    ok right now, i have 2 12" polk DB's (Dynamic Balances (discontinued)), and a Kenwood KAC-728 powering it...
    NOW MY QUESTION IS...is the amp i have right now enough for my subs? or can i go even bigger to make them pound harder? if, i can get a bigger amp, please give me some suggestions...most of the suggestions if have gotten were towards either a JBL 1200.1 or a 600.1 (mostly 600.1)...thanks

    these are the specs for one 12" sub...

    Unfortunatly it is hard to tell. The actual power able to be handled by your subwoofers really does depend on your enclosure, listening tastes, and length of time you plan listening. With 100watts, you are already probably able to get your subwoofers to their max output when you clip your amplifier, although that really depends.

    You would most likely be able to get your subs to play louder with a new amplifier, but then you will have to worry more about destroying them from overpowering.
