Its time to replace the Infinity CD player. I have only found 3 silver units that hopefully match the silver column in the crossfire. SONY cdxm6o $200, sony cdx m30 $170, Alpine cda 9886M $350. All 3 listed as 'Marine applications". Hoping for feed back on these units. Are there special harnesses & hardware needed to install? Will they work with the factory speakers? And do the units fit in the same space as the factory Infinity? I am "old school," I still use cds when not using the radio. Don't own an ipod & probably never will. Any suggestions on more power for the audio especially when the top is down.
