Stock 80a rewound to ~120a. Nothing special. Keeps up though. Never go under 11.5.
New port too, still haven't installed t-nuts. Audibly louder. Sounds even more so amazing down low, even though I'm tuned higher. I think it made a huge difference going external with the porting too.
Old one has all the screws in it (6x6x10, made tuning ~45hz), new one is on top (7x7x10, makes tuning ~52 IIRC)
