there is some one selling a Exodus Audio Maelstrom Gen. II 18 dual 2 ohm sub by me and i a few questions about that sub. first has anyone else put one of these in a vehicle cause most use it for home audio. second what would be a recommended box in a 01 tahoe, sealed or ported and what cuft? i have a jl audio 1000/1 sub amp to power the sub will this be ok? i appriciate any help. i have 3 jl 12 w3v3s in the truck now and it just doesnt do the lows like i want. will the maelstrom blow the 12s out the water or what?
