Aftermarket headunits work fine, also.
I did the same thing i had two infinty subs to go with teh stock system. The same day i got them finished i turned it down to the lowest setting cause it hit hard. They werent even that great of speakers i got them both for about 94 dollars at bestbuy. It also depends on how loud you want it. i now have 2 14 inch rockerfausgates in it now cause i go to compations and it hits hard. I all ready replaced my back windshield once.
