Pro Audio Installed by Koch Instruments * Lots of pics

[Nick675]

My NSX just got finished with a professional install and am sharing my pics for you all in case you have questions or need inspiration.

Here is the pics of the beautiful crossovers from the PPI 356CS

Components used:
Old School Rockford Fosgate 600a4 (built in 1998 before they started building crap; 848 watts RMS certificate)
Heavily modified Angus subwoofer encloser w/ SWS 10"
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360197740499Precision Power PPI 356CS 6.5" Component Speakers
Monstor 4 way RCA cable
Homebrew CarPC w/true 4volt preamp out

Why CarPC you ask??? Because I can do whatever I want and it is much better than any headunit IMHO. I have GPS, Video, Audio, HDD w/all my music, WIFI, ODB-II, etc. Bootup is 5 seconds.

First off I had to relocate my electronic power steering unit to a better location. Since my car is tracked as well (multi purpose vehichle) I chose to completely remove the entire SRS airbag system. I chose to relocate the EPS to the previous passenger airbag location

Next I wanted to modify Angus box to bottom mount the SWS 10" and also decrease enclosure by 1 inch.

Next up was the main wiring into the cabin and through the firewall into the trunk.

Templates of the Bose door speaker/amp combo was made. I decided not to use the entire template as you will see in the pictures. The template was then glassed to enclose the 6.5" speakers and painted primer gray.

Now the hard part... Getting the wiring into the door for the crossover and speaker, tweater wasn't easy. I decided to use the previously used Bose amp connection and use 2 wires to ouput for the tweeters and the bigger wire's (yellow/red line 12+ and black/gray dot) as the wires coming into the crossover from the amp. The passenger side was easy, but the driver side was a pain in the neck. Wiring is same on both sides... yellow and orange used for tweeter and yellow/red line and black/gray dot used for amplifier.

Tweeters were installed on top of dash. Probably best spot on the NSX for them.

Finally, here is my CarPc on my 2DIN custom machine.

Hope everyone enjoys all of this. I know I enjoy the beautiful sound!

Good Work.

Where was the amp mounted and also, what was behind the tweeters? Is it just the Ac Duct to feed the doors? I wanted to put my tweets there but could not muster the balls to cut in that spot.

any off axis issues with the tweeter and the woofer being 90* from each other? That usually has some messed up effects if you install them that way. I have it that way in my tundra right now and Im trying to figure out how to change it.

Nick,

can you post some daytime pics of the dash? I would like to see how you fit the carpc in there.

BTW, where in MD are you? I'm in MoCo.

Forgot about the amp photo. Posted it above.

As far as the tweeters. I am aware of it being off axis, I modified resistors to change sound to my liking. It might have sounded better in the door, but liked this position better. Especially with Targa off.

Ya know that is funny you mention that, my off axis set up sound tons better with the windows open. Most of the time in the NSX the top is off! You might be onto something with that set up! Congrats again on the fine set up!

thanks!

I still have to make a mold for the center console trim and make holes for my meters as well. Need to carpet the amp mount. I also am going to modify the center speaker to add a little more mid fill. I just love the sound.

As for your previous question on the vents... I pulled out the vent to the doors on both sides. There is plenty of room to mount. Even if your tweeter is 2-3 inches deep. I cut the leather with a razor first then used a 2" hole saw

Did you have to modify the door to fit the speaker baffle you made?

 

[TURBO2GO]

Nice work.

 

[Nick675]

No modification to door to fit the speaker baffle. Only modification was the door wiring at foot well on both sides. Wiring inside door was untouched.
