It generally won't matter... I personally ground to the cap, because it's fewer physical connections in the current path between the cap and the amplifier.

*IF* a cap can do anything truly helpful in any system, then ELECTRICALLY you want as few physical connections between the current source (the cap) and the current sink (the amp) as is possible.

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."

is using a voltage meter necessary? i grounded my amp to he amp i think it sounds a "little louder". not sure though.

would it be a good idea to get a distribution power block so i can connect my 4 channel's power wire directly to the block instead of being connected to the cap? because right now im using 8 gauge wiring for both amps (mono amp & 4 channel amp), and they are both twisted inside the cap. and i can upgrade a 4 gauge power wire from my mono amp to the cap. good idea or what? thanks.

If it were me, i would ground each device with the shorted possible wire. Ground the cap as close to the cap as you can, and ground the amp as close to the ground input terminal as you can.

let;s try this again. I asked how short you could make them. You told me how long they were. So if I ask you how long are they, are you going to tell me how short you could make them?

One foot is not bad, 2 feet is only half as good as 1 foot.. But the shorter the better. Length = resistance Resistance = voltage drop. Voltae drop = less power
