I am currently in the process of trying to build my own crossovers for one 6" bazooka tube, two 8" rockford subs, and two 15" lightning audio subs. I want to know if i could run them all from a single rockford bd1000 mono amp. all of the crossovers are 12 db per octave and i have designed them each specifically for the resistance from the set of subs that they will be running. does anyone think i will have any trouble doing this, and if so, what? thank you for your time and your help will be appreciated.

Hi Eric, keep in mind that impedance is relative to frequency and as long as you do not drop below the amplifier's minimum stable impedance rating over the range of frequencies you'll be filtering to each of the subs, you should have no problems running all of them off of any amplifier.
