Cool mate, yeah i started off the same, always about perfecting it isnt it?
I had a nightmare trying to block all the light and make sure the doors stayed tightly shut, but after many many nights starting over, i finally cracked it.
Now shes airtight, smell tight and heat tight and im stress free.
well, until now when i am building another one and my job is now been halted due to Crappy Mylar, they even folded it when they sent it to me ffs, coulda rolled it up at least eh? I dont know......
Think ill just stick with the diamond, oh well back on ebay lol
thats what i love about stealth cabs, If ya temps get too hot mate just cut a 4 inch hole at top and put a PC Fan Filter over it, lowers the Temp down Plus all the cold air coming in will force out the hot air at top.
