Buy the 750 kicker , the kicker amp will put out over 750 tho so be careful , you may also get away with just a 500.1 , I have never herd of subs with a 100 watts differince I'n rms from norm to peek it's usually 2x the norm
Yea man , research and go with the mainstream brands and you won't be let down , and build your owne box ;-) , or get out of car audio while u can , it's like a drug once u start u may not be able to stop
Yea get small 750,1 kicker amp and a 12" l7 or something along those lines check eBay man shop around , I know hifi audio sells kicker referbs for cheap
That's pretty crappy , if that amp does what it says pigs fly , try a well known brand maybe you pay more but you get what it's rated , look for cea rating , good luck dude
