Dumb newbie stock speaker question

[soloracer951]

I bought a Zee V3 sub & box plus a set of Focal 165K2P components and will probably power everything with my old PG Route 66 amplifier.

It was my belief that the stock NSX stereo consisted of a pair of door speakers only. However, I just noticed the speaker grill between the back seats. Is this where the stock sub is that I hear mentioned? I read about it before but didn't know where it was and assumed that the stock sub was installed under the passenger floor mat and when I looked there and didn't see one I thought that my car didn't come with one. Now that I see the center grill I'm thinking that is where the sub must be because that would be a really odd place to put speakers for rear fill purposes.

In your stereo installs has anyone put in rear fill units or is it all door speakers and sub only? Can you confirm what is behind the grill on a stock car?

On my 92' the sub is in the passenger footwell behind a metal plate. There is also a speaker between the seats and 2 door speakers. All speakers have their own separate amp, except for the speaker between the seats, it shares the sub footwell amp. (not sure if it's considered a sub as well or not).
I've only had my car a month, so I'm not an expert yet but I currently have all of the speakers out for amp repair.

If I'm not mistaken that area in the rear center between the seats is a speaker that acts as a center channel that is powered by the amplifier in the subwoofer,located in the passenger footwell.

As far as that location is concerned when I did my install I actually just left that speaker in there in case I ever wanted to retort back to stock. I did have the thought of making a template to install tweeters but its not really worth it because if they arent with in a certain proximity to your componets it wont make sound properly.

With templates for the doors you can PM decosse or zetoolman. Both of them offer speaker templates for your doors.

Good luck on your install!

the stock "sub" is under the passenger footwell (dig for it!) and "tweeter" is in between the seats. The amp is crossed over so the speakers get the appropriate frequency for their size.

The sub and door speakers are 1.0 ohm. The center speaker "tweeter" is 4 ohm as it doubled duty for the hands free OEM cell phone

Did all NSX's come with stock subwoofers? The reason I ask is my evaporator got plugged and flooded my floor which required me to pull the carpets and dry everything out. I don't recall seeing a speaker in the passenger footwell.

I already have the z-man speaker mounts. I just have to enlarge the hole a little bit to fit the Focals.

It's interesting that the factory put a rear center channel. What is the logic in that? Has anyone disconnected it just to see how the stock system sounds without it? Was the difference noticeable?

In regards to aftermarket component placement, how did you guys position the speakers? Pictures of various set ups would be appreciated. I've had kicks done before but found that with a passenger I lost a lot of the high frequencies. I also used the mounts up by the mirrors and I see the NSX has a nice triangle cover there but most of the intalls there seemed tacked on rather than integral to the interior. I would rather recreate the shape, mount the tweeter inside and then cover the entire thing with grill cloth. Anyone done that before? Or do most people mount the tweeters next to the driver in the door? Opinions?

Behind the grill between the seats is the 2" center channel speaker, nothing else. The center channel (between the seats) isn't the same as a tweeter, to my knowledge, and is there just to provide some "fill" to the sound. Many people have a lot of experience with how the stereo system sounds without the center channel, as the center channel usually fails. (In fact, all of the various components usually fail.) Many of the aftermarket installations which are done seem to leave out the center channel. If tweeters are installed they are usually installed in the doors.

All NSXes came factory with a subwoofer located underneath the carpet in the forward passenger floorboard (not the flat portion of the floorboard but the forward slanted portion of the floorboard on the passenger side).

The overarching criticisms of the oem stereo system is that it is unnecessarily complex (preamp head unit with too many separate amplifier assemblies to fail) and that the oem components are unique to the car, necessitating serious modification to allow installation of aftermarket equipment with modern features (DVD, NAV, satellite radio input, mp3 player input, etc) when the original starts to fail. (New oem components are also extraordinarily expensive.)

Attached is a pic of the oem NSX subwoofer (located in the passenger floorboard) and oem speaker assemblies (located in the doors). The subwoofer and speakers, which each contain an amplifier since the oem headunit is a preamp unit, can be electronically rebuilt, if necessary. I believe that rebuilding the sub/amp will restore the center channel speaker unless the speaker itself is fried.

In my opinion, it is better to have the original components repaired than to attempt a complete stereo replacement. Since all the NSX components are essentially unique to the car, you can't just pull out the old components and bolt in new replacements. So unless you are extraordinarily committed to spending the many hours required to research, design, and install a new system, or unless you are willing to have the stereo replaced with an "open wallet" approach, you are better off by keeping the oem bose system. Having said that, there are a few owners who have shown the committment necessary to achieve outstanding results in their custom installations.

{edited}........In my opinion, ...........

do you mean "in my opinion"? or in your "emotion"? just asking.

Have you tried to install an aftermarker HU yourself to justify your statement? I mean to say that you are a researcher that does not like to speculate.

The hardest part about installing an aftermarket radio is overcoming the center console issue- this being the odd shape of the area for the tape deck and radio.

Ouch! I thought about you when I typed the word "opinion". I actually paused and thought, okay, is the word opinion being used correctly here? Since I did the removal and installation of my speaker and subs, and since I am two thirds of the way through a stereo upgrade, (XM and Ipod added, but not a head unit replacement) I deemed it reasonable to call it an opinion since it is derived not from how I feel about it but from actual hands-on experience. But I did analyze my own use of the word "opinion" before I typed it.

I agree - this is the concensus opinion.

I've come to learn that the hardest part about installing an aftermarket radio is making the final decision as to what you're gonna do. So many people think they will be satisfied with the stock speakers then end up adding an amp and replacing the speakers with components thinking they can leave out the sub. So then they end up buying a sub and decide that it would be nice to have navigation, and then an extra monitor. Then they want a backup camera and bluetooth.

It usually starts with a desire to integrate their Ipod and it's all downhill from there...

Have you been reading my mind? I'm not even done with my Ipod addition and I have already been thinking, Gee, maybe I could get one of those carbon fiber center console covers with the double din opening and install one of those cool double-din head units, then replace the blose speakers, and restore the center channel, and replace the sub, and...

Stated opinions are really supposed to be "informed opinions".

The single channel center system is not that hard to deal with if you get the appropriate crossovers and mixers.

I am using the "Open Wallet" approach, Lol:smile:

I think the best thing to do is have patience, take your time, do a lot of research and then start accumulating the pieces necessary. Then while you are doing the install, take care of any preventative or maintenence items such as CCU, Window regulators, etc.

good info here, i was wondering how many speakers were in the nsx

thx for this thread
