Today, I'd like to show you how to turn an old subwoofer box into a doggie playpen...

Step 1:

Remove your subwoofer enclosure from your car.

Step 2:

Chop the top.

Step 3:

Clean the inside, bracing points, stables, sharp edges and all. A dog's gonna live in there for christsakes!

^*Seal the port, if you have one!

Step 4:

A final dressing.

Step 5:

Insert love.

Voila! Now, you've just turned a useless sub-box into a wonderful home for your new pup! Until next time, enjoy!
