I dont know what would be best

hey guys i have a 2004 tahoe and im wanting to make it a little bit louder. Ive been around car audio for awhile but just kinda getting back in the groove of things stopped for a little bit because other important things started happening but i have always loved it and it draws me back over and over to rebuild and get louder lol

right now i have 2 fosgate 15s

my question is should i just get 4 more to have 6 of those fosgates or should i get 4 SA- 15s

right now i have a audiopipe 3k powering them so thats the amp i would use and get a second one for more power or a third if need be with the 6 fosgates

i like the fosgates but what im wondering will 4 of the sundowns out preform 6 of the fosgates

it would be cheaper for me to get the RF'S but i would spend the extra money if it was worth it

let me know guys
