So I have this amp already:

And it has

4 ohms: 150 watts x 2 chan.
Bridged, 3 ohms: 300 watts x 1 chan.

I want to run a 10" sub, this seems to fit my price range and seems very good for the $:

Now, with that amp, Do I want to run a DVC or SVC? Neither seems to get me to my goal of 3ohms. From what little I know, I want to match the amp and sub impedance. I will likely be running it in a rrq box like this: http://cgi.ebay.com/ws/eBayISAPI.dll...:X:RTQ:US:1123 Thanks!

 

that amp will produce 300 watts - with impedence (ohms) from 1.5 to 4)

I would do a DVC - wired parrel, 2 ohm load.

 

alrighty, thats what ill do then

 

While I hate to contradict 2big4 who certainly knows his stuff, it looks like in
bridged mode that amp produces 300 watts from 3-8 ohms, rather than the 1.5-4 ohm
rating unbridged (150w per channel x2) mode.
Looks like that DVC sub can be wired 2 ohms (parallel) or 8 ohms (series). Parallel
will bring the impedance below JL's rating, but in series at 8-ohm you'll still get
the 300 watts. With most amps you'll get the most power out of them at the lowest
rated impedance, but those JLs have a regulated power supply which produces the same
power across their whole rated impedance range.

 

you are correct, if it wont do the 1.5 then do SVC (4ohm)

 

you are correct, if it wont do the 1.5 then do SVC (4ohm)

 

So I want to go with the SVC or the DVC in series? Just want to confirm. Appreciate the responses!

 

If you will always be running with that amp, I believe it doesn't matter -
the amp produces 300 watts for any impedance from 3-8 ohms.
4 ohms (SVC in this case) is the most versatile, as virtually any amp is
4-ohm stable, even when bridged. But if you went with a dedicated mono
sub amp, most of which are 2-ohm stable (some multichannel amps are 2-ohm
stable when bridged also) and don't use a regulated power supply like the JL,
you'll likely get more power at 2-ohms (DVC in parallel).

 

Sounds like I'll just get the DVC and wire it in series, for the less than $10 it will cost and be better for the future (I use subs very gently). This thread has been great, I had no idea the JL's were regulated (it was in a car I bought, then I returned the car to stock when I sold it, so I didn't do the research I would normally do when purchasing).
