well new xfls are 300+ for current year, or you can buy offline buying the previous model for $160
really not that much of a difference. but you wont have a warranty as bob does not allow online sales and will not acknowledge a web sites warranty.
a lot of people talk bad about american bass. probably because majority of the people who dont know anything about them live in west usa.
i have tried
memphis
earthquakes
kicker
american bass
orion
rockfords
and by far i think the 2 that outdoes all for price of them are american bass and memphis
i have 2 american bass xfl12 on a 150.1 ab amp they slam pretty hard for being in the trunk as well.
bob hit 175+ db on a single xfl 18 but thats an 18. i think youll be pretty happy with 1 xfl 12 paired up with a good amp and proper electrical and box tuning.
