Dual 2ohm or dual 4ohm?


HCCA 10-Inch Dual 4 Ohm Subwoofer

or

HCCA 10-Inch Dual 2 Ohm Subwoofer

gonna be powered by 2100W Class D MonoBlock BRZ Brutus Series Car Subwoofer Amplifier.
whats the main difference between the dual 2 ohm and 4ohm and why? thanks in advance

Well, first of all, you do not need that much power for an HCCA, if you aren’t careful and you don’t know how to set your gain(level) you could easily blow your (expensive) sub-woofer with that amp.

The Brutus BRZ series amplifiers are all 1-ohm stable, so in order to get the most output from your amplifier, you want to run it at the lowest stable impedance. The series/parallel wiring options for a dual 4-ohm woofer are 8-ohms or 2-ohms. The wiring options for a dual 2-ohm woofer are 4-ohms or 1-ohm.

Go with the Dual 2-ohm woofer and wire it like this: http://www.rockfordfosgate.com/rftech/wo…

Now, the HCCA 10″ can only handle 1500 watts RMS… that BRZ2100 will do 2100 watts into a 1-ohm load. Which is okay if you have the money to buy the amp and you set your gains right. But a cheaper option would be the Hifonics Brutus BRZ1700.1D. It will do 1700 watts @ 1-ohm and costs like $~60 less.

If you want to understand more about impedance (ohms) read this: http://answers.yahoo.com/question/index;…

Here is a guide on setting your gains properly: http://www.thesuicidaleggroll.com/gain.h… (method 3)
If you get the Dual 2-ohm sub and wire it in parallel your final impedance will be 1-ohm. So it doesn’t matter which amp you get (the BRZ2100 or the BRZ1700) because you will be setting your gain so that at your MAX listening volume on your head unit the amp will only be putting out 1500 watts RMS (any more will damage your sub-woofer)

So in this case:
V = sqrt(power*impedance)
V = sqrt(1500*1)
V = 38.73

Good Luck!

dual 2 ohm is going to pull more power from your amp but it depends on how you wire it. you can wire a dual 2 ohm so it looks like a single 4 ohm or 1 ohm on your amp which might be ideal, look at your amp manual to see if it can handle 1 ohm, or you can wire a dual 4 ohm to read like a 8 ohm or a 2 ohm sub. hcca’s are beast btw, nice.

i’m no electrician yet I actual have examine a lot approximately audio equipment. i could think of a twin 2ohm could make it 1ohm. The decrease the ohmage the extra capacity the speaker will suck from the amplifier. it truly is needed purchase an amplifier that incredibly is stable all the way down to those low ohms, in any different case, it is going to likely be ineffective and probable possibility blowing your speaker besides. decrease ohmage = extra capacity, and with that a lot capacity you’re able to choose capacitors. reckoning on your economic enterprise account, if you obtain it then choose for it, once you’re tight up then i could choose no longer a lot. seek for a speaker without a lot stiffness, the extra stiffness the extra resistance, the extra resistance the extra capacity it is going to take to push it to equivalent overall performance. So i could propose a subwoofer that’s no longer made out of the super stiff textile that many makers use just to make the speaker look heavy accountability. it truly is often in common terms a capacity hog and often no longer as sparkling of bass. the terrific place to spend the money is on the container. A container makes all the version. seek for sound deadening supplies to decrease status waves. additionally, a great container tuned properly and with the splendid application could make a smaller woofer sound spectacular.

neither. way overpriced. an not very efficient.
