Sundown X-15 full build for my 1990 Nissan 300ZX. Lots of pics.

Hey guys, fellow basshead here. My name is Zach, I'm 18 and I live in Sacramento, CA (home of the legendary Steve Meade). I wanted to show off my build a little bit, as well as get some criticism from you guys. Over the past 6 months or so I have been creating my first real, complete build on my own. I am kind of an intermediate when it comes to box building, and I have never built a box this large and custom, so the finished product isn't perfect, but I am really proud of it.

Alright so a while back I had my license suspended for a few months (too many speeding tickets). Throughout the suspension I bought a new Sundown X15, I knew how beastly the sub was and I had never owned a 15, or any sub that had cost me over 100$. When I bought it I had intended to put it into my 2007 Nissan Sentra. Before I started building, I ended up finding a really good deal on an old 1990 Nissan 300zx and decided to buy it. I loved the car but I mainly bought it because it was half as much to insure the 300ZX than it was to insure my Sentra, due to my record being fucked up from speeding. So I decided to put my new Sundown 15 into the 300ZX. As some of you may know, the car is a 2 seater, and right behind the seats is the trunk, and there is very little trunk space to work with back there, especially for a sub of this size. But I was determined to figure something out.

My full system:

Sundown X-15 V.2 D2

Rockford Fosgate R1200-1D (I am upgrading the amp next month)

2 Optima Deep Cycle AGM Yellow Top Batteries

180 Amp aftermarket alternator

Sony MEX-N5100BT Stereo

2 Boston 6.5 inch Speakers

2 Soundstream Tarantula 6x9 Speakers

Stinger 4 Gauge OFC power wire

Harmony Audio 0 Gauge CCA for ground

Sky High Car Audio 8 Gauge OFC Speaker wire

Check it out, tell me what you think:

The Sub

Tiny Trunk with some leather material laid out.

Started building

Progress pic, after some fiberglass resin

Finished building then wrapped it in a nice material

Alright so here's where I realized I fucked up and measured wrong, and making the box too big to fit into the car.

Yeah, oops.

I then made a small adjustment on the box to fit it properly

It Fit!

Perfect.

Here's the amp on a little rack I built really quick. I know the amp is too small and weak for the sub, I bought it before the sub. Im upgrading my amp next month to either a Sundown SVC-2000D or the Crescendo 2200. If you have other amp suggestions let me know because I'm shopping around for one.

The new 180amp Alternator

Optima Battery in the trunk. I don't have a pic of the one under the hood, and it's dark out so I don't really feel like trying to get one at the moment.

I replaced the blown alpine 6.5 inch speakers that were in the back with 2 Soundstream 6x9s (I know it doesn't look great)

So that's all of it. I am still updating constantly, making stuff look better, upgrading equiptment. The next thing on the list is a new amplifier. Let me know some amp suggestions, the sub is rated 1500 watts rms but can handle way more. I'm considering the Sundown 2000 and the Crescendo 2200.

Thanks for checking it out guys! I'm really proud of this build.

I was wondering how you were gonna get that sub fit.

I love those cars, good choice of sub and current sub amp. I'm surprised you got an alt for that car, lol

Any work done to the motor?

Looking good BTW

No known work done to the motor. I was also surprised that I found an alternator for it, but I could tell I was causing damage to the one that was in there so I had to get a new one.

Looks good. But PLEASE find a way to secure the enclosure.
