Alpine CDA-9815 Car CD / MP3 Player

I bought this cd player a couple years ago. It has been through 4 vehicles, and now it is going in its 5th. I gave it to my dad when I joined the military, and boy was that a mistake and a half! After listening to a lot of different cd players trying to decide what to buy, I finally called my dad, to have him send it to me. Not many cd players have the features that this one has. It is simply the best! The fact that you can hook it up to stock speakers, and make them sound like high end aftermarkets is amazing. The sound quality is unbeatable! Alpine is not incorporating the bass engine pro into their decks, that I can find. Shame on them!
