It will work just fine for your install. The only reason I wouldn't run the new ones is because they aren't the same overbuilt tanks that they once were. Sadly, this can be said for about 90% of the "American" car amplifiers that are now made overseas //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
My only recommendation would be that you take precautions to isolate your amplifier from extreme vibrations if you can. In other words, don't mount your Hifonics amplifier directly on your subwoofer enclosure without using some sort of rubber shock mounts!
