Power/Ground question...

Doesnt really matter if you groun them together or not, really, it doesnt. Why would it? Someone up there mentioned frying your amps, thats funny.

The only thing I am worried about is the 8awg for power to those amps. Are they meant to use 8awg or 4awg? If they pull alot of current that 8awg may be a little small depending on the length ofthe run.

The length of 8 gauge shouldn't be but ~1 foot. Yeah my Memphis amp takes up to 4 gauge. My Crossfire amp takes down to 8 gauge, but has had 10 on it before fine.

Another question. Would it hurt anything to mount these on the back of my cab? It is metal surface so?

Youll be fine, just wantch for a lot of rattles, it could damage the internals. And make sur eno strands of that power/ground touch the bare metal surface.

Ok..i'll some rubber washerage between, that work for the rattles anyway? Hell my truck rattles everywhere though...

It will be better then nothing. Do you do a lot of off-roading?

Nope, not at all...

The term for grounding in the same spot is "common grounding" it is a recommended way to ground amps to further reduce the possibility of ground loops, but if you have no proplems with a ground loop there is really no reason to change it.

x2

that is almost exactly how they say it in the MECP study guide, but those were my thoughts exactly.

Ok thanks fellas...

heh kinda funny to see all the bad advice.... but I agree with the above few post that grounding to same spot isn't bad...

I had grounded all my stuff to different places and I have a ground interference loop in my FM signal. So I am grounding to the same spot.

It wont hurt anything mounting one amp to the back of my cab will it? And one under my seat?

no it won't matter, one might get shaken a bit more.. but will probably be ok
