yeah it really depends what sound you want, power handling. Unfortunately the expensive Kicker 15" L7 solbaric did not produce the same sound as my 15" Rockford Power T2. Even though both subs rms handling was 1000rms, the T2 sounded better. But, we need to know what your looking for as in Impedance also. My Kicker L7 was DVC 2-ohm, bridged to 1-ohm, my 2 fosgates are DVC 4-ohms bridged all to 1-ohm.
We need more info.
