Whats up, here is deal, i sold all my subs and amps few months back, thinkin i was out of audio. Now i am using my same box, just putting new baffle on it. It is a little over 8 cubes after port displacement tuned to 34hz. I usually just drive car in winter and when raining so i dont want to spend fortune. But anyway, i looked at running 18" BTL or BL. I will only be running a crossfire vr1000d, birthsheet says 1300 watts at 1 ohm at 13.8 volts. I have kinetik under hood and kinetik 2000 in back. What suggestions do yall have? I listen to anything from country to metal to rap. thanks for any help

oh yeah, i may even sale crossfire amp and go with sundown 1500 if it would make any difference.

If you pickup the sundown then the BL series would probably work best...

Thanks
