Thats a nice setup on the CDT speakers packaged deal..I run cdt, and Polk at the moment in one of my vehicles..I cant say enough for a speaker for the price..Very Pleased,,Keep up with my 1k rms 10s right now..approx 900 true rms per sub, maybe more??Yet Im running,some Briaxels up front, replacing a set of tweets with Kicker KS25, and placing my CDT CL-60 components up front, and getting those 5.25/100rms woofersPolk MoMo out,.The Briax keep up pretty decent,but Im needing more mid up front..Difference is my Subs are in the cab with me, so You may be just fine if you are placing the subs in a trunked area.Its all trial and error at this point, as to who can actually say that any brand of speaker can keep up with your subs, until, you trial run.?Im needing a bit more up front for myself/yet, thats just me,.Others believe its fine, but everyone has a different perspective of sound itself,and liking.
