if you use a block on the ground you don,t need a block that holds fuses

 

I was wondering that. Thanks.

 

fuses are only relevant (sp?) on the power side d-block, Completely wasteful for the ground d-block, a regular plain-jane distro will work wonders

 

You don't "Need" a ground distribution block.
A ground block makes the installation easier and neater. You only have to ground one wire to the chassis (easier) so you don't have more wires running around (neater). But you can ground each amp individually to the chassis, but that does involve a bit more work.

I'm cheap, so I didn't use a ground block, and both of my amps work fine.

Just a note,
You will need a fuse at the battery too. You will have to get an 120 amp fuse (because each of your amps can draw a max of 60 amps). That means you will have to get an ANL fuse and fuse holder, because I'm pretty sure that bus fuses don't come any larger than 80 amps.

 

If I put a 150 amp ANL fuse instead of a 120 amp fuse will it hurt the system in any way?

 

your battery fuse should only be as large as the current carrying capacity of the wire it is protecting. 4awg is about 125 amps, 0 awg is 325 amps etc...Higher than what the wire is rated for can cause a fire, since a short can exceed the wire's current flow and still not reach the fuse's limit. The fuse does not blow, and the wire keeps overheating.

 

I'm glad you told me that, better to know that now than later. This site is great, I've learned so much and everyone is fsat at replying. Thanks to everyone that has helped me out.
