hey,Right now ive got some cash and i need some subs, preferable Type r's and i would either want an alpine sub so i could go all alpine or a JBL600.1 amp. I was jus wondering wat stuff i should go with, like which type R's and wich alpine. Right now i got an alpine 9827 deck and 4 speakers in my car and i would like to go all alpine, unless the JBL would be better then any midranged alpine amp. i drive a nissen maxima if that makes a difference.
