I am basically satisfied with the main gear I have but will continue to do minor upgrades. My wife has come to accept the 5 cu ft speakers are staying, but I really want subs now as the original 15's that are in there are of old skool design and were never made to play deep down. That will probably be the last thing I address but with so many many different opinions, and the costs of getting heavy subs here, it will be a while before I can add this piece to it. In the mean time, I mostly enjoy the hell out of my rig, with the exception of the lowest 100hz.I just try not to focus on its shortcomings.
