Hey guys,
I have an Orion CS150.2 Amplifier and I have two Orion Cobalt DVC 10" subs for 2002 in the mail from ebay. They are coming this week and I wanna know how to wire them for most efficient power. The amp is two channel and its power ratings are as follows:

- 90 Watts x 2 @ 4 Ohms
- 140 Watts x 2 @ 2 Ohms (??Wired in parallel??)
- 260 Watts x 1 @ 4 Ohms (Bridged)

Here's the subwoofers features and description:

- 200 Watts Nominal (RMS) power
- 400 Watts Maximum (Peak) power
- 10" Woofers
- Dual Voice Coils

Now my question is, how am I going to wire the subwoofers in parallel to get the 140 x 2 @ 2 ohms? Is it possible to wire the subs in parallel in bridged (260 x 1 @ 4 ohms) mode? If I do this will I make 520 x 1 @ 2 ohms? I probably put a lot of confusion into this message, but is 520 watts possible and how do I wire it? Let me know so I can fire this up when I get it. I hate my 8 inch bass tube! Thanks guys.

first off will your amp handle the bridged at 2 ohms? a lot of amps won't that is why I'm asking. if it doesn't I'd do the 2 channels and 2 ohms. by hooking up both + of one sub to one channel and both - to the - of the channel. and then do the same with the other sub

Okay that sounds simple enough. The amp owners manual doesn't say anything about running at bridged 2 ohm power, I guess it doesn't handle it. I though it would. What happens, does the amp blow out or something, why can't I do this?

Since the specs for a bridged config at 2 ohms is not given then the amp is probably not stable bridged @ 2 ohm. This doesn't mean that the amp will explode if you try it but it could mean that the amp will overheat and may be damaged if you try this. Hopefully some protection circuitry would prevent permanent damage. (Unfortunately, most amps that can handle 2 ohms or less in a bridged config are more expensive.)

I'm assuming that the subs have dual 4 ohm voice coils. This means you could wire the coils in series for 8 ohm per sub or wire them in parallel for 2 ohm per sub.

So, if you series the coils and parellel the subs you'd end up with one 4 ohm load and the amp would put out 260w (130w per sub).

Or, you could parallel the coils and NOT bridge the amp for two loads of 2 ohms and the amp would put out 280w (140 per sub). This seem like the best option for your amp.

How do you do this? Take a length of speaker wire and connect it to the left channel of the amp and connect it to sub #1 at the first coil (+ to +, - to -). Then take another length of speaker wire and connect it to the left channel of the amp and connect it to sub #1 at the second coil (+ to +, - to -). Now take two more legths of speaker wire and connect Sub #2 to the right channel of the amplifier in the same way.

Thank you belker, I found your input very informative and interesting!

did you read your subs owner manual? i know i can run my rockfords at 1 ohm...since they are DVC and so are yours im guessing you can do it too...but i dont know if your amp can handle it.

The owners manual only gives specifications for two ohms at the lowest, thanks anyway, my amp can't even handle two ohms bridged.
