I must say in my experience pioneer has always turned out poo, esp in the speaker and head unit dept.
Alpine are the kiddies for head units in my opinion, and the v12 series are good amps, Rocky fosgate are meaty, Kicker are sweet (esp L7 square subs
) there are loadsa different companies but it would be interesting to hear of other peoples experiences with them and what they bought and how its sounds etc...
"You gotta have tunes" as my brother says
