i put in a pioneer p7800mp yesterday it sounds damn good i like it a lot, i cant live with out a mp3 deck in my car. i had TheFugitveMind start to dial in the eq setting i have the upgrade speakers there not bad for stock he was able to get the bass booms to come though on like hawthorne heights and the Used with out distortion. its crazy it has a 12 band eq in and even preset sound stages or cars, wagons, ect. the only thing i wish was different about it was its lighting colors but wat can you do, i can live with it. i also put in the din pocket to get a good clean oem look.
