Alpine MRV-F450 Car Amp

Done 3 years ago using all 5 channels. Alpine head (CDA-9851) and amp go well with Infinity speakers all around and 10" Infinity bass in trunk of Camry LE. My first install and the amp set up (beginner me) was very complex for crossovers and swith settings - as always comes down to sound you like. Has run very well for these 3 years with superb, clean sound. First upgrade was adding a .5 Farad capacitator; second was iPod cable (KCA-420i) to head unit. I'm amazed by quality of sound via CD; iPod or FM. Just now upgrading core audio by moving door speakers to floor kick panel sound enclosures. Hope to move sound to front of vehicle instead of sideways from door panels - Face the stage. I did a "jump in with both feet" solution using Alpine and Infinity. Infinity Kapppa perfect 10.1 bass; Kappa 6X9 692.5i 2-way back; 6.5"component front.
