I have the MOJOs right now ran by a Hifonics Brutus 2100.d. Now i know thats not enough for them but in general with a custom box and either same amp or a saz-1500, could i get a little louder with the sundown SA-12s since ill actually be putting enough power to them? Also this would be in a 2000 ford explorer, so if anyone has witnessed a similar setup with 2 sa-12s in a explorer it would be great if you give feedback. thanks
