a yes im looking at the alpine cda-9887, im going to be running a passive crossover setup to my componet speakers, runing my head unit to a kicker 4 channel amp, then to the crossovers to each set of componets, then to the speakers, now my question is, is how would i go about tuning my system, will i be able to use the headunit to control the eqs of the stereo, or will i have to use the amp to set the eqs? ill also have a mono sub amp to my subs, thanks
