Going from 2 DVC subs to 1 DVC

[Cris 10+ year member]

I have a rockford fosgate 551s ( http://www.rockfordfosgate.com/ez2/ModelInfo/ModelInfo.asp?ItemKey=10061234&CategoryDesc=Power%20Amplifiers)

and I've had it hooked up to two type R's (dvc 4ohm) wired parallel (resulting in a 2 ohm load per channel, 275 watts each sub).

Now, I'm getting rid of the Type-R's and installing one 12w6v2 sub. Here's where I'm confused on what to do. How does one hook up a two-channel amplifier to a DVC sub with only 1 speaker terminal?

To further add to the confusion, the amplifier does not list what it would output at 2 ohms bridged.. it only lists what it would push at 4 ohms bridged (550 watts). It makes me doubt that the amplifier would be stable bridged at 2 ohms. The problem is that I can only wire a 12w6v2 to either 2 ohms or 8 ohms.

If it was double the watts than 4 ohms, that would be 1100 watts.. which would be WAY too much for a 12w6v2.. and if I have to do 8 ohms, then that's 275 watts-- then that's 125 shy of what JL recommends.

Sooooooooo... anyone have any ideas???

not many companies make a/b amps that can handle a two ohm load bridged now a days. there are a few companies such as dls, zapco, older USamps lines, i also saw a couple of hifonics a/b amps that can handle a 2 ohm load.

i am also in the same boat as you in a sense that i am looking for an a/b amp that can handle a 2 ohm bridged. I've searched and searched and i've found a few but non in my price range. my advice is either add another sub or buy another amp. if you want to run just one sub then i would suggest sell your amp and buy another amp that run that w6 to its potential. i'm sure that the w6 can handle a lot.

time for a new amp //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

lol i'm a girl though, i won't do it unless the company states that it could. if you can say that maybe some of the newer amps can handle a 2 ohm load for my IDQ, you might have yourself another buyer //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif .

no im serious. YES!

 

[alphakenny1 10+ year member]

hmmm...just the md line?

 

[flakko 5,000+ posts]

depending on the sub, the IS line ( i will have to confirm with JR the sub before i have an abesolute answer)

 

[alphakenny1 10+ year member]

for the idq

 

[flakko 5,000+ posts]

kay ill pm you tomorrow with the answer k? how much watts you wanna throw at it?

 

[alphakenny1 10+ year member]

hmm well i'd prefer bout 300-400 watts so maybe the i/s 2080 since it'll do roughly 540 watts @ 2 ohm bridged according to my calcuations but i'll just watch the gains.

the IS 2080 wont do 540w haha. it will do around 300 ish i dont know if you drop the ohm load, the wattage will increase... i will have to ask that too //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

the IS 2150 will do 480w+

 

[alphakenny1 10+ year member]

eh 480 seems to be too much maybe yea whatever. just give some numbers tomorrow.
