|First, don't use Winamp's small spectrum analyser to analyse your tracks. I admit this is one of the things that got me taking a step towards post-production years ago (was always wondering why in professional tracks the bars were always higher), but in terms of checking the frequency make-up, you really should use a real spectrum analyser.
This is because Winamp only shows movement of the bars whenever a sound in that frequency reaches above -30 dB or so (or close enough anyway). Something you may not understand at this stage, but just take my word for it that you shouldn't use it, as it's only really a very basic indicator whether or not you've used too much limiting, not to mention just being a visualisation.
So, don't use Winamp to judge how much bass you need. Either buy yourself some very expensive monitors and turn your room into a studio with bass traps etc., or just use a spectrum analyser such as the one included with Sound Forge, and become famliar with at what levels each of the frequencies should be. That is, 0 - 16 Hz should always lie between -60 and -90 dB, while your bass range of 49 - 98 Hz should typically lie around -15 dB (I usually like to have it a little under this line, at -16 dB or so). The bass should then roll off from the highest point (which may be 58 Hz or so) down to between -60 and -90 dB at 16 Hz.
Note that these dB values are really only applicable once you've compressed and limited your track, so this makes things more complicated. Give me a link to the track in question and I'll check it and let you know if it needs adjusting at all.
