I checked out the 13Av.2. How do you guys rate this sub against a 12 w7 looks massive. Will the haxo lxo be better. im really considering purchasing one. i have a ppi pcx2400 amp its says it will do 1600 rms bridge @ 2ohm. or do you have any other suggestions. i want to be loud, alarm setting, shake windows , and if possible sq wouldnt hurt. ive also looking at hd3c aq, stroker, L7,fi, re sx, eighter 12 or 15inch. i have a 12 ported box already but if the fifteen is better ill go with that. ill be getting my Stimules check in june and want to help the economy by buying a sub.
