I have an amazing design for a box for a cheap JL 12" sub (the 12w04 or something?).

I run it in my car and it fucking rocks.

I bought the design off a guy in the UK who's a demi-god at box design.

It's a 3 chamber, dual reflex, internally ported, sealed box. It is designed specifically for this sub.

It doesn't take up too much room either.

The sub it's designed for is only rated at 125w RMS, and my old Kicker amp (Impulse IX-702?) is rated at a similar power in bridged mono.

But fuck me it drops low and is tight as fuck (and loud too!).

If you can still get hold of one of these subs, then I can blast you over the design.
