Subwoofer wire size?

[pmureika 31]

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?

8 awg.

8 awg.

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

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.

[Quentin Jarrell 671]

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?

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.

[garychurch84 127]

multiply watts x ohms...square root the answer

I think I said that right lol

[pmureika 31]

That gives me watts?

[garychurch84 127]

That gives me watts?

output voltage

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 Edited October 14, 2014 by garychurch84

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 !

[Sencheezy 689]

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

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

 

 

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.

I believe that is for 115 volts not 14.2.
