...being a different Ohm? I know how to do it on a DVC subwoofer, but is there anyway to do it on an SVC speaker? Like, drop a 4 Ohm speaker to a 2Ohm load?

yeah, add another 4 ohm svc sub to it :D

You can add a 4 ohm resistor.But I would only use that for mids/highs.

yep get a second svc 4 speaker and wire them in parallel

So, if I had 2 6x9's I could trick them into running a lower ohm (both would be 4 Ohm) by running a setup like I would with a 4Ohm DVC subwoofer?

Yeah. Two 4 ohm speakers can be wired to a final 2 or 8 ohm load.

Check out a woofer wiring wizard.

If you do that you will lose your left right fad capabilities.

There wouldnt be a left and right anymore though. Just remember that.

If you're trying to get more power that way, it's not worth it.

So, like this but with 2 separate speakers:

Wire in a 4 ohm resistor.

The only catch is, the resistor will get half the power. So you're back to square one.

Bottom line, you can't.

Well, I'm rigging them to work with a Bose system that uses 2 Ohm speakers :D It's only a temporary fix until he (my friend I'm working on his car audio for; Blown rear paper speakers) gets the money together for the front components and a HU to replace the craptastic Bose.

Just buy some cheap tweeters and hook them up.They'll drop your ohm and give you some added sound.

It's a rear deck setup, so that would detract from soundstage. I'm using Type-S 6x9's that have a silk tweeter already and not happy about, but they fit the bill best cost vs. need. When he gets the new HU and front components, I'll see if he wants me to add an in-line Low pass filter to the rear since the original 6x9's were just woofers with no tweeter. We will see when it gets to that point. I have extra wire laying around so wiring them to 2-ohm would be free and a decent temp solution to output issues IMO.

If the amplifier is already stable to 2 ohms, running a 4 ohm load on it is not going to cause a problem.

You can add a 4 ohm resistor.But I would only use that for mids/highs.

Even if you did this, the sub would still be a 4 ohm sub. It would represent a 2 ohm load to the amp, but the resistor would be absorbing (and heating up with) the extra power. No amp is perfectly efficient either so if you did this, the sub would more than likely not be getting as much power. Think of an amp that does 400 watts at 4 ohms. That amp will more than likely do about 600 watts @ 2 ohms. What you're doing there is taking a sub that will be getting 400 watts rms, wiring it in parallel with a 4 ohm resistor, and then feeding it 300 watts rms. If you add another 4 ohm sub, at least you'll be doubling the surface area of the woofers so it'll be louder.

Oh I know there won't be an issue under the 4 Ohm load; however, I would like him to get the most use for his buck and if it's a free upgrade to output until he gets the rest of the setup, why not do it :D

The stock Post-amp for the Bose system is 50 watts peak, so cutting it to 25 peak would be a bit of a hit over his stock papercones. To head off the reason why I'm no replacing stock speakers; 1.) They are paper cone 2.) they don't make them anymore....like at all 3.) If they do exist, it's gonna be at a dealer and cost alot, just replacing the stock itty bitty amps is $140 each :eek:

just a put a 4 ohm speaker in there

i can almost promise you will not notice a difference in 10 watts if that might ewven be 3-5 watts diffrence

if anythign the 4ohm speaker will sound better than the factory

if you tell it that it is a 2 ohm speaker enough, it will become a 2 ohm speaker.

Sure it's pretty easy actually

1. remove the speakers from your car ( you could leave them in if you have access to a pool or pond)
2. Scrape of any nomenclature saying they are 4ohm
3. Soak the speakers in water. How long depends on what final impedence you want them to be. To go from 4ohm to 2ohm, you would need to soak them for only 2 and half hours.
4. Put them back in your car and enjoy your new more powerful speakers

This sounds like the way to go. I think I'm going to take out my Focals and drop them to 2 ohms later on today...:D

you are not gaining anything by wiring the speakers together. you will only be using 1 channel of the amp to drive both, so you will have the same output as if both were connected on their own.

using your numbers and making it simple....

stock amp is 50w per channel at 2ohm

speakers wired down to 2ohm on a single channel of the amp = 50w / 2 speakers = 25w per speaker

speakers wired on their own channels at 4ohm on a 2ohm amp = 25w per speaker


all you are doing is losing the ability to fade left to right. you are not gaining a thing.

Ahh, there might be a misunderstanding then. Each individual speaker has it's OWN mini-amplifier attached to it...so it would be 2 amplifiers and 2 speakers.

nineball
07-18-2009, 10:57 AM
it doesn't matter. you will still only get 25 per speaker.
