AM is right that your amp must be up to the task of delivering more bass (ie power, current as needed) otherwise an equalizer will not help.
Its all relative though so sometimes cuts in other frequencies can produce results better than a boost in the ones of interest.
Like most things, it all depends.
One thing that always works to maximize bass is make sure your amp is capable of driving teh speakers to the max possible, not just to some minimum or slightly higher level.
Then, make sure your speaker placement and listening position is tuned as well.
After these two things first, then an equalizer becomes a decent option if needed.
And of course, speakers must be connected properly in phase or bass suffers.
