I'm kind of new to car stereo and have a basic understanding but i easily get confused. I have 2 punch hx2's in a sealed box and I am powering them with a Kenwood KAC-9103d that puts out 900 rms x 1 at 2 ohms or 500 rms x 1 at 4 ohms. Since my subs are 4 ohms, are they each getting 500 rms or 250?

Are your subs dual 4 ohms? If so, you should wire your sub's voice coils in series and then the subs in parallel, this will net you 4 ohms (two ways to get 4 ohm load with these subs, both are fine) and deliver 250 watts to each sub. With those subs, you need a 1 ohm stable amp to get the most power out of the amp.

Ya they are dual 4 ohm

Wire the coils of each sub in parallel and then the subs in parallel with each other. The manufacturer's website claims the amp is 1 ohm stable which means this will get you the most power out of your amp. This would be most likely around 500 watts a sub.
If you wire them the way I mentioned in the other post you'd be at 250 watts a sub. I'd definately wire them the way I mentioned in this post seeing as the manufacturer claims 500 watts RMS on the 10' and 12" versions.

When I bought the subs this past weekend, they were already in the box and today I popped them out to see how they were wired and the box has a board between the two subs, so it is like they are each in their own box. So i cant wire them together

Yeah you can, just run the wire outside of the box. If everythings in parallel, run speaker wire to each sub and at the amp connect both positives to the positive and same with the negative.

Ya i guess i didnt think about that haha. So do as it says in wiring option 1?

Yup, that'd be the one.

Ok. And on my amp I have 2 positive and 2 negative speaker terminals, and you said to put both positive speaker wires into 1 positive and to do the same with the negative? Correct?
10-13-2009
Yeah, check on the amp, it should tell you where you hook up the positive and negative for using it bridged.

Ok thank you very much. I will try to get everything worked out tomorrow after school.
10-13-2009
Not a problem, lemme know how it goes.

So i got everything wired right and they are working, always a good sign but when i connected my speaker wire to my amp, it didnt say where to put them if i was bridging them so does it matter what positive and negative i used?
10-14-2009
I'd wire the positive wire to the most outside positve terminal and the negative wire to the most inner negative terminal.
