Silver bullit,
How did those Kickers toast on you?
They are very durable woofers.
What were they crossed over at and what type of enclosure were they displaced into?
Btw, the Sony X-PLOD subs are truly considered one of the best bang for the buck woofers, especially at 300w rms and 900 watts peak.
Save a few more dollars and that will open the gate for a larger variety of subs.
Most importantly, are you into spl or sq?(sound quality)
