Is there any special reason that most nsx owners

[baynsac]

Is there any special reason that most nsx owners put the sub in the passenger foot space and not behind the seats?? Just wondering because I can fit 2 10's back there or one 10' or 12' sub in the foot space. I would like to know the advantages and disadvanatges for both.

Question #2 - Is Dynomat, should I do the doors only or should I do passenger and driver floor as well??
Question #3 - Can I do anything to protect the amps in the trunk from heat??
Question #4 - what alarm system has all these features??
- remote starter
- keyless entry door
- keyless trunk release
- back up siren
- 2 way paging

Thanks your time and opinions as ussual I believe prime owners have a lot of knowledge and I love knowing I can ask questions and get good answers before spending my hard earn money. I am only 22 and spent 10k on my stereo on my expedition and was barely satisfied with so many I should have I could have's. Going to do this right the first time with my NSX.

I'd like to hear other's opinions/experiences, but I've _heard_ that under the headliner makes a big difference to interior noise. I also wonder how that varies for coupes vs. Ts.

#1 Room behind the seat is so limited, not many subs would fit. I just received an Earthquake 10-SWS and I'm attempting to install it behind the driver seat. I currently have a JL sub in the passenger footwell and plan to compare sound.

The enclosure behind the seat is not much larger than Earthquake's minimum sealed enclosure recommendations, so I probably will loose some low end when compared to my current enclosure. However, if performance is acceptable, I'll look to build a second one for the passenger seat and removed the footwell enclosure.

Basically, I'm hoping that 2 10" subs (each located behind a seat) is equal or better than one JL 8W6 installed in a very good enclosure (toolbox) located in the footwell. If equal or better, I will be VERY happy with the outcome. Schedule is a bit busy, but I hope to have some results within a week.

My first attempt at a sub enclosure behind the driver's seat went pretty well. Using a Earthquake 10-SWS inside a MDF cabinet measuring approx. 14" x 14" x 3.5" I was able to comfortably fit it behind the driver's seat. The sub pounds against my back and overall it competes well with the JL 8W6 I had in the passenger footwell.

I need to take some time to readjust the frequencies as I hear too much high coming from behind the seat and it is messing up the sound stage. Also, lower freq. are also a bit absent due to the shallow sealed enclosure.

Still, I like the leg room in the passenger seat. Unfortunately, I could not convince myself that another enclosure behind the passenger seat would result in adequate leg room. When you push the passenger seat up to the same level as I have the driver seat, it is sort of tight due to how close the glove box comes up to the passenger. Still.......I'm hopeful that the results are satisfactory and will continue to play this idea out further.

Well, I've got four 10" woofers behind my seats and they rock Pics are located here. I'm a basshead so I went with four behind the seats vice one in the floor :biggrin:

I'm thinking that the logic behind NSXers putting woofers in the psgr side footwell is because the decrease in the footwell area doesn't affect the driver's side.

Here is someone that had two woofers behind the seats:

There has also been someone that has mounted a woofer between the seats:

Out of curiosity, how do subs that fire directly into the seat back keep from wearing on the rubber surrounds? I would think the speaker excursion would run right up to the seat covering.

For the small box I built behind the driver seat, I have the speaker pointing towards the firewall and spacers to create a 1" space between the cabinet and the wall so that the speaker is protected and allowed to "breathe". With a little EQ and LPF adjustment I think it will sound pretty good - but definitely nothing like the rear seat monsters you have posted. Those cabinets are unreal!
