Yes, I have the 405x5 into 8 ohms. More power in reserve is always better, especially in light of how you prefer to listen. This amp won't strain no matter how hard you drive it - it will also work with other speakers you may decide to get further down the line(power doubles into 4 ohms, for example).
I am using the Reference sub ICs for my sub - pretty impressive after a relatively short break-in period.
