I just want you guys to tell me, if I got my wiring here correct. I will be getting a 400 rms amp and have to supply power to it. I currently have another 300 rms amp and it gets power from a 4 gauge power cable and is also grounded by a 4 gauge cable. Now, I'll have to get a fused distribution block and connect my main 4 gauge power cable into the block and run 2 power outputs to my 2 amps. My question is, should I run a 4 gauge from the block or an 8 gauge? If I run 8 gauge, is it ok to leave my current ground wire at 4 gauge if the power one is 8 gauge?

And for the fusing part...One amp uses a 60 amp fuse, the other a 40 amp fuse. So I put same size fuses into the dblock and a 100 amp fuse near the battery? Am I correct?

Everything sounds good in your design, and I would suggest using 4 ga from dist block to your bass amp, while 8 ga to your mid/high amp would probably be alright. You could leave the grounds at 4 ga for the bass amp, and go with 8 ga for the highs, and you'll be fine. Just keep your grounds as short as possible(18-36" preferably). and your fuse plan looks good too. Good Luck.

Remember the Heroes. Let's Roll.

If it don't fit, Force it.

If it breaks, You needed a new one anyway!

Correct with the fuses. I would use a 4gauge line if possible to the larger amp. Nothing wrong with having a ground wire that is larger than the power.

Top Secret, I can tell you but then my wife will kill me.
