4 gauge amp 0 gauge amp power

[pandas]

Hey guys new to the forum and new to car audio installation. Thanks in advance for any feedback.

I'm wondering how I should set up my power runs for 2 amps that each take a different gauge power wire? I have:

Mechman 240 alt

1 XS Power DS3400

Crescendo Bc2000D : takes 0 gauge power

RF R300-4 : takes 4 gauge power

Right now I have a single shca 1/0 power wire running from front to back where the amps are. Should I just use a distro block in the trunk or should I run a separate 4 gauge power wire to the battery up front for the RF R300?

Thanks again

Use lug fuse blocks...

If you are asking if you have to run wire from the front battery to the 4ga amp, then no. If you have a battery in your trunk, you can run your 4ga wire directly to rear battery. you can use a power block but make sure to fuse it.

Thanks appreciate the help

I see a lot of fused blocks that splits a 1/0 to dual 4 gauge. Would that be bad for the crescendo amp which has a recommendation of 1/0 gauge or will the 4 gauge be enough for both amps?

If the amp has 1/0 then you would want to run 1/0 to it. Find a different block or use a block that takes ring terminal lugs. Also make sure to fuse the battery at the rear 1/0 that goes up front. In the event of an accident, a pinched cable will need to disconnect from both batteries.
