If I were doing it over again i would go for a single 10 maybe an IDmax or IDQ or 10W6 on 6-700 watts, my setup is just stupid, too much bass. Also if you have too much bass the whole car will rattle, Still trying to figure out how to stop the rearview mirror from rattling, really sounds obnoxious.
Do you have a budget in mind? don't blow your cash on subs and neglect the mids and higs and their respective amp(s)
No budget really but I'd like to keep it between $1.5k to $3k
