So I have a 4 ga amp wire running along side the passenger side of the car to the trunk. I am reading a bunch that running speaker wires next to the power wire can cause a lot of noise. Is this true? should I not be running and zip tying my speaker wires to the power wire?

What would be the alternative? run all the speaker wires to the driver side and bring them back that way? Is anyone actually running it like that? or is it fine next to amp power? The power wire is a jl cable and heavily shielded if that matters

I ran the power down the center and the speaker down the sides. Pushing enough power you will notice it... Run separate when possible.

hmm interesting idea. so just rip up the center console and route it through that way? go under the the carpet and in the middle under the back seat?
will it affect the headunit wires at all?

The induced noise received follows the inverse-square rule, so the amount of noise received at 1 cm is going to be significantly higher than 1 meter of separation.

I run the audio down the center console and power along the passenger's side.

Which headunit wires are you referring to?

the stock one, wasnt sure if the loom ran down the center or not but after thinking about it im pretty sure its run down the driver side

also as a follow up question instead of posting a new thread, should the ends of the power wire be tinned before being secured in the distro block? so just flux then tin them and then screw it into distro block / fuse block?

Don't tin it. The copper of the wires is a better conductor.

My subs kept bumping nonstop when there was no music. I separated my RCA wires from the power wire problem solved. It was a PIA switching the RCA wires to the drivers side but it had to be done.

so just bare wire and twisted? i feel like the bare wires keep coming loose from the distro block, the way its locked in is a pinch screw thing. just compresses the wire and holds it in place but the fact that the wires are loose it is never completely secure.

Wire the low gauge wire in a way that it pushes itself in with the weight of the wire. Mine were routed like a U such that the wires came up from under and pushed in with the force of the loop if that makes sense.


A wire untouched Should not be an issue. It's when things get tugged.

Genius! Makes total sense. I'll try to route it in a way that does this

Don't rely on weight of the wire, if it's not crimping it tight enough, put a spacer on the underside of the wire, such as cutting an inch off the wire and shoving a few of the strands from it in there before you screw the thing down.

Makes sense, but at wire this big it should not be a problem .

Nope, it just sounded like it was a 4 gauge wire in a 0 gauge hole.

yeah the distro block accepts 1/0 to 4 ga so I guess im on the small end of the spectrum which is making it a little tougher
