another groud?

i have my amp grounded to my chasis now with the big 3. should i add a ground from my battery negative to amp, if so how big, 4 ga?. and should i leave the ground from the amp to chasis on and just add the second ground right to that point on the chasis?

i also have a 2.0 farad capacitor now, i hear mixed things about these, should i dump that off my setup?

You should be fine with your current ground, and yes dump the cap...

it can probably never hurt to have enough grounds

unless there at multiplepoints in the vehicle, then your creating a bunch of ground loops, and ideal way would be to attach a large gu. wire to the chassis at a good grounding point and run it into a ground distro block and run all of your 'aftermarket' or alternative grounds into that

i didnt mean all kinds of different grounding points, i just meant more runs of wire

Unless one of those ground paths goes through the signal cable, there won't be a problem. Multiple grounds for one comoponent will not cause noise. A bad ground for one component and good grounds for the components hooked to it usually will though.
