SoloBaric/JL Wiring Question.

[SHawk670]

I just ordered 2 Kicker Solo Baric 12inch 2 OHM Sub's to replace my old JL-W3's. I though with the Kickers, the duel 2 ohm subs wired in Paralell would produce a 1 OHM load to the amp, my MA-Audio can't run any thing lower than 1 OHM. On the kicker webpage it says that would produce a 2OHM load to the amp, while JL's web page says that 2 DVC 2ohm subs will provide 0.5 OHM load to the amp, that's a sure fire way to fry my amplifer. I've never messed with these crazy Square SoloBarics and already im kinda wishing I spend the extra money on some JL-Audio W7's. So should I order 2 4 OHM L7's or stick with the 2 2OHM L7's. Thanks.

you'll love your solo barics, trust me :) i have 2

what you want to do is wire each solo baric in parallel, that'll take it down to one ohm per sub (following me?)

then you want to hook both "1ohm" subs in series, that'll give you your 2ohm load, (still with me?)

thats what you call series parallel wiring, there are alot of wires and it can be trick to do, but take your time, make it neat and POUND LOUD :)

do u have the L7's or L5's? and also what amp you got?

[SHawk670]

That's kinda what I was thinking. But is there any way to get it down to 1 OHM using 2 Subs? I have an MA-Audio SY7011DX. It put out 1000 Watts RMS @ 2 OHMs, or 1500 Watts RMS @ 1 OHM. I guess I can live with 1000 Watts, but if possiable I want to get the full 1500.

with dual 4ohms subs you can, but with dual 2 ohms you can olny get down to 2 ohms :(

or add another sub and get 1.33 or 1.66 i forget which, i'd try to go for dual 4ohms to get your 1ohm total and pound like its meant to be

I seriously doubt that that amp makes 1/3 more power into a 1 ohm load, that's marketing. Lower impedance is never benificial. Wire the amp to 2 ohms, you won't here the difference, but your amp will be much happier, trust me.

I would, however, recomend wiring the voicecoils on the woofer in series (for a 4 ohm load) and then wiring the subs in parallel (for a 2 ohm load) rather than vice versa, ESPECIALLY if they share a common chamber in the box. ;)

What makes you say that? On an unregulated power supply, the lower the impedance, the more power you can get usually. Yes, the amp has to be capable of playing with such a low impedance, but if it can, why not run it?

why do u tend to say do it this way? just wondering your train of thought

Quinton - Being stable into 1 ohm is fine, but several things happen when you drop the impedance. First off, your efficiency drops. No way around it, it's gonna happen. More heat, less efficiency. Secondly, your damping factor drops DRASTICLY. Lower resistance, less abillity for the output devices to control cone movement. Thirdy (related to first point), more current draw equals lower constant voltage from the charging system - in other words, any benifit you got powerwise by going to a lower impednce goes away because of lower voltages - ESPECIALLY on an unregulted supply. Add to these points the fact thast most amps that claim to put out more power into lower impednces DON'T (there are exceptions), why bother? If all was right in the world, all amps would run optimally into 4 or even 8 ohms, but that's not the case. In the meantime, keep it at 2 for most mono amps for maximum performance.

grass - when you wire two speakers in series, there is a slight phase shift between the two. Not a HUGE problem, but it is compounded in a common chamber system. Add to that the fact that's it's just as easy (if not easier) to series the coils at the speaker, and why wouldn't you? :)

[quinton]

Yeah, I know that the lower you go the more heat and stress you are putting on the amp. I was just saying for competition purposes, there IS a reason people run down into the .25 ohm range and such. In a daily driver setup, ofcourse it might not last very long. But for raw power, lower impedance CAN be benefical, assuming you have the electrical system to back it up.

According to the kicker Tech Manual (http://www.kicker.com/images/manuals/02SL7TechManualV2_0.pdf) Using 2 Dual OHM Voice Coils will provide a 1 OHM per woofer resulting in a 2 OHM load to the amp. While under there it says that dual 4 OHM amps will provide a 4 OHM load to the amp. So Grass, how would I get the 2 4OHM subs down to 1 OHM? My friend get's these Wholesale and only really resales them so I can change my order no problem and he'll just sell the 2 OHM ones I never used. I've got 2 4 OHM JL-Audio W3's at 1 OHM so I know my amp can take the single OHM no problem, the only problem im getting is that there's too much power is being thrown to thoese poor JL's, while there not ripping or blowing like a cheap sub, they just sound really distorted and make a flapping sound at higher sound levels. Like I said I can live with 2 OHM it puts out plenty of power, but if I can get to 1 OHM im going to do it.

[grass]

you hook each four ohm sub in parallel to get it to 2 ohms, then you hook both parallel'd "2ohm" subs in parallel again to get 1ohm,

make sure AmIGrand agrees, hes only a little bit smarter :rolleyes: :D

so quinton quoted AIG, but i didnt see his reply, wtf is going on?

Exactly.

SHowK - you won't gain anything by running that amp at one ohm, that's what I'm trying to tell you. And with 2 woofers with dual 2 ohm coils, you either get a 2 ohm load, a 8 ohm load, or a 1/2 ohm load. For a single 1 ohm load you'd need 2 woofers with dual 4 ohm coils.

Hey hopefully this link will help you. http://www.edesignaudio.com/ep/wiring.htm Check that out. Elemental has awesome subs by the way.
