H2 SUT Audio upgrades

[alpinetypers]

First off, I would like to say hi to everyone and I am excited to be the owner of an H2! I have owned it for about 3 weeks now and it is badass! I will post pics soon!

This topic is in regards to an H2 SUT.

I am wondering if there is any ways to get a more powerful Bose sub, or to replace the Bose sub with an aftermarket one?? Or has anyone ever seen or done a custom install that does not lose seating/legroom??

Pictures and "how to's" are greatly welcomed!
