As a person who has built on this motor and knows exactly how tight the gap is i would not recommend running them daily. These were built for the BURP vehicles in mind to give you huge motor strength but not anywhere near as forgiving as a standard XL. Remember all the Dc subs are build for reliable daily use, not so much peak SPL, this is where the new SPL versions come into play. Just remember that if you want a daily sub get the standard version.
