I currently run a 9883 to an Ea4200 4 channel eclipse amp which powers Eclipse SC 8362 Comps in front, Infinity Reference coaxes out back. Alpine MRP M500 powers a pioneer premier 10 shallowmount in a custom box. I guess as I've gotten more into this I keep noticing more things that could be better. Im looking for a user friendly tuning option to clean up some things in my sound, to include boomy bass in my more dynamic blues music where there's alot going on and lots of transitions in the 50-100 HZ range. Also wondering if a time delay would help fix problems caused by mids in door panels and tweets in sails. I know they're too far apart but I hate kicks and I didn't understand the effects this would have on the sound until after the shop drilled holes and threw them in. I also am trying to improve my imaging. Anybody who runs an IMPRINT kid if you could explain how it works and whether it makes a big difference Id appreciate it, id probably upgrade to a 9886 or 9887.
