Spare Tire Well Air Space...

ChopsZ · 08-31-2017, 10:59 PM

As the SI mids and tweets continue to break in, I continue to tweak the levels and crossover. In doing so, there's very little EQ going on. I still need to run the "Auto" T/A and EQ on the new drivers.

I gotta say, these speakers and this amp make for a very clean and clear sound. Though I still need a DSP to get the sound just where I want it. And even though there's zero rattles in the doors, I feel I can still do some tuning to fix that dip in the EQ at the doors with some acoustic treatments of some sorts. There's some kind of peak there that needs to be addressed. The less processing I can do without, the better I always say.

Oh, and the sub came in today. It's funny, I always used to think 15's were bigger than this. It's sitting on top of my JL e110 sub, which is a massive 10" driver. The Alpine doesn't look all that much bigger! It is a rather heavy, beefy driver though.

I had a sub enclosure made out of epoxy resin from some guys here in Austin. I have some pictures here:

Nissan 370Z Forum - dotcomee's Album: Custom sub enclosure/amp install

It sounds really good. It's not completely stock looking but still looks good I think.

Gotta love that big rear end on the Z, plenty of space for an enclosure.

Nice!

Yeah, with the big booty in these cars, there's quite a bit of available air space back there. I still need to figure out something for mine. I no longer have the tools nor the place to build an enclosure myself. That means I have to either have a friend or friend of a friend build it for me, OR find a decent shop that knows how to build quality enclosures to spec, both the driver's specs and MY specs.

The shop I went to to have the amp and speakers installed, they deal with another guy/shop to build custom enclosures for them when needed. Maybe I should talk to them again and see what they can do for me.

I wonder how much that would cost.

I took some more measurements today. If I were to build an enclosure to fit within the confines of those foam inserts on either side (just where the tire sits), at 19" x 20" x 8.5", that would only give me 1.3 cf of air space, so the foam will have to go. No real point of keeping it all there anyway if I'm not running a spare.

What I think I'll do is have the enclosure as large as possible, extending somewhat into the those rear corners. That will give me the opportunity to mount the sub off to the side towards one of those corners, probably on the passenger side.

It'll definitely be a little bit of a challenge to shoehorn this sub into the car, but I'll get it done one way or another.

As you can see in the pics below, this Type S 15 is a bit larger than the typical 12's installed in these cars... For obvious reasons.

I fabbed fiberglass boxes for my Del Sol and 350z in the parking lots of apartment complexes. =)

LOL I forgot you were local.

I hate fiberglass so much I would charge you more than a professional and do a worse job. =) The beauty of it is that it doesn't require much in terms of tools, etc. Just elbow grease.

The next box I fab will be for my own Z.... been hoping to avoid glass but I think it will end up that way anyway. Have an Alpine Type R 8" waiting to go in and looking to do my first ported enclosure.

Oh snap!

I didn't even notice the fiberglass part of your post. I was rushing on my lunch break and thought you just said "fabbed boxes for"... Didn't even see the fiberglass part. I wouldn't want a fiberglass enclosure anyway. Too much of a PITA.

Nah, for me, I just want to use good ole' MDF.
