yeah its easy enough to make one bit of trial and error or get a large sheet of card to try out with
basically cut around your own parcel shelf and see if it fits if it does trace it onto the mdf

only difference between your own one and a proper stealth one is that if you make it yourself is that your own one is flat the proper shop ones are normally matched to your standard shelf ie dips and raises are matched
and usually they only have cut outs for 2 6x9 if you want more its a lot harder to find one


should have said when fitting the speakers use countersunk bolts, 5mm usually are the proper size but can be hard to find otherwise use 6mm and drill out the screw holes a bit and bolt underneath that way when youve put the mesh and carpet on there is no giveaway bolts or raises

if you think you will be burning the speakers out or thinking you may upgrade the speakers put the countersunk bolt though and fit a nylock nut to the underrside and tighten up then speaker and then another nylock. using nylocks (nut with a ring of nylon, couple of pence dearer than normal nuts. my local ironmonger charges 4p for a 6mm nylock compared to 3p for a standard 6mm nut) will mean that the nuts dont come loose with the vibration from the speakers, plus if you lock the first nut up against the mdf it should stay locked so when changing the speakers only the bottom nut will need to be loosened and tightened up ( save having to remove the carpet to put an allen key in the bolt to tightened up the nut )


mesh or tightly pulled carpet, under the main carpet, is essential, if you dont there is the chance if you sit anything on the shelf over the holes the top carpet will stretch and show where the speakers are or worst case it damages the speaker cone



another piece of advise is not to fit the strings/ elastic to the mdf shelf, fit the catches that hold the shelf in place if you can get them off the original

fitting the string / elastic to a heavier shelf means the boot might shut on you, hitting on the head (talking from personal experience) elastic on the other hand will snap and drop the shelf
