ooo~ tempting

They are JL Audio 6W3 & they produce some good bass. The two JL Audio 6" have more bass than one 8", but less than one 10". These two are also very well hidden & not flashly.

great setup!, something that im sure sounds better then stock, all the power i need, dont need to make my ears bleed!

is there the option of 10in in the configuration?

I know an 8'' would fit in each space as well, but I'm not sure about a 10". I wanted to be able to have the seats recline all the way back if one wanted to instead of sitting straight up. The set-up I have is very nice & the sound is effen awesome. One would not be disappointed with the set-up I have & you also have to take into account that the Z does not have that much interior space.

where did you buy the subs and enclosures from? did you keep the stock fronts and head unit?

I bought all my stuff at Houston Car Stero is on Hilcroft b/w 59 & Westpark.

I replaces everything. My HU: Kenwood DNX9990HD, Speakers: Hertz Hi-Energy System HSK 165XL (2 way system), SW: 2 JL Audio 6W3 & Amp: JL Audio HD Series HD600/4

thanks Maclean..the install is just like my 350, right behind the seats. I don't know why Nissan changed it...but it is what it is...thanks again for replying.
I was looking at JL, are the Hertz much better?

No problem man..... The Hertz Hi-Energy are really good. My two JL 6' subs put out a good thump & of course I have full range of my EQ as well. I was also looking at Focal which are very good, but pricey. I can't not complain nor have any complaints on my set-up.

Great use of wasted space. wish i would have seen this first before going with a 10 and custom box.
