INFINITY system    I am not rich so this took me a long time and $$$$$$,  but I think now my system is getting close to complete.    Head Unit: ECLIPSE 5506  Front Stage: INFINITY PERFECT 6.5 Components  Front Stage Amp: INFINITY KAPPA 102a  Rear Fill: None currently  Subs: INFINITY PERFECT 12's (2)  Sub Amp: INFINITY BETA DIGITAL 300  
Here's the domain  95 CHRYSLER SEBRING LXi  Few details to the car like tires, rims, new tint, but I'm getting rated on audio anyways. RIGHT
The MAIN component  ECLIPSE 5506 (The need I say any more Head Unit)  I am not an Audio GOD by any means, but if I can give one piece of advice to anyone out there it is out of all your pieces of gear take the most time researching your head unit and get the best you can.  
The INFINITY PERFECT Tweets  are placed in factory locations as of now.  I need help with the whole Imaging thing.  All I know is I don't want kickpanels.    
The INFINITY PERFECT 6.5's as well are still in factory locations.  The MidBass is awesome from these so more than likely they will stay put, but I am considering sealing them.
Here is the Front stage AMP  INFINITY KAPPA 102a running 100w x 2 at 4ohms  good clean power  The INFINITY PERFECT crossovers are set to the left of the AMP  This is all set behind the rear seats.  
The Trunk  2 INFINITY PERFECT 12's  SUB AMP - INFINITY BETA DIGITAL 300 running 500w x 2 at 2ohms  Lightning Audio 1.5 farad cap with LCD Monitor  Tha AMP and CAP are set flush in tire well, with an overall smoth look  I am looking in to wrapping everything in vinyl to match the leather interior.
I still need to soundproof the entire car,  and I am thinking about adding some rear fill with anoter 102a AMP  Other than that a few cosmetics and I am done.  If anyone has any opinions that will help with SQ or SPL  please E-mail me  Thanx
