Obviously, you know way more than heyman421 does, care to explain what Jack Bauer will need?
If he is looking at just a good quality system, i probibly would not recommend the SPL Premier that i have. Its not exactly 100% quality when really pushed, there is some distortion at very high volumes, but unless you listen to your music maxed all the time, it probibly wont be a problem.
And yes, that is the same subwoofer and amp i have now. Im actually getting a new dual 12" enclosure to fit another Premier with a second HiFonics amp. I have been VERY pleased with my setup, its certainly not the loudest, but it turns heads. It sounds great at normal listening volume as well (i usually listen to my music at 30-35/50 with the subwoofer on 1/4 gain).
And i have no cap, stock alt (rated to put out 95amps). Just 2 amps, a distribution block. i have a 100A fuse up by my battery (im soon upgrading to a 200A alt.)
Bottom line is, HiFonics is a well known brand, and highly respected in car audio, subwoofers AND amps. Even their low end stuff has great reviews, your actually the first person i know of that has talked down HiFonics like this. It may have just been you had a bad amp, it happens. All i know is mine sounds great, stable at 1 ohm full gain half bass boost, and it really pushes my Premier to its max.
And dont go sealed on the enclosure. Its always best to build your own, but i wouldnt just buy something that doesnt tell you what its tuned at. For the Premier, my box is tuned at 32hz and it sounds great, its made to hit them REALLY low notes. Flexes my windows and i even get some minor windshield flex at the right note.
