no way to tell. theres so other factors that come into play. Only way to tell is to go and see for yourself. but if i were you i'd go with the avalanche. Im sure it'll be loud enough for just about anybody.
ava's are amazing subwoofers, 2 12" Atlas are about identical as one 15 Ava. Its up to you what you choose, space or looks. I choose looks and my setup sounds amazing with the 2 atlas, Hits every beat and gets sickingly loud when the demand for power is at hand. The ava are to me, a more competition, but not competition subwoofer. They produce amazing bass and hit HARD. For a daily driver i dont see why you would need more than 2
well if i were to get 1 ATLAS 15" from AA is it going to be able to get pretty loud? because i heard its mainly a SQ sub.. and i wanna get loud but not for alot of money-- so is it gonna be loud or just middle of the road loud
