ok to start off, my car is a Integra, so far i have
Front: diamond hex componets s600s
Rear: Jl tr600-cx
Power: kenwood kac-729s (600watt max 2 channel) <--- only temporary, saving for arc audio 4150
nothing is installed yet, im still waiting for some dynomatt or raammat, and wires, and sub.

Hears my question, my rear speakers.. should i sell them and get a mid range driver? i think diamond sells one, the size is 6x5.....
Is it better for me to just go with 2 ways in back???? any ideas would be great...

ps: any ideas where i could mount a hidden head unit??? i want to keep stock look!!!

thanx alot guys
