New Car Stereo Set-up
 

I have finally finished upgrading all my factory components. I went with the following....

Head Unit: Kenwood DNX9990HD
Speakers: Hertz Hi-Energy System HSK 165XL (2 way system)
SW: 2 JL Audio 6W3
Amp: JL Audio HD Series HD600/4

The Hertz speakers I didn't take pics of since they are in the door (6 1/2's) & the dashboard (1 1/8's)

Where did you get those boxes? Not sure if they would fit behind my seats, since I am 6'4" but very cool.

They were custom made boxes. You will not have any problems with this kind of box made for a 6'' subwoofer. I can have the driver/passenger seat slide all the way back & tilted all the way back w/o any problems. I wanted a subwoofer that can produce a good punch, but not have to advertise that I have speakers in the trunk. The two 6W3's & both boxes were $606 out the door at Houston Car Stereo.

To me having two 8'', 10'', or two 12'' would draw too much attention & would cause some rattling noise. I have been there & done that with two Rockford Fosgate DVC 15's about 15 yrs ago with a 1k watt mono amp. I have a sports car & what to keep things real on my end. If I wanted to rattle things, then I would have gotten a Escalade.

Nice! How do the two 6s sound?

The two 6's sound really good & JL Audio speakers hit hard. For the size of the speakers & the size of the boxes, I'm not going to throw rocks at them. The two 6's have more bass than one 8'', but less than one 10''. So two 6's are b/w one 8'' & one 10'' for bass. The JL Audio 6W3 produces more bass than the Kicker 6'' which I was looking at as well. The Kicker 6'' doesn't have as big of a magnet as the JL Audio 6W3. I would highly recommend the JL Audio 6W3's to anyone who doesn't want everybody & there mother to know, or see that they have subwoofers. The amp that I have (JL Audio HD600/4) is pushing 150 watts x 4 @ 4 ohms & is RMS to all my speakers which is very good. OH FYI....... I do not have any rear speakers....excluding the sub's.

I'm installing all my stuff right now. I unplugged the Bose sub and drove around for a day without it. Couldn't tell a difference.:shakes head:

WOW........ I would think you would be able to tell a difference. What are you going to install?

I'm mid way through installing the same Hertz Speakers and the Kenwood 9990. How do you like them?

The 2 6" JLs are an interesting idea, I picked up the 13.5" spare tire box used on the forum.

I also drove around without my Bose sub plugged in, I agree with Stewie, I didn't even miss it. I'm worried the 13.5 will be too much.

Man I saw your work...... WOW....EFFEN SWEET MAN. :tup: :tup: I thought about going with the Focal K2's to begin with, but was told that the Hertz Hi-Energy 6 1/2's produce a little more bass. So I went with the Hertz. At the end of the day you cannot go wrong with Focal or Hertz.........well as long as you go with the right series.

The entire set-up is awesome. The Hertz speakers are great, but I do recommend playing around with the EQ (DO NOT LEAVE EQ ON FLAT). I have the speaker Dynamat for the 6 1/2 in the door. Thnxs.......the 2 6'' are nicely hidden & still produce a very good punch, but depends on how much punch (bass) you want. As stated before both 6'' are b/w one 8'' & one 10''.

WOW....... the 13.5'' is effen heavy & a huge effen woofer. You will need a very good 500 watt amp for it. I hope you do not have your car lowered b/c I will guarantee you that if you put the 13.5'' with box (obviously) that your car will drop. The 13.5" was meant to go into a truck, suv, or a sedan & not really a sports car.

I have not heard the Bose stereo in the Z, so I would not know how it sounds with & w/o the SW. I can say this I bet the Bose speakers sounds a lot better than the base speakers (factory speakers) that come in the base Z & in the Nismo. The 13.5'' might be too much, but I would Dynamat the hell out of the car especially the trunk for sure.

Oh FYI....... You can still put two 8'' where the two 6'' are at.

This is the passenger seat all the way back & the incline all the way back as well. The driver seat would be the same if you choose so. Once again behind each seat in the box is a 6'' JL Audio (6W3).

Congrats on the nismo!! Audio set up looks great. I got one 6" JL in the same spot. Just enough for an old guy like me.

I really like that set up. I just installed a Pioneer AVH-X5500BHS, but I had to get a dealer install my steering wheel controls. The dealer told me that he has built boxes to fill the compartment behind the trayed area behind the seats. I thought that would be a good option with sacrificing much space since I do not use them.

So you dont feel Dynamating the entire inside of the door is neccassary? Just the speaker surround?

just curious where you all ran your power wire to your amplifier from the battery? I cant find a good place to run it without tearing apart my dash . HELP!@

How to Run power wire to the rear hatch

Ill take the rep for that hard work. :happydance:

Aww ya beat me to it lol.

I love your setup man! That's exactly what I want to do. I do have a question about the subwoofer location behind the seats, do you have any annoying thumping or vibrations that come from the subs blasting behind your seat! It's a genius idea, but I'm wondering about the driveability of it. Is there a certain point when you drive that you just get annoyed at it lol!

I had my set up installed. The only Dynamating done was the speaker mounts in the doors. Man I'm not sure about the power wiring, but I did go with the JL Audio wiring. Thnxs for the props on the set up. I do not get any annoying vibrations from the subs. Of course if you turned the volume all the way up & on certain songs you will feel it for sure. I can adjust the EQ on the HU if I think the bass is too much. The HU volume goes to 38 or 40 (or more) which is the max for the volume. When you are at 12-14 for the volume there is no complaints. I usually have the volume anywhere from 10-14, but vary rarely go 16 plus. If you go into the high teens to low twenties, then driving for a length of time could get annoying (headache). The amp is 600 watts (150 x 4) and each of my speakers RMS is 150 watts, so I am not going to blow my speakers. Well I could if I was an idiot and put all the gains on the amp to 100%.
