No cap in my setup yes I have a deep cycle marine battery in the trunk optima red top starting battery, I actually get away with acceptable drop even with my decidedly weak sauce 175amp alt. I’d keep the isolator I got burned by that not long ago had a stray couple of strands of wire from the hot to the remote turn on for my sub amp and it killed both my batteries.

Nice chart, I downloaded it for future reference.

That wasn’t even a very good one just one of the first I found to demonstrate dude has no clue.

Are you running 8 guage to you DC?

a reply to: Alien Abduct

so after watching the video, i can see it's a dc capacitor, and if i'm not mistaken the negative side is actually charging the cap and sending out the charge, thus sending the power elsewhere.

I would guess your amp is at least 5000watt amp.

the biggest issue is the wiring at that point

If you push an amplifier like that to the max, you will melt those 1/0 wires

Only because it has 8awg direct leads I personally think people go overkill on the speaker wiring not realizing their amp is throwing out higher voltage and is AC so it’s a whole nother beast. If your runs are short to the sub you’ll be fine with good 12awg.

Pleas stop while you’re behind you’re just making yourself look worse.

well I'll be running 3000 watts rms at most so divide that by the voltage which will be no less than 12V so that's 250 amps at most that will be continuously running through a 20' wire that is rated at 350 amps at 100 feet. As far as i can tell it should be good. can you point me to a source that says it won't work?

I don’t know man he might be right better make 4 runs of 4/0

I think you are mistaking voltage/wattage and amperage.

Also I've never heard of and electrical line bursting. Could you point me in that direction?

Burst in the timing since but why yes they can physically burst in a puff of smoke. Know I know all too well about amperage,voltage, power, resistance that are all interconnected and the longer the run the higher the loss from resistance the higher the heat loss and voltage drop causing overheating of the wire. Go look at an ampacity vs distance chart buddy.

Ampacity vs distance, that's a new one. It's VOLTAGE OVER DISTANCE.

a 20' wire

wahhh?

I promise I am trying to help, i have actual knowlegde of wiring and ampacity of wires

We’re talking about current handling of the cable ie voltage doesn’t matter (mind you’re not going I’ver the max voltage of the cables insulation) the drop and resistance are what the issue is.🤦🏻‍♂️

What we are saying is that the wire causes more impedance the longer the run.

an amp putting out 300 amps will put out 300 amps.

a wire that can handle 150 amps will handle 150, beyond that the insulation may start melting.

It's not rocket science, it's simple science.

I provided you with a nice color chart that shows you’re talking out of your arse please refer to it and come back and tell me distance doesn’t matter...

The wire run may cause more impedance, but dont take run length into that account.

If it has X amount of impedance at 1 foot, it has an exponential more amount at 10'.

Don't under-size the wire and burn your car up. Your wiring seems ok after looking at some DC schemes, so you're good there.

It's the wiring. Spend a few more dollars for the next gauge wiring.

Mine just fell as well, because i actually know what I'm talking about and you know about few wires that make things work. You don't understand electricity at all.

Please explain to me how resistance drops over length?
