i have 2 12" memphis power reference subs in a sealed box...with a cheap mdx 1200watt amp. my homeboy will sell me 1 15" l7 for $20...is it possible that it can be louder then my setup?? with what amp if so??
yes it will be. they are only spl subs and will get loud. if you put it in a ported box tuned to around 35-38 hz, with a mb quart raa1000, or memphis 1000, hifonics 1206d, jl 1000/1, it will def get loud
