from what i can tell from google its more of a vocal speaker and not a subwoofer four 65 watt guitar speakers? i don't think it'll give you the sound your after because its a concert hall type speaker but regardless if i were you and i had my mind set i would go for a four channel amp with a full pass crossover and just wire them up individual. they are not subwoofers. 65w x 4 so go with 200 watts max. running them as you would subwoofers will probably blow them up fairly quick. if i were you and wanted more bump i would thank my neighbor, wait a week and sell them and buy a single 12 and an amp something to throw it in the trunk real simple. or get some drop in speakers if you don't want the boom just better sound. or buy a guitar
but seriously at $165 new you could probably sell them to someone.
