I run a soundstream lil wonder 5.830 .
specs- in 4 ohm stereo - 4 x 75 + 1 x 180
in 2 ohm stereo - 4 x 140 + 1 x 270
in 4 ohm bridged - 2 x 280 + 1 x 270

not one ohm stable

In the past I ran an o2 audio 10" 4 ohm dvc sub using both the bridgable channels to the one sub. I just matched the gain as close as I could. I believe that gave me a 2 0hm load, max for the amp.

I would like to run 2 - 4ohm dvc 12" -- one on each of the bridgable channels.
heres what I need to know.
When the amp is bridged does that mean you start with a two ohm load at the amp regardless of the sub?
If it is 2 ohm, and then I wire a 8 ohm load(the 4ohm dvc) what is the amps load? Or can this even be done?

I guess what I really need to know is, how CAN I wire the 2 - 4ohm dvc subs to the two bridgable channels, and what the final load will be.
I apoligize for the novice attempt of explanation..
peace

 

The amp's load is determined by the speaker's impedance (ohms), so if you put 2- 4ohm speakers on the amp it will deliver 280 watts to each in bridged mode. Your amp is rated for 4ohms in bridged mode, therefore your dual 4ohm subs can not be safely run (if wired parallel to 2ohms) on the bridged channels. If you want, you can wire the voice coils in series for an 8 ohm load, but you will get about 140 watts to each sub (power is halved as load is doubled). If you haven't bought the subs yet, you can get dual 2 ohm versions (if available) and wire them to a 4ohm final load each and hook up to the amp. Otherwise you need to find a 1ohm stable mono amp, or 2 ohm stable stereo amp for your subs.

 

Yeah, I have the 2 12"s already, I was running one for the last year on a clarion at 4 ohm mono( i think) and just bought another because it matched. All done before I really understood the wiring/load idea very well( or had the chart at jl audio!! )

Sounds like a new amp would be the only real option to make the most of the subs. Thanks for the reply.
My current budget has only enough for new (much wanted) 6 1/2 components OR a class d mono amp . Can't afford both so I'm trying to figure out the how to run the 3 - 4 ohm dvc I have on the soundstream properly and get good bass.
Then I could run the new components on the clarion 2 x 100 @ 4ohm


Perhaps you could explain this to me; from the manual of the LW

" when utilizing the 5th channel mode,please use a specified inductor(blocking coil) in series with the 5th channel(sub).In order to prevent frequency overload and distortion issues?"

What does that mean? another crossover to use a sub channel???
I gotta have that wrong!!

Any idea?

 

yeah, apparently there is no electronic x over built in to the amp, so to restrict the frequencies sent to the sub, you can use a passive x-over (inductor coil) which only allows frequencies below the cut off point to be sent to the sub. If your head unit has a sub x over built in or you have an outboard electronic x over, then you wouldn't need that. That's an older amp and back in the day when those came out amps rarely had anything extra like x-overs, eq's etc... built in.

 

Thanks. I was hoping it was something that easy, I have a soundstream digi-q with sub outs.
Thanks alot Denonite.

 

No problem bro
