The Eclipse unit is better made for SQ, and the Planet Audio one is made for DVDs. I'm not sure if I should remove the Eclipse one and replace it with the Planet Audio one, or if I should run both of them. They're both Single DIN and I have a Double DIN dash module. I could put the Planet Audio one above the Eclipse one and just use the Eclipse one for music, Planet Audio for video.
If I were to do that though, how should the units go to the amps? I could use a splitter so that both the Planet Audio unit and the Eclipse unit go to the RCAs for the amps but that seems like it might cause problems with both units sending signal to the amps, and maybe getting feedback/noise all the time There would also be the problem of the two different pre-amp voltages and gains always being wrong on one unit.
Or I could use an RCA/3.5 mm headphone converter and wire the Planet Audio unit to the aux input on the Eclipse stereo. Then I'd control the volume and everything from the Eclipse stereo.
Or I could just use one of the units and sell the other one. Any suggestions?
