Conclusion: I've had this sub for well over a year now and I love it. I have it running at 1000 watts RMS on my Hifonics amp and it pounds. I originally bought a premade box from sonic that was only 2.3cuft sealed and it sounded pretty good, but not as good as I thought it should.
Conclusion: I bought this sub used in a 1.4 cu ft box and at 325w rms. All i have had the money to do was build a box so far. Built a 3.8 cu ft ported box tuned to 38hz and holy moly! Still being 325w i compete with my friend that has 2 Rockford Fosgate P2's at full 1200w rms, I flex my door panels.
Conclusion: I've had this sub for about 8 months now, and that works very well. The only problem I had was finding the right box. Ended up getting a pro box just because it was the only box that didn't give the bass a dead sound. Also powered mine by a Boss 3000 watt amp.
Conclusion: I have two of these subs in a ported box hooked onto a Hifonics Brutus BRZ2400.1D amp. They sound great and provide a lot of bass! Would recommend them to anyone out there that wants quality sounding bass. You can definitely hear these from blocks away!
Conclusion: Man, these woofers are incredible. I'm sort of new to the car audio game but I know deep, clean bass when I hear it. It took nearly a year for me to save up but now I have: - 2 of these monsters - 1 Hifonics COLOSSUS - LTD 3200w RMS - Audio Control "The Epicenter" - 4 Kenwood KFC -6994PS 6''x9'' - 1...
Conclusion: I purchased this item a few weeks ago, it came in about 3days. It came with the box I ordered. I wired 12AWG wire in box and have 10AWG wire ran from amp to box. i drive a Buick Reatta and the box didn't fit it the trunk so I put it behind the passenger seat.
Conclusion: I have 2 of these on a 11zx2500.1 They take all the power it can give out. I know that everyone knows when im coming down the street with them. :) Sounds good in a sealed box. But im sure as soon as i get a ported box, will be alot louder. looking forward to that day
