Hello. I just ordered a Alpine CDE-100 head unit. It has only 1 preout and 1 sub out. If I want to setup my stereo this way:

-headunit to amp to subwoofer
-rear speakers running of head unit
-front speakers running off head unit for now, possibly eventually being upgraded to it's own amp

Are all these setups possible with this head unit? Thanks.

 

looks fine for that application. you basically answered your own question!

Good buy, Alpine makes a solid HU. I never had any problems with mine...
