I agree with most everybody else in here. Caps are useless, a small kinetik car audio battery would do more than 40 capacitors. I had a 94 Mitsubishi with a 60amp alternator with 2 kx400.1's strapped and a 240w 2 ch. on the rear 6x9's. Big 3, big wire etc. and I would get so much voltage drop on a hard hit it would shut off the HU....put a second battery in the back corner of the hatch and it would hold atleast 12.2v through any hit even with the 60amp alt. Go see how many caps you see at a car audio comp.
