Hi,

I will need 1/0 AWG to handle the amplification planned for my system, running at around 1600-2000 RMS.

The problem i have is that 1/0 is so chunky, and may cause problems with running under carpet, down sides, through firewall etc... i'd prefer 2 runs of 4AWG due to it being flatter. Obviously 1/0 is neater. The 1/0 power pack from stinger looks pretty sweet.

Q1: Would 1x1/0 AWG handle approx. the same current/voltage requirement as 2 runs of 4AWG? They have approx. the same number of copper strands.

Q2: Would there be any inductance issues due to the parallel power flow so close? I'd imagine not as there is no "signal" to get altered due to the EMF created through the power cable.

Q3: Any noise or grounding loop issues?

Any suggestions for placement of the 1/0 would be appreciated.

The only real issue with using dual power cable runs is they need to be joined at boot end of run. I have seen problems with this that we cured by joining cables at amp/boot end. The problem was noise due to different resistance in the 2 cable runs, fuse holders, etc. I would go 1/0 as the only fuse holders etc for this size cable tend to be less resistive than many available for 4 awg. You will spend a little more and the bulk is an issue but you will end upth a stronger voltage at amps most of the time.

I think 2 runs of 2 awg would equal 1/0 awg not 2 x 4 awg. SO to be equal you would need 4 x 4awg.

There are no EMF issues, the only issue is the inductive/resistive noise issue, that is easily fixed by joining cables at end of run

Two runs of 4 awg is roughly equivalent to 1 awg.
Two runs of 2 awg will have less resistance than one run of 1/0 gauge. (two runs of 3 awg would be roughly equivalent to 1/0 awg)

There are no noise issues, in fact I have two runs of 4 gauge in my car at the moment. (they are joined at the end of the run)

1/0awg should be pretty easy to install, esp in late model cars.

what sort of car?

1998 Subaru Liberty RX.

I only got the car last weekend, so haven't taken it apart....yet I have ordered a few packs of serenity max and will hit the doors and boot over the holidays. I plan to get the car prepared with SDing and cabling, so i can just plug the gear in when i get it.

Run the 0 gauge, you won't regret.
Look for the most flexible you can get, becomes an issue with many installations.

Get a good idea what is going in where you put things: some amps have cables in either ends, some all along 1 side etc, be a damn shame to come up short somewhere when you think "perhaps it needs to go over there" etc.

Seems like a smart plan tho'.

whilst i'm not familiar with the ins/outs of the liberty, i'd be extremely surprised if you couldn't route 0awg powerwire through that car.

so i'd also suggest going with that (if indeed you need wire that thick) rather than twin runs of 4awg. alternatively you can find some 2awg if that'd be adequate.

good luck
