Topic: wiring 2 ohm subs

Subject: wiring 2 ohm subs
Date Posted: June 07, 2006 at 8:47 PM

    Im thinking about buying these power acoustik subs : https://www.caraudiodeals.com/product_info.php?cPath=21_24&products_id=307

They are Dual 2 Ohm voice coil.

I own this amp  :   https://www.caraudiodeals.com/product_info.php?cPath=28_30&products_id=368

My question is does my amp handle 2ohm? Ive hurd it will only handle 4ohm.  I know that i can wire a single  dual 2 ohm voice coil sub to 4ohm.  Can i hook that one sub up to 1 channel of my 2 channel amp? Or does it have to be bridged?

Also does wiring a 2ohm sub to 4ohm take rms handling power away?

If anyone can help me out with this post it would be great.

Thankyou

According to the amp specs, that amp will safely handle 4 ohms bridged.  Since you already have the amp, look for a couple of dual 4 ohm subs, or just buy one of those Power Acoustics.  Be warned- neither of those brands is known for high quality, so the specs may look good on paper, but may not give you what you want.

The rms rating of a speaker does not change.  What will change, however, is the load on the amp.  Running an amp at a lower impedence will produce more power, but will also create more heat as well as higher THD levels (distortion).  When running an amp at a higher impedence will produce less power, it will run cooler, and produce a cleaner sound.  So there is a tradeoff and it all depends on what you're after.

Thanks for your reply.

All i need to know now is , if i wire a 2ohm sub to 4ohm   how do i connect that to my 2 channel amp? can i put it on 1 channel? or does it have to be bridged?

Im buying 2 of the 2ohm subs. So if i wire them seperate to 4ohms can i hook 1 up to 1channel and the other to the 2nd channel?

I dont really want to bridge it because my amp is 2000 watts max bridged. and the subs are only 1800 watts max a peice.  It might spike them. Plus i dont think i can bridge two 2ohm subs to equal 4ohm, can i?

Don't worry about your amp overpowering those subs.

I high doubt that amp can put out 2000 watts MAX nor can it push 500 watts rms. I'm guessing your a noob. But we all have to start somewhere.

You should buy DUAL 4 OHM VOICE COIL subs and wire each paralleled to a channel.

What is the total fuse rating on that amp?
20? 40? 15?

Yes, you can run 4 ohms stereo- one sub with the coils in series per channel.  If you were to bridge them, you'd need to series all the coils for 8 ohms bridged.  This is electrically the same.

yeah im the noob? you cant even answer a simple question buddy. I NEVER SAID I WANT A 4 OHM SUB. i said im getting two 2ohm subs can i wire each one to 4 ohms and wire that to 1 channel of my 2 channel amp.  i didnt ask what should i get a 4 ohm or a 2ohm, i know 4 ohms are easier.  2 ohms are better especially when i get rid of the lanzar amp and get a legit one. thanks for nothin NEWB.

Hey im guessing your the newb with a big wallet? You go out and spend top dollar on namebrand stuff that only pushes out 100rms per 300 bux for an amp. My buddy has a 1600 watt Legacy peice of shyt amp(100 bux). With cheap ol legacy speakers(30 bux each) in his hatchback civic. It shakes the whole car to peices, he has cracks in his glass. Cant even look into the rearview window because its blur.(149db)

Im sorry i dont work for a living to pay off system debt.

total fuse rating is 40- two 20a fuses

Sorry to bust your bubble but 40 amp fuse is goin to push prolly no more than 500 rms. Still with that amp you maybe lucky to get 300rms.

Don't get sh*tty at us for trying to help you out. If you can read you would know that dual 4 ohm subs would let you get the most out of that amp. Getting crappy with us will lead to no feedback for you.

Also I high doubt your friend can hit 149 with a sh*tty legacy amp and sh*tty legacy subs. I also have high doubts that sh*tty legacy subs and a sh*tty legacy amp can crack your winshield...I know many others here will back me up one this.

There is no way to get a final 4 ohm load with 2 DVC 2 ohm subs. WE ARE ONLY TRYING TO HELP YOU!!

A $300 100 real watt rms amp will blow that piece of crap legacy out of the water.

Sorry for going off but what goes around comes around.

Also I work my *** off so yeah.

Next time just try to take some GOOD ADVICE from us here.

No need to get snappy, especially when you have false information my friend. Why do you say 2 ohms are better. Thats possibly the most broad statement I have ever heard in my life. Do you know what happens when you load an amp down. Your THD will go up, thats your distortion rating. If you were smart you would get your subs as a dual 4 ohm because you can achieve a total load of 4 ohms bridged. That way when you get a "more legit" amp later on you can get a large 2 channel amp and run it at a 4 ohm bridged load to keep your THD lower than what you would achieve with a D-Class mono block.

Now the other side of that coin is that the higher distortion level of a D-Class mono block is probally gonna be hard to hear when using entry level subs like the ones you chose. So in that instance you could use your dual 2 ohm subs to achieve a total load of 2 ohms on a mono block amp and your advantage there is that a D-Class amp is more efficent.

So you see there are pluses and minuses to both ways but Option 1 makes more sense in your case as you already have a 2 channel and this option lets you run your amp in the most effiecent way for now and still leads you with a good option for down the road. Also your excuse about not wanting to "Spike your subs" (which is an incorrect term to start with) doesnt make any sense using the most basic of math. The subs handle 1800 watts max power EACH and the amp puts out 2000 watts max TOTAL so that means that going by the BS stats the companies give you you have 3600 watts of total power handling and only 2000 watts of actual power. Mabye instead of flying off the handle next time you should pay attention and you might learn something and get some advice that will help you out in the end.

Ty for still not answering my question. Again you said..There is no way to get a final 4 ohm load with 2 DVC 2 ohm subs. WE ARE ONLY TRYING TO HELP YOU!!

YOU MUST BE THE NEWB BECAUSE I KNOW YOU CAN WIRE a 2ohm sub to 4ohm,  and put it on 1 channel, i was just double checking with yall but thats the last time i do that . haha

Also im not going to get called a newb by some newb himself.

You said that a 4ohm sub would be better? HOW is it better when i said i can wire a 2ohm sub to 4ohm, ITS THE SAME THING NEWB!! (Who doesn't agree with me on that?)

yes i know that, but it can also take alot more power , i know the sound quality wouldnt be any better. but if i buy the right amp for the 2ohm sub it would hit harder than  4ohm. Im sick of ppl not reading my full post and understanding it.  I never said that a 2ohm sub would hit harder on the amp that i own now.  i said im buying them because im going to upgrade on a better amp. get cha facts stright END OF DISSCUSSION

You need to start using the quote button so I can figure out what the hell you are replying to. Now on to the inacuracies of your latest offering. A 2 ohm sub on a properly matched amp will not hit any harder than a 4 ohm sub on a properly matched amp,so that argument is incorrect and not worth pursuing. And the Sound quality WOULD be better on the 4 ohm driver than the 2 ohm in most instances, whether you can hear the difference or not is another story. I read your full post and understood the full post, but being that you were WRONG in what you said I tried to point you in the right direction.

Ok, I have a question for you that I just want  a strait answer to with no BS. Is the box you are going to use one were the subs have their own chamber or will they be in a shared air space box. Also is it a sealed or ported set up. This is going somewhere but I need an answer to this first before I can go any further

"A 2 ohm sub on a properly matched amp will not hit any harder than a 4 ohm sub on a properly matched amp" 

Again, i never said that it wouldn't. i said that a 2ohm sub would bump harder set up as 2ohm not 4ohm , 2ohm takes more watts from the amp if the amp were 2ohm stable and set up as 2ohm, TY COME AGAIN. (for ppl that cant understand that)... if you have an AMP. and your  hooking your subs up to 2ohms you will get more rms out of your amp. than if you wired it to 4ohm!! but the sound quality would be less wiring it to 2ohm, THEN AGAIN WHO CARES ABOUT SOUND QUALITY WHEN YOUR CAR IS SHAKING.

im getting booted off this form because morons try to prove ppl wrong on everything people post. And i cant try to prove them wrong back? I never used bad language.  Some kiddy called me a newb. and i cannot call him a newb back? lmao the moderator said stop calling him a newb or your account will be blocked.   Thats some funny FFFFFFFFFFFFFFFFFloving doodie dude.. love THIS FORM , I STILL HAVENT GOTTEN MY QUESTION ANSWERD!!!!! ITS BEEN 4-5 DAYS WITH MORE THAN 10 POSTS. NEWBS!!!!!!!

my box is made for the specs  and its sealed .  if your trying to tell me that it will blow apart? think again 1inch thick with steel drywall screws. i didnt come to this post to be asked questions. i was the one asking the question , and still no one could answer it... whats the point of this post then????? cancel it... and kick me off this grimmy ass form because i said newb lmao go cry to mother  maybee she will buy you some more brandname doodie.

Hmmm, I have quite a bit more than 1000 bux into my system and my car doesn't shake.  I guess I was punked. posted_image

The only question I saw of yours that didn't get directly answered was whether you could run two subs on one channel of your amp.  The answer is yes as long as the impedance isn't too low.  Someone did say you could run a dual voice coil sub on one channel which is the same thing, and I don't get why you didn't see the connection to your question.  But at least now your question was directly answered.

Yes the amp can handle a 2 ohm load to each channel. Yes it will handle a 4 ohm load to each channel and if bridged.

Wiring a DVC 2 ohm sub to 4 ohms does not take "rms handling power" away. Most 2 channel amps put out full power when bridged at 4 ohms.

So again...your question is answered strait up.

We are just saying that with two DVC 4 ohms subs you'll get the most outta that amp.

Goodbye.

Ok, I obviously misunderstood what you said about the 2 ohm and 4 ohm, my bad. The reason why I asked about the box isnt cause its gonna blow apart, its cause I had a concern about your set up. BTW You still didnt answer my question, I asked if its ported or sealed, and you answered that, but I also asked if its gonna be chambered. The reason why is because if you are going to run subs in stereo off that amp, which is what it sounds like with the way you talked before, and the box had shared air space you might have an issue. Thats the only reason why I asked, but hey what the hell do I know. Have fun

Why such hostility towards the people of this forum?  We're all trying to steer you in the right direction.  Chill out and stop making such an ass out of yourself.

I don't see one of your questions that hasn't been answered, so what is it you want to know?

dude, this is all pretty ridiculous...everybody needs to calm down here.  Granted, it is true that the equipment homeboy wants to run is economy, i've heard economy systems rock pretty dam hard...20% produst, 80%install.  And i've also gathered that he doesn't care about sq at all, only looking foe ridiculous output.  Don't get me wrong, i'm not taking any sides on this, i'm just saying he shouldn't be ripped on for not buying the best...but i think everybody needs to relax and chill out on this tip, cause it's obviously just wizing lots of people off.  let's all calm down and have a peaceful discussion like adults, where constructive criticism is met with amicability and not hostility.  just my two cents. peace
