Will a secondary battery and all wires upgraded to 0/1 gauge push 2500 watts rms without alternator upgrade?

Asked by Bcwalbeck Aug 12, 2015 at 02:02 AM about the 2003 Chevrolet Silverado 1500 LS RWD

Question type: Car Customization

I have an 03 silverado with two l7 15" subs on a kicker zx2500.1 amp. Will adding a
second battery and upgrading all wires to zero gauge keep my lights from dimming and
push the amp to its full potential? Would I need to upgrade my alternator to keep them
charged? Thank you in advanced.

If you're experiencing light flicker, using capacitors between the amp and battery will fix that. You shouldn't need to install a second battery.
