Subs ?

I have a single cab 99 Tacoma and I Was wondering what kind of box do I need in order to fit in here without adjusting the seat or remove my emergency tire changing kit ? I've found a subbox that is specially molded to fit around all of that and allow my seat to be all the way back but it's around $500 and that money I don't want to invest in getting subs. I was planing on building a box but I wanted to see what you guys have out there that I haven't seen

 

Try MrMarv on here, he does custom stuff and might have a better price.

I had split boxes in my 2010 when I first got it but upgraded to the molded type you mention
