I Just got some of my pictures back from the pharmacy and here are some of my engine bay and home made sub woofer box

 

Nice job on the subs. I did a similar job about 10 years back on my first rex. I went one step further. I custom cut expanded steel grates for the top of the speakers to protect them and covered the whole back with carpet. You couldn't see any sign of the woofs... but you could definitely feel them

 

I would really appreciate it if you would post some bigger pictures...from here it looks good but hard to say.
