Audio Systems: should i do a cap or another battery, playback system, music playback

Question
I have two pioneer imp subs that push 800 watts each with a an rms rating of 300 each, i am then running a 750 watt 2 channel amp that is bridge for the most power, im getting a slight light dim when the bass is hitting bt other than that no problems, also i am thinking about putting in a 350 watt kenwood amp to power my components do you think i should instal a cap or another battery to power the system

Answer
Think about it:  A cap is not an energy source; it merely smooths out the power take from the battery whereas an additional battery brings more energy to the system.  

Therefore, I vote in favor of another battery or a bigger, more powerful battery in place of the one you know have.  You may, also, need a heavy duty alternator to keep up with all the power you are going to need to keep the amps alive and well.

It is worth it; there is nothing more exciting than good, solid, earth shaking bass added to a realistic sounding music playback system!
