Please excuse my car audio ignorance, but I was wondering if you guys are just not hooking up anything to these? Is there a way to bridge the rears for a small sub or use both channels on one DVC speaker? What are some of the popular easy options? can you fit two speakers in the door with the custom MDF plates made by the guy on this board?
Aftermarket stereo rear channel uses?

You shouldn't hook a DVC speaker to two different channels, bad for the speaker. I think most people are happy with just the front channels and a sub, although I have seen one guy that had custom rear speakers installed.
Are you saying they use the rear channels of the receiver to drive a small sub? If you have the Front and Rear of the same side going to the same DVC speaker, shouldn't it be like the same signal? Would a 6x9 fit in the door with a custom plate?
Yes your right as long as they are the same signal and wired in phase it could be done. Dont' think you would have enough power out of a head unit to drive a sub.
What I was saying is that most people add an external amp, I have a four channel amp, with two channels running the left and right fronts and the other two channels bridged to run the sub. Since the cabin is small and there are no rear passengers I don't think the rear fill is needed as much. If there was a stock rear location for speakers I would think about it, but for me, I don't think its worth the money to custom fabricate some speaker mounts for rears. As for the 6X9 I would think its a tight fit and I am not sure if you would have the depth required for the basket and magnet.
You might get more replies if you specify what you are trying to achieve. If you want a sub, the best location is in the passenger footwell. If you want some back fill, that's another issue.
Personally, I use the center channel (running off the head unit) for back fill. I have a switch that turns it on or off. I have upgraded the door speakers and have a toolbox sub in the passenger footwell plus amps to run all that stuff.
The amount of backfill volume coming from the head unit and the little BOSE speaker in the center channel is enough. I turn it off when driving alone, but when a passenger is present, I use the center channel. It seems to help with balance of sound that is blocked when a passenger is in the car.
That being said, the center channel does screw with the imaging from an audiophile perspective. Plenty of people on this forum would poo-poo the idea of additional speakers in the NSX. Personally, I find the center channel worth having - especially when you can flip a switch to turn it off.

Thanks Shaun, that sounds like a great idea, or maybe just use the center channel speaker for a mounting spot for two independant tweeters so you maintain some more imaging. I have no idea how the NSX is wired so thats why I am more ignorant. Here is my plan:
7" 3rd party GPS/reverse cam screen in nav pod, kenwood reverse tilt DVD 7" screen in center console (w/nav voice input to make install seemless). I want to use all 4 channels coming out of the kenwood. I just don't know if people are using a harness or just manually running speaker wire to their new setup and passing the factory wires (which were ment to carry a low voltage signal, not a powered setup for speakers). Can you shed some light on this? I like the idea of running some wire to the center channel and putting two little tweeters back there. My factory system is trashed anyways so might as well rip it all out.
Putting tweeters in the rear center channel will more than likely ruin your imaging.
Maybe a small mono woofer in there? Maybe a 6x9 rear facing sub in a rigged up enclosure? (yeah, ive seen a company make a 6x9 sub - weird)
I don't know if you have the room, a sub might be ok, as it will be lower frequencies but since its small, I suspect it will still be putting out higher bass frequencies and ruining your imaging. I would consider listening to others stereos in your area. You may be surprised at how well two fronts and a sub in the footwell sounds, I was a fan of the rear fill in my integra but with the NSX, I don't miss it really.

The factory wires will handle power for most door speaker applications. I personally ran new wires because I run a bi-amp system to the door mids and tweets. As noted above, you really shouldn't need a rear channels in the NSX. The cabin fills up with music and the simplicity of two channels helps imaging.
I would suggest running mono to the rear channel speaker in the console. I use the OEM head unit but you could as easily use use an aftermarket. And you could fade the rear channel out to a desired level. It's hard to believe, bur trust me......you will not want to put much rear volume in the total system. It's an ambiance thing....not something to use so as you can tell it's driving sound from the rear. As for me...I simply used the OEM amp that is wired to the rear channel so no need to connect extra wires.
Maybe I'm alone on this but having rear speaker does 100% add fill (in my mind) especially with the top off. I have tested it with the rear speakers off and with them on and I personally think it adds a little fill. I keep the gain really low but there is a difference.
So in an aftermarket HU, would I use the pre-outs to the rear center/amp then?
Yes, that should work. The OEM head outputs are considered preouts. I presume your head unit has separate preouts for the rear channel. If so, this is how you can fade the volume on the back fill. As Martini-1 noted, preferences vary. He had an interesting comment regarding topless driving. It certainly does change the overall sound of the system. It's your choice, but I'd suggest you start with the OEM speaker and if you like the backfill feature, you can always expand from there!
Are you putting an aftermarket sub in the footwell?
Of course it adds fill, its just bad for imaging, its just a matter of preference.
What is behind the rear speaker? Seems like there is a good amount of room, could it be a good place for a VERY good 3.5" sub. Yes, No? Maybe a sub deep in there ported out of that mesh?
Just thinking out loud.
