Hey I'm looking to run two Loaded BL 15s.  Will these hold approx. 1700 rms each? for light daily use and some compeition use as well?  Also is there a tuning frequency that I can get where they will drop hard and still be loud on about 45 hz tones for comps or do I need to just build two interchangable boxes?  What size would you reccomend if I'm driving a Jeep and have a lot of room.  This is a crappy first thread I know but I am looking for advice direct from the Fi experts lol.
