I had them metered at a local car audio shop that my friend owns, and they were putting out 148.7 db in my Civic EK hatch, although this was before they even had a chance to break in yet. I'm not sure on the numbers anymore as I have moved and don't know anyone with a db meter. I have run them on a 2200 watt amp for well over a year, and have had zero issues with them. Currently have them hooked up to my home theater, but I'm looking to part with them to finance my next project with 2 18" subs for my Bronco. These are very power hungry bastards, but they will sound very good even on a lower wattage amp (but 250 watts is the least I would put to them.)I'm asking $250 for the subs and box. If interested, please email me at thadoggma@q.com, or call 503-896-0963.
