Grounding to Battery
Is their any cons to running a ground back to the battery besides the cost of the wire? I will be running 3 amps, 2 - JL HD 750/1 and a JL HD 600/4.
If I ground in the normal location I may be running a longer ground than is recomended, so I was thinking I would just run a ground from the battery when I run my hot.
Any reason this is a bad idea? I just dont want to deal with any ground loops or "engine noise" so why not nip it in the bud from the get go?

Where will your amps be mounted?
In general, you should make the ground wires as short as possible to help prevent noise in the system, however, if you ground all 3 at the same point it shouldn't really matter much where that point is.

I know about keeping RCAs away from power wires and such, and you always hear about bad grounds, so I wondered why no one just ran a dedicated ground. If it doesnt fix a problem they why do it....
Thanks,

I just did exactly that. I had terrible amp feed back. The rca wires were not top of the line
but not cheap ones. Same setup in another car no feed back.
Anyway, I replaced the rca wires with high end ones from radio shack... I know..
but they actually had a nice set.
I ran the rca wires on the passenger side, power and ground on the drivers side.
Not a bit of feedback this time.

That being said, I will go ahead and run the ground all the way, mostly because I already have the wire and distobution block to do it.
Thanks for the advice,
