferrably where you can choose between having green and amber buttons, but I have no brand loyalty. My only requirements are that it have three preouts and one auxiliary in. I love the alpine HU's, but they dont seem to have an aux input, and I want to be able to run my MP3 player through it. I like all the standard features, but being able to play MP3's or WMA's is kinda negligible, since I want to plug in my MP3 player anyways. Lets assume that price is not an issue, but I'd prefer under 500 MSRP (and if I can get this for less, cheaper is better.) You guys know best, any recommendations? Or perhaps a solution to the lack of an Aux Input in the Alpines? Thanks.
