I have a 97 Z28 all factory radio and speakers.(monsoon)
In this 6 speaker setup, are any of the speakers sub woofers? passenger area maybe..they vibrate so i have unooked them a while back..Anyway i intend to replace the factory speakers with some good ones..and i dont want to have to change all the wiring and stuff. .comments, sugestions..? thanx

 

the only way you can use all of the 6 speakers is if you get an amp. an aftermarket radio only has a 4 channel output.

 

I have JL Evolution XR650 compontents in the front and XR650 midbass drivers in the rear. Top of the line speakers right there. you can hear every single frequency. If you arent willing to spend the money for them get pioneer TA 6 3/4s for the rear and JL VR components for the front.
