Hello back,

The empeg unit will handle FM radio and mp3s. If you want a cd changer with the empeg deck you should/would get a FM modulated one.

1. The unit is powered by a wiring harness just like ant other deck that you choose to install. Other user have reported getting it to work with a tape adaptor and a cig. plug for power, but I don't think that is what empeg has in mind.

2. AFAIK it is one unit approx 7" wide X 6" deep x 2" (some one will correct me if I am wrong).

3. It has two pair (front/rear) of 4volt RCA jacks for output that are intended to go into an amp.

4. It should be VERY clear but that would depend on your mp3 quality, amp quality, speaker quality, and your definition of sound quality. Frequency seperation to speakers is the job for a crossover (or a good amp) be it in the speakers or and after market one.

This is as far as I can really explain with out re-reading empeg's website and going to my car-audio guru down at Mach1.

someone will probably come and correct me but oh well...
