guys just got the pioneer 7550 and had it installed, napansin ko, when i play mp3s, pag-eject ko ng cd, sobrang init nung cd as in nakakapaso, normal ba yun? also medyo umiinit din yung vol. control pero di naman sobra. just wanna know kung defective ba yung 7550 or may mali lang sa installation, para mabalik ko sa shop if ever. thanks.
