Ohm subwoofer question

i have an amplifier that puts out 600watts @ 2 ohms for a subwoofer.

does that mean if I wire 2 subwoofers that are 4 ohm 300 watt subwoofers in parallell then i will achieve the 600watts @ 2 ohms?

i am under the impression that wiring parallel for 4 ohm Voice Coils = 2ohm Load?

 

yes, wiring two 4 ohm loads in parallel will result in a 2 ohm load. but that doesn't double the power rating of the subwoofers. they're still 300w subwoofers.

i've run 150w-rms subs on 500w with zero issues, but i'm also extremely conscious of the limitations in usage and tuning. YMMV.

 

thank you bro

 

SVC 4Ω parallel = 2Ω yes, but there aren’t many SVC subs on the market anymore. Be sure they are SVC or get two DVC 2Ω subwoofers to end up at 2Ω.

 

there's absolutely nothing wrong with only running 1 voice coil on a dual voice coil sub either, so if you've got a 4ohm dvc, you can still get a 2ohm final load.

 

if i get 2 subwoofers with dual voice coils @ 2 ohms how would i wire it to still have 2 ohms? i was under the impression 2 subwoofers at 2 ohms wired in series would be 4 ohm or wired in parrallel would be 1 ohm

 

You series the voice coils on each sub to 4Ω then parallel the two subs to bring it back down to 2Ω.

 

ah didnt know you could do that. not sure i know what that looks like either lol. would that be red to neg/red to negative at the speaker and red to red/black to black at the amp?

 

I added an image for you in my previous comment.

 

must have posted at the same time. didnt see. thank you man

 

Sure but there are consequences. You get half the power handling and the theile small parameters are not the same. It’s best to just buy the right subs for your configuration and use all of the coils.

 

sorry, but how does running 2 coils in series result in allowing double the power rating?

not arguing the t/s parameters, they do change, just as they change if the posted t/s were with parallel coils and the end user runs the coils in series.

the fun thing that can be done with single coil on a dvc is a potentiometer for altering the driver Q, though it does result in slightly more thermal loading.

 

Power ratings are typically given for the sub using both coils. If you only use one coil you halve the power handling because you are only using half of the available voice coil, meaning half of the available copper to spread and dissipate the heat.

Likewise, you can increase your power handling by adding more subwoofers (more coils) because there is more copper there to spread and dissipate the heat that is generated. 1000W amp, two 500W subs, totally normal. Now take one sub out. That’s what using only one coil would be like.
