Our first 370Z build.

Nice. So the 3" mids will fit in the factory tweeter location, cool. What are the crossover points please? Is the tweeter mounted in the pillar next to the mid location?

John

Jeff Smith

The HL70 requires a lil modification to the dash. Nothing major. The tweets are about 1 " above the mids. The X-over points are:

Tweet 4.5K
Midrange 450hz-4.5K
Midbass 450hz-40hz
Subs 50hz

Kenwood DNX8120 has EQ and time correction in it. The car images and stages like crazy!

Thanks! Would I be correct the dash mod you speak of is under the factory grill, and not visible once the grill is re-installed?

John

Jeff Smith

Yes the mod is under the grill. There are 4 alignment tabs for the 2.5" square speaker and the opening for the speaker has to be enlarged. We wrapped the pillar and dash grill in black grill cloth so that they blend in like factory.

Jeff, as the custom install manager, what do you think about a custom enclosure that will fit inside the spare tire itself, for those of us that don't want to remove the spare. Something that would fit an 8" or 10" sub like the new slimline Pioneer series?

John

Jeff Smith

I personally think that the better choice is going to be removing the foam in the cavity just in front of the spare tire below the strut bar and installing a JL 6W3 ported in that location. It will rock the house! I just need another local car here to test this in. There is enough roon there to install amp and sub. Without going need the spare at all!

Now this I am very interested in! Being able to keep the spare AND have a stealth sub setup so I don't loose trunk space. Please keep us informed when you have tackled this project.

John

37Z

I am considering locating a pair of sub and a small amp in the location you mention above. I interested in the size of the JL 6" of 8" sub box(s) needed whether down firing or ported.

I do not understand this explanation, can you expand please.

What do you mean that the tweets are 1" above the mids???? I am a little lost....sorry.

Could the factory tweeter covers have been left without the added grillcloth and still look stock, no modifications needed to the covers? And could the pillers have been left stock with no cloth wrap as well, just a small grill cover for the tweeter? Thanks.

John

Jeff Smith

Yes the grill cloth could have been left off but the aesthetics of the car from stock made the grill cloth blend so much better. If you look at the roof of your car it's dark grey/charcoal grill cloth style headliner material. The factory plastic is black so it just made sense to add the grill cloth. Seeing speakers to me is uncalled for. I don't like for people to know where the sound is coming from but for them listen with their ears and not their eyes. I've been doing car audio since 1990 and judging and competing since 1993. The easiest way to teach someone about soundstage and imaging is to get them into a car where you cant see any speakers and ask them where the sound is coming from and to explain the sound of what they hear....As in depth, ambience, focus of what they hear.

I haven't seen this model of a Kenwood HU in some time. Was it used? How well does the 8120 work for imaging the sound? Is their any comparable Kenwood HU with EQ and time correction in their current model line up?

srr2449

No the head unit was brand new. The sound imaging is great, and I am not sure if there is another comparable Kenwood HU in the current line up because I haven't looked or followed it since my install.
