You posted this question in another thread on May 2, and DYohn suggested "If what you are looking for is better SQ than you have now, forget about JL altogether and listen to a JBL W10GTi, a Nakamichi SP-W1000D, an Eclipse Titanium SW9102, or a Planet V10D."  

Then forbidden "I would choose a dvc 4 ohm sub and wire it up in series. This will make it an 8 ohm sub and knock the amps power back to something reasonable so that you can actually listen to the music. The JL is a good sub, personally I would head in the direction of one Eclipse Aluminum SW8102dvc and build the proper 1.25 cu.ft sealed enclosure for it and play away to your hearts content."

Have you listened to these yet and if so are they eliminated?  And, as asked before me, why the dual 2 ohm option, when it will only give you 4 ohms anyway?

Well.  This is what my efforts for the past 10 days have reveald:  That my amp (an older RF 800a2) being a two channel amp is "happiest" at 4 Ohm's bridged.  This information I obtained from RF's online knowledgebases.  The only way I can think of getting good power to a single 10" sub at 4 ohms is to do it with a 2+2 ohm DVC.  The next problem that I am encountering is the enclosure limitation.  The Eclipse needs more breathing room than I have to give (1.25???)  I need a sub that will be happy in a smaller enclosure = .76 cubic feet.   I suppose a 4+4 ohm sub can be wired to 8 Ohms...but I have no clue how that will sound.  I dont think my RF amp can be bridged to 2 ohms as I have heard (and it says so on the RF knowledge base) that the amp will overheat. 

To respond to the comment about listening to the other subs...well that is just an impossibility for me considering where I live.  Here is CT, there are only a handfull of local shops, and most of them dont carry JBL or Nakamichi.  Only one shop carries Eclipse, and he only has 12's on the shelf. 

I guess I just dont understand wiring and bridging well enough...which is why I'm here asking questions.

as far as the impedences of the sub they were thinking maybe a single 4ohm vc instead of the dual 2ohms

sunshine was suggesting the use of a dual 2ohm sub because he needs the 4ohm load in mono. then he said he could use dual 4ohm for the mono in 8 ohm when people asked y he wanted to use the dual 2ohm just trying to make clear y they asked y he wanted the dual 2 ohm

A dual 2 ohm sub would be beneficial to someone using a multiple-speaker arrangement and want to present a different load on the amp than multiple 4 ohm speakers would provide.  The same is true for dual 4 ohm speakers.  Look at this Rockford site for a good wiring tool  http://www.rockfordfosgate.com/rftech/wiringwizard.asp

You are using one sub at 4 ohms.  It will be bridged at 4 ohms.  You don't need to limit your search to dual-voice coil subs.  I'm sure some other speaker suggestions are forthcoming, but if you can't hear...then I guess you'll be making a judgement on the merits of the testimonial.  (gregfocker wants to sell you his)

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Yes I want to sell them but they would work with what he has you can wire both subs and present 4ohm load to the amp like he wants.

And the sub will work with that box.....I have spec. sheet to prove it........

So, how would one of these subs mentioned sound at 8 ohms?  How much power will the sub see at 8 Ohms?
