bulkhead mounted bass
Discussion
I need some deep bass in my 2019 man tge (vw crafter rebadged)
my plan is as follows: standard vw discovery nav dab headunit into my pioneer 9604 amp as it has high level inputs and auto power switching, channels 1 and 2 with hpf into standard door speakers and some silentcoat in the doors as even with the standard headunit the doorcards rattle and resonate like hell, then a wide but shallow sub box mounted securely on the bulkhead above the driver/passengers head driven via lpf on channel 3/4. under the passenger seats is not an option as that space is fully used already with work stuff, and the load area is pretty full with racking, tools and stock as well.
Would this be viable, and if so should I build something myself using the full width and height available or just buy a kicker comprt prebuilt box with the 12" and a passive radiator?
I am looking for deep and tight and effortless, doesnt have to be too loud, looking for quality and depth over quantity
the sound I am looking to recreate is my home sound system of sonos hdmi amp, kef in wall speakers for the front channels, sonos play 1s for the rears and 2x svs pb2000 subs if anyone is familiar how they sound.
Any pointers? I have no problems at all with the practicalities of fabricating an enclosure, but I have never done any enclosure design and wouldn't know where to start as my free time is limited, trial and error doesn't suit, If I am doing something I would like to do it right once.
if it is any use I have a jbl ms8 lying around doing nothing, I stopped using it as it induced an echo in my trafics handsfree, and having to press the bypass button every time I taken a call was a pain in the hole as I get 30-40 calls a day, but if there was some way it could be used without ruining handsfree I'm all ears.

I was thinking along the lines of one of these https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2...
Unless building something would sound better
Space I am looking at:
Going to take the seats out and carpet the full bulkhead in 4 way stretch.
the ms8 is a brilliant bit of kit, its just the handsfree echo issue that lets it down. there is a custom firmware that turns the mute button into a bypass button to cancel the echo by switching off time alignment temporarily, but its an extra button to press twice every phonecall, And I have been enjoying having the handsfree solely through the steering wheel buttons.
In my trafic the ms8 was driving a 3 way active system, no passive crossovers, 8in midbass in the doors with mdf rings and a lot of deadening, 4 in mids in the dash tweeter positions and tweeters in the dash facing the driver next to the air vents, and a boxed 12 in the load area with the port trumpet extended through the bulkhead under the drivers seat.
Once it was tuned properly it sounded incredible.
I might punt it and put it towards my sub for the tge.

Extremely bad idea placing a sub above you as such
Even at low volume it will put a lot of pressure into your head
Also and I hope you don't find yourself in this situation
in the event of an accident you will cause yourself massive injuries
Lastly you will need to make it abundantly clear to your insurers what you are doing
under that increasingly used term Duty of care
Great results can be had going under the seats

Thats kind of what I was after. If I stary to get dizzy I might turn it down for a couole of minutes though, as long as it isnt something by bass generator, then I might be forced to soldier on at max volume. It will be higher than the metal roof in the low top variant, And I am more than capable of securing it, I plan to put 10-12 m8 bolts with penny washers through the sub box into the bulkhead then a steel spreader plate behind the bulkhead. I am experienced in fabricating, a lot of the stuff I fabricate at work is safety critical.
Insurance dont want to know the ins and outs, when I tried to tell them I was just told I didnt need to declare the sound system, but it wouldnt be covered in a claim. The call was recorded on my dashcam.

You completely missed what I was getting at
1-I have no doubt you are more than capable of doing the work
2- the pressure I refer too is not by listening to loud music it is frequency generated and causes a painful headache
3 -the damage that will cause in an accident would be like being hit round the head with a sledge hammer
4- in 30 odd years of professionally build audio systems I have never had a problem creating systems that rock
but never had to resort to putting a coffin by my head or anyone elses
still I wish you all the best
