Sae-1000D Wiring ???

Hello All, Im finally going to install my amp I bought a few months back and have a few questions. Let me start by telling you were Im at. Im going to be installing an Sae-1000D amp powering an RE SE 10" rated @ 600watts @ 2 Ohms. I also have a 4 ch PPI amp bridged 160 watts running my front components. The car currently has 4 ga wiring. Would 4 ga still be enough to run the 1000 and PPI amps. Also what size fuse should I use for the power wire.

Thanks in Advance,

Mike

 
fuse your wire based on the wire, not the amp.

Personally i would run 0 gauge and then split it into two runs of 4 gauge at the distro block, one run for each amp.

I honestly don't know what you mean when you say would 4ga still be enough to run the 1000 and PPI amp... do you mean one run of 4 ga for each amp, or one run of 4 ga for BOTH amps.

If you mean the first one... then yes 4 ga is enough and fusing for 100-120 amps will be fine and keep you safe

If you mean the second one... no... that is a bad way to do it.

 
Thanks for the info Alpine. Yes Im talking about #2. I already have a run of 4 ga going to the back of the car to the distro block. I would like run 4 ga from the block to the SAE and and an 8 ga from the block to the PPI. I was trying to not rewire 0/1 from the battery to the distro block if possible.

 
put the distro block by the battery, not in your trunk.

and fuse bat+ to amp + to your amp's fuse rating, not for the wire.

You fuse the Alt+ to bat+ based on wire rating, because you do not want the wire to catch fire.

You CAN fuse the bat+ to amp+ based on the wire rating.

Doing this will prevent the wire from catching fire.

But long before the wire catches fire, your amp will have been fried.

Because of this, you fuse your bat+ to amp+ based on your amp's rating or lower.

This will prevent your amp from being damaged.

This is a normal setup:

bat+ --fuse--------------fuse--amp+

This is a short circuit with a fuse rated for your amp

(xxshort circuitxx) bat+ ---xxfusexx---------------fuse--amp+

This is a short circuit with a fuse rated for your wire

(xxshort circuitxx) bat+ ---fuse---------------xxfusexx--amp+

As you can see, the fuse by your amp will protect it, but it is a close call.

Its safer to fuse for your amp farther away from the amp, as there are cases where the amp is damaged even when it has fuses, having another fuse is added insurance for your amp

this is a short circuit without a fuse
