Breakdown the ohms

[RufusExpo]

Only In America

Hey Ruf here trying to figure out some info fo my expo, subwoofers, i had 2 kicker 12s comps ( black and yellow) had them hooked up to 1000 watt amp and was killing anybody with anything until i blew them lol, i have always had kickers thats my favorite brand i have been threw 3 sets of the Comps, these are my questions.

I have a good understanding of what is what..

Alpine mono block 1000 watt amp

-The lower the ohms the better the bass is that true?
-If i wanted to run 4 comps would my 1000 watt amp be good enough for the kickers?
-Would i use 4 ohm or the 2 ohm kickers if i did 4 comps?
-What would i use to keep it from killing my battery and making my lights dim?
-I have tweeters and my other speakers hooked to a 300 watt jensen, would i need to add the one to it as well?
-Would i need a stronger alternator? 130 amp? instead of 90 amp or whatever the stock amp rating is?
-would i also need a stronger battery? maybe a interstate battery or optima? the duralast red battery i have dies every year and i have to return it and get a new one, (i dont like it).

any tips help!
Thanks
