Hey guys, I need some advice on grounding multiple amps. Right now I've got an Alpine MRV-M500 powering a 12 inch Kicker L3. I'm going to get an Alpine MRV-F300 for mids and tweeters in the near future and just want to clear this up so I'll know what to get.



I have a (supposedly) 0 gauge CCA cable (i think) which will go to a distribution block and split into 2 4 gauge wires (hopefully will fit the F300).

Now here's the question: should I do the same thing with the ground ? the 2 4 gauge ground wires from each amp to a distribution block and my current ground cable (also 0 ga of course) ? Or should I ground the 2 amps to the same spot without the distro block and without the 0 ga ground cable ? I know that you're supposed to have the same thickness of power and ground cable...

 

As long as the actual in and out wires are the same size that is what matters. The shorter the run the better.



I like using one of these for a ground block. as it grounds to the frame also.

 

Worked fine in my 350Z:

 

power and ground blocks are what ive used in many builds
