I have 2 kicker 12 inch solo baric L5 subs with 1200 watt rms together and 600 individually, a hifonics bxi 1606d amplifier with 1200 watt rms, and a 2001 nissan altima gxe...will the car be able to run ok with all that power or is it necessary i buy a capacitor?
you should upgrade the stock wiring instead of a cap. google the big 3. its bigger wire from alternator, battery and grounds. Usually takes care of most low level system needs. The next steps are a better battery and finally a larger alt. Caps do little to help if your lacking power.
