Although i would really enjoy having an eclipse cd7100, it costs more than double than that of the cd3100, so does anyone have any personal experience with the cd310?
Another head unit that has interested me is the alpine 9883... so a better question to ask would be, what is better? The alpine 9883 or the eclipse 3100
but i think you should really get the cd5100 because it would be useless to get cd7100 since most amps can not output to 8volts, so i say stick to 5volts, and the cd500 has good features too
