Let me start by saying; as I post this... I am already changing things on the install.
But, that will probably be a never-ending venture; so here's where I'm at so far:
First off, the install subject: BMW X6-M
• 570 horsepower
• Twin-turbocharged 4.4 litre V8
• Zero to 60 in 3.8 seconds
• Will pull a full G in the corners
This thing is an absolute monster...
There are some really nice professional installs posted, and I admire the level of detail put into these.
But, I am just some dude in his (dimly lit) garage, working with everyday tools.
The cuts aren't fancy. There's no 3D printing. And most of the material came from Home Depot or Amazon.
The equipment is all the same as what I had in my previous vehicle:
OEM Head Unit into mObridge DA3 into Helix DSP-Pro Mk II
Amplification: MMATS HiFi-6150D and MMATS HiFi-4250D
Front Stage: Sinfoni Tempo 10, Dynaudio Esotar 430, Audio-Development W800-NEO
Rear Fill: Audiofrog GB10, Audiofrog GB40, Audiofrog GB410 (passive crossover)
Subwoofer: Audiofrog GB10D2
As with all my installs, I have two basic criteria:
1. Sound Quality
2. Stealth Installation
Let's start with the install location. Under the rear floor is a hidden cargo hatch, with a fair bit of room:
With the carpeted floor removed, we have a lot of room to work with:
Covered the floor with sound deadener, and also up the sides (did the sides later in the process):
Next, it's time to cut some 3/4" MDF, to make the sub enclosure and amp rack:
Construction adhesive and brad nails... this thing will never come apart:
Audiofrog specs 0.6 cu.ft. for a sealed enclosure on this sub. My enclosure nets 0.67 cu.ft. after the displacement of the sub.
Test fit, with the bottom layer of the amp rack added:
