Do I even need rear speakers?
I wouldn't go with c5's for the money...Look into the Hertz Energy ESK 165, i wouldn't do front coaxials with no rears tho becasue you want the sound stage to be at ear level which having rear fill helps with
I also don't like the JL Slash amps by today's standards, they're old
, the HD's are better and the XD's are almost as good, but I'd prolly go with the new Alpine PDX 5ch, the model # isnt released yet, to power the whole system, and run your front speakers active which upps SQ tremendously.to run active I'd go with this head unit that comes out next month, it has auto time alignment and EQ plus electronic crossovers built in to run active, I already ordered one for that 66 Chevelle, and have JL C3's in that car with no rears...http://www.pioneerelectronics.com/PU...vers/DEH-80PRS
and a 10w3v3-2 is a GREAT choice for what you described as your needs/wants
