As the title reads, I am building a sound system currently I have a set of mb quart 5x7 onx157s and hypnotic zen 6.5 components. Head unit is a kenwood ddx319 amp will be a massive audio nx5 or kicker zx700.5 I am torn between several subs: image dynamic IDQ10, diamond audio D610 or a massive audio kilo 104. I am looking for sq and want a sub that can play well in all types of music. Any help would be appreciated.
