ok i have searched the forums and i couldn't find the answer to my question.

i have 2 jl audio 12"w6 dual 6ohms 300 watt RMS each. i am looking for an amp that can run these two subs. if i run them in series it will result in 3 ohms. and if in parallel it would be 1.5ohms (correct me if im wrong)i been looking for some different types of amps and they are the jbl bp600.1 rated at 600w @ 2ohms. how many ohms should i setup my subs ? 1.5 or 3ohms? and one more question, will any amp that is rated at 2 ohms xxxwatts work with that setup also? thanks

your resistance is wrong....if you run them in parallel form the 2 subs in parralel  will still have a 6 ohm load.....if you run the 2 subs in series you will have a 3 ohm load......If you are using DVC  (dual voice coil) subs    you can wire each sub to 6 ohms or 3 ohms.......thus giving you  a 6 ohm a 3 ohm or a 1.5 ohm load

(2) 6ohm subs in series are a 3 ohm load

(2) 3 ohm subs in series are a 1.5 ohm load

(2) 6 ohm subs in parallel are a 6 ohm load

(2) 3 ohm subs in parallel are a 3 ohm load

well ok i got this from the jlaudio website....btw mines are dvc's. i have the coils wired in parallel.

https://www.jlaudio.com/subwoofers/pdfs/8-12W6_BDS.pdf

still haven't my question, if an amp is rated 600watts at 2 ohms. and if my speakers were 300watt each @ 6 ohms. what would be the best way to wire up my speakers to the amp. series/parallel? thanks a bunch

Jonjon1 you are correct with the ohm load config. I have my 2 12w6 hooked up in a parallel config. giving me a 1.5 load on a ps series kenwood. Not the best amp but I was surprised with the remarkable pounding sound that it gave me. I have heard good things with that JBL amp that you are talking about. I have not heard that particular one, but it should work out just fine. I had a couple of Orions that were stolen but they were great! They went as low as a .25 ohm load stable. So answering the other question if you had more subs with one amp depending on all you had ofcourse then I would hook it up in series. If only two subs then I would use parallel.

cool thanks Sound Pressure for you advice. also if an amp was rated at 2ohm stable can i still hook up my speakers to it if my ohms were 1.5?

No problem glad to help.

You will put some stress on the amp but not much!

I wouldn't go below the manufactures recomended resistance.  When you check it with a multimeter you'll notice that the subs will actually pull less than 3 or the 1.5 ohms. If you wire them in series pulling a 1.5 ohm load look for an amp that can handle atleast 1 ohm.  Or if you go in parallel try a power bd500

hey thanks for all the advice. i think ill be searching for an amp that will be stable at about 1ohm. maybe the orion hcca 250g4.

I currently have a orion hcca 225 for sale......i might have a 250 in a week or so....it has been used and am looking for about $300 on it.......it has only been used for about a month,  i have changed from that to 2 memphis 1000d's     let me know if you would want it,

hey jeffchilcott, im kinda considering a class D amp now. i dont want to suck up too much power from my batt/alt. and 300 bucks is a lil over my budget. but thanks

What brands are you considering?

audiobahn A8001D

300watts @ 4ohm

500watts @ 2 ohms

800watts @1 ohms

well i dont know much about that amp but looks solid includes 2 cooling fans. but so pricey

Correcting jeff,  wiring each coil in parallel will present a total impedence of 1.5 Ohms...  Wiring the subs in series/parallel (2 coils on single woofer wired in series, and in parallel to the other woofer) config would result in a 6 Ohm load, and a series wiring config would result in a 24 Ohm load.  Now obviously your best bet would be to use a parallel wiring configuration.  Now if it were me, I'd use a  JL Audio amp...  their amps put out the same amount of power between 1.5 to 4 ohms and between 10 and 14V (Gotta love the regulated power supply)...  A 500/1 would do the job...  I really wouldn't recommend an audiobahn or any other no-name amp just because they are so cheaply designed and manufactured...  I know people have their preferences, but our store doesn't even put crap like that on the shelf.  Our lowest line amplifier is a kenwood or eclipse, but we mainly sell Alpine, Phoenix Gold, JL Audio and MTX...  Do yourself a favor and check out what kind of damping factor that amp would have at 1.5 Ohms for one (Just to make sure it's not going to sound like crap like most cheap class D's do), and also see what voltage they test at... Probably not 12.5V huh?  Take into consideration that a voltage drop would severly affect the amplifier's output (And it will unless you have a sufficient charging system).  Also, it is common knowledge that for every 10 amps an amplifier draws the MOST power it is going to produce is 100 watts (If it is effecient), so check out the fuse on the side of it...  Does it have a 30 amp fuse and say it puts out 600W RMS??  Yeah, whatever!  Also, 2 cooling fans don't make much of a difference without proper heat dissipation.  Look at the heat sink... does it do a good job of dissipating heat, or storing it?  If the amp runs hot, it will usually start clipping sooner than it should...  When you take all of this into account, you will realize that you actually pay more $$$ per watt of true continuous power for a inferior amplifier than you would for one that puts out true, clean power and not a whole lotta sqaure waves, plus you have the benefit of great SQ (that's why you bought those JL's in the first place, right?)

hey jellynutz

i agree with you completely. i had the jl audio 500/1 in mind. but if my speakers are rated at 300 each. will i be underpowering my speakers? i want to use the full potential of my speakers. and i reconsidered the jl 500./1 because some of my friends said that that amp isn't good enough.





Posted By: JellyNutz
Date Posted: November 11, 2002 at 10:15 PM

The JL 500/1 really puts out 600w continuous.  When I was at a JL Audio training seminar last month on of the JL reps said they were underrated by 100w RMS.  Your friends obviously don't know what they are talking about, take it from me!  This would be your best bet...

well enough said. i wont mind having a set of speakers and amp with the same label. looks nice also. im going out and getting me the jl amp. thanks alot for your advice. jelly nutz, and that friend i didn't like him very much anywayz.

Hey, I've got 2 10W6's in a bandpass powered by a JL 500/1.  The amp is PLENTY powerfull enough.  You said something about $300 being too expensive.  You are going to have a hard time finding a good amp with enough power for your W6's for under $300.  Don't skimp on the amp.  It is an INTEGRAL part of the system.
