I got 2 10in KICKER CVR subwoofers in a Logic Q Pro BassBand Box. They've only been used for about a year as I had them in my Civic that I no longer will be having & were barely pushed by a 300RMS Kicker Mono Amp so they're in perfect shape. I know they're rated at 300RMS & if you know anything about these they get LOUD. Let me know if you got any questions. Also got a couple amps I'm trying to get rid of too.
