should i put an 18" btl powered by a hifonics bxi 1606d with an 8 cuft ported box tuned at 30 hz and later upgrade to an mmats d3000.1 and upgrade my charging system (when i get the money lol), or should i get 2 15" FiQ's powered buy 2 bxi 1606d amps (or do i still need to upgrade the charging system?) i just dont know any isuggestions would help, space is not a problem its going in a 99 jeep grand cherokee.
im thinking also about just one 15 q with the hifonics 1600 i can get into that for just over 500 i just dont want to be dissapointed because i have never heard one before
