Phoenix Gold Phorum

I bought the Xenon 600.1 because it's ability to produce the same amount of power regardless of the load. However, all the literature states this to be the case for loads between 1 & 4 ohms. What about 12 ohms?

I'm curious because currently...I have 2 Xenon 10D2's hooked up to it for an overall 2 ohm load. I have a 3rd one that I am considering adding to the set up and I wonder if it would be better to wire everything for a 12 ohm load or a 3 ohm load.

Any suggestions???

Definitely do a 3 ohm load. The Xenon will not make the same power at 12 ohms. They can also be wired for 1.33 ohms, but 3 ohms will be better and still make the same power.

Thanks for the feedback. That's what I was thinking, but I just wanted to make sure I was on the right path.

3 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 4 Ohms
Dual-4 Ohm Subwoofers: 2.67 Ohms
Dual-2 Ohm Subwoofers: 1.33 Ohms
Dual-1.5 Ohm Subwoofer: 1 Ohm

Dual-6 Ohm Subwoofers: 1 Ohm
Dual-4 Ohm Subwoofers: 0.67 Ohm
Dual-2 Ohm Subwoofers: 0.33 Ohm
Dual-1.5 Ohm Subwoofer: 0.25 Ohm

I don't see where you get a 3ohm load based on the descriptions above taken from JL's website unless I'm missing something?

Well...I went to the web site the12volt.com and I plugged in the info. If I wire each sub in series to make it a 4 ohm sub (each is a dual 2 ohm sub) then if you wire them together in parallel...it creates a 12 ohm load. I've always known that parallel wiring divides the impedance and series increases it.

The 3 ohm load comes in if i wire each sub in parallel to create a 1 ohm load and then connect all 3 to the amp in series...you end up with a 3 ohm load. 1 + 1 + 1 = 3 If I wired them in parallel to the amp...then the amp would see .333 ohms.

if you wired them series it would be a 12 ohm load.

exactly what I stated in my original post...I was just clarifying to the person that wanted to know how I came up with the numbers I quoted. If each sub is wired as 4 ohms individually and then wired in series to the amp...that's a 12 ohm load. I just wanted to know the X600.1 would handle that or would it be better to go with the wiring configuration to create a 3 ohm load.

this hasnt been tested in a setup quite like yours...but there is a trick used by some competitors to make the xenon's put out more voltage by tricking the amp into thinking it has a lower load then it really has. the xenon detects the load upon start up. which determines how much it regulates its rail voltage.

this would potentially allow you to run at 12ohms, and get 4ohm power. if you are interested, investigate a little further before implementing

Looks a little more complicated than I care to get. As I've been running a 2 ohm load on the amp for the last 4.5 years with no problems...3 ohms shouldn't give me any problems. If anything, slightly more stable than 4 ohms. I appreciate all the feedback. Once the weather is better on a more consistent basis...I will begin my 2 to 3 sub change and keep you posted on how it goes.
