Posted October 20, 200717 yr 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.
