Smaller magnet is more efficient rare earth magnet... whole page about this earlier in the thread.

I missed that part of the thread so thanks for pointing it out. Not sure why they felt the size of the original magnet was an issue but that explains things. I am going to further explore upgrading with Focals and a new amp with speaker level inputs like the JL Audio RD400/4 along with the Taco Tunes wiring harness. That was my original direction. I could add a sub later if I think it needs more low end. Love the OEM A+ plug and play aspect, sub enclosure, and the amp mount but at 1700-2000 it needs to be great for me to feel that it is worth it. Hearing so many reviews that it is just improved but not great is not what I was hoping to hear.
I listen to classic rock, alt rock, country and bluegrass 90% of the time so I definitely don't need or want every one at a traffic signal hearing subs thumping in my truck. Just good clean sound with bass that has a solid punch is my goal. Plus space is a at a premium for me. Thanks for all the input.
