I have a 96 Oldsmobile Cutlass Ciera with a 160 amp altenator, 1000amp Duralast Gold battery, 2.5 farad digital cap w 4 ga wiring. My quad 12 sealed enclosure has a 1.4 cu ft of airspace per woofer. Do I need to add something else to my car to power my future system and entire car at the same time?
