capacitors

Parallel. Simple as that. Be sure you charge the cap corrctly, I use a test light. Remove underhood fuse from it's holder, connect cap(s) and amp(s), place testlight in-line under the hood where your underhood fuse SHOULD be (and had better be). When test light goes OUT, and I mean OUT, re-install the fuse. Battery positive to cap, onward to amp. Chassis negative to cap, onward to amp. (You can also run (effectively) from amp to chassis to cap negative also. Some installers will do it this way, I prefer the chassis-cap-amp method - shorter path to amplifier power input.)It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
