R34 12" Sub Install

[Addicted2BoostR34]

hey guys i have been trying to work out the best wat to install my 12"fosgate sub in my 34

i have been looking at the ebay fiberglass ones but i not sure on the sound guality it would put out

i would like it so i can still use my spare wheel if needed but have it so i can do some spirited driving and not have to think about damageing it

any pics of what u have done would be nice cheers

here is a pic of my old sub box with new sub n paired amp i was thinking redoing the floor in chip board and haveing some mounting plates that wing nut it down to the spare wheel cover and mount the cover/ floor to the body same way soem f*kn around to get spare wheel out but atlast i could and my box wont move ?

I did the same moulded sub enclosure, sounded great, but I had to pour like 4L of sound deadening into it, add dacron as well as make a small bracket and wrap the underside in anti-slip matts.

It did not move at all

mount the amp under the rear shelf, on a wooden baffle, either on show or behind the wood so you can't see it

mount the sub in a custom box on the passenger side , where the jack is. mold a box to fit the space, move the jack to the middle of the spare tyre.

all can be hidden and spare comes out without any other mods. nice tight bass, .

eblow box, works but takes up too much space and sounds generic

. you can fit the sub behind the factory panel if you do a custom box. and add another on the drivers side if you desire later. or mount the amp behind the rear panel on the drivers side , totally hidden !!! no metal cutting /mods to mount it

if you look behind the trim panel, where the jack is at, the space is just right to fit a 12" sub in a fiberglass box. you can use the little tabs on the metal to mount it. and if desired remove it for track days.

it can fit completely behind the factory panel and a custom grill made to hide it. or show it off your choice. I had mine there but now use a bandpass box which uses that area and some of the space outside the panel, ported thru the rear deck holes. the space is deep enough for most subs and if they work in a sealed box your all good. which the rockfords do

not sure if I still have any old photos , but can show you a photo of the size hole when removed.

You could probably replace the thin floorboard into a much thicker one, then use bolted down heavy duty straps to hold your sub+enclosure+amp in place, it will never move. And you can still access your spare wheel in case of an emergency (pssst, or carry one or more of those fix-a-flat cans) That is what I would do anyway.

it will move, when you drive spirited or get hit it turns into a missle.

example

on a defensive driving track day in my work car, a 1.5 litre half empty water bottle in my camry boot , tore the folding rear seats down while latched while on the ABS brake thru the cones test. now imagine a box, amp, speaker, hunk of wood, ripping the rear plate open on the r34 and landing on your lap or the side of the car open like a can opener.

I'll dig up some photos today.
