Want new subs thinking of kickers wat should i do?

good luck getting that for under 400...

the setup you have right now is probly right near that mark.

kickers do pound and stay intact pretty well except the squares which tend to come apart rather quickly...
if going with kickers i'd say some xpl's but they are going to cost ya. and the amp... i bet you cant even find any 800W (decent quality) for much under $400. so if thats the absolute limit in $$'s stay with what you have or just upgrade one thing ie the subs or the amp or whatever.
custom box minimum 80.00 unless you do it yourself.

car show bass is minimum 2 speakers(many more usually cause the one's you could get away with just two are like 1000 bucks each.)... total sub wattage about 1500W-sky's the limit.

i hope i didnt put a damper on ya... but 400 is just not reasonable for car show bass.
