How big does the wire really need to be?

 

For 2k of power to a sub.

 

How many amps are you really putting thru the wire?

  • It makes no sense what so ever to run 6ga wire to a sub that sees 2k watts. Especially considering you need to buy double the length to run for + and -.  I just dont understand how that could remotely

    I used 4g on my xcs for a while. I use 8g now because I won a 400 foot roll of sky high at a comp raffle. Some people will go overkill on wires some will not. I didn't need to run 24 runs of shca 2/0

  • I think that is way over kill and a waste of money. That's my opinion.

8 awg.

12 or 10 is fine but imo since wire is fairly cheap no harm if u want to use 8g

Use ohms law to calculate current then calculate what you need based on the conductor's length.

Guessing what you think you need is no good.

You need a much larger conductor for a run of 40 feet than 4 inches.

What is the actual voltage a subwoofer sees from the amp?

 

Is 12 volts ac the max?

Edited by pmureika

At 2k? That depends. Is the sub .5, 1, 2, 4 ohms? There are plenty ohms law calculators out there.

I had it running at 1 ohm load and 12 gauge seemed to work just fine.

multiply watts x ohms...square root the answer

I think I said that right lol

I am not a expert or a enginer , but I don't get it even using the calculators. Because I don't have all the right answers.

2000w X 1ohm =2000 square root 2000 = 44.7 volts

very pointless especially for daily, but it will do if you wanna be cool. As short as subwoofer runs are the bigger wire wont make a difference.

Than volts x watts= Amperage.

I agree with that, It's only for daily use.

 

Thanks a lot !

lol. ok. I'm obviously doing it wrong.

If you think it's way over kill, or an waste of money, then why ask the question? That's a waste of forum space, that's my opinion.

 

You asked for an 2krm subwoofer. Take a look at an SSA Zcon, the terminals are to fit 8awg wiring. So are you saying they made an wasteful decision? What about Obisidian, their OA line allows 4awg, same can be said for B2 with their XC line.

 

It is an safety hazard to have too small of wire. As questin said, use an calculater. You have been on this forum for too many years to be spoon feed for ANY questions  you have, especially when there is calculators readily available.

Your not doing it wrong just spending more then you need to.

 

That's my opinion not fact.

My hds210 sq subs can take 10 gauge. does that mean I need to use 10 awg.

lol. Ok, we can play that game.

 

Crescendo Audio BC5500. Dual 1/0 inputs. So tell me what happens when you only use half the inputs, or attempt to use 4awg vs 1/0.
