ok guys im going to get the fi q in a 12" with a hifons bxi1608D amp and im just gettin 1 sub... im getting it this summer but next summer i might upgrade to another... what should i do for a subwoofer box for now should i get a good one so if i dont want another sub i dont need another box... or if i do get another sub get a single sub box then ill have 2 or get a dual sub box... im getting the boxes made from fisher customs.... will the hifonics amp power 2 subs good? and do you have any other or more suggestions
