Right now, i have a Kenwood touchscreen powering all factory speakers and a Rockford Fosgate T1500-1bd powering two Rockford Fosgate T1 10" subs in ported box. I'm looking to upgrade the rest of the audio in my car, but since I had the Shaker500 originally, I don't know what I should do? I have a brand new T400-2 and a set of Rockford 6.5" components as well as 5.25" components lying around. What size speaker should be used to replace the factory door woofer? And has anybody tried the Q-logic Q-forms for the S197 yet?
