but i think the bass might be to low for somespeakers
When approaching to the mixing stage, you should consider the limitation of most speakers.
Most speakers are not able to produce frequencies below 40-50Hz.
now that you know that, you know you can cut those frequencies. the speakers wont be able to produce them, so why let them take space in the mix? (and they take alot!).
do a 24/18 low cut from about 30Hz. than take a band to the 75Hz area and boost it up with a wide Q to get the fatness back.
same thing with the kick. only the boost should be around 90Hz insted of 75. personaly, i also do a low cut up to 40Hz so the kick wont fight for space with the bass.
