Best sub-100$ 15 inch subwoofer?

[Guest]

quality for sub hundred dollar subs will all generally be the same.

you said you want it theft proof by running 2 15's in a box that is big and hard to get out. and because i know prefab boxes are always on the small side (2 cubes for a 15), i would suggest doing a single sub setup like a vvx 15 or sa 15, but in a big box that is the same size as a dual 15 prefab. so the box will be 4 cubes for one 15 instead of 4 cubes for 2 15's . by doing this you will still have a "theft proof" set-up because of the big box. and you will also still have good output even though its one sub instead of two because your going up to a higher line of sub..
