I’ve had this sub hooked up to a 1200 watt amp for 2 and half years now and it’s still kicking strong. I’ve been contemplating Dynamatting my trunk to keep it from rattling at certain frequencies. There are two connections for your speaker wire and the first one I had it hooked two went out about a year ago so I swapped to the other one and it’s been going since. Definitely worth the $30 some odd bucks I paid for it. I wasn’t expecting it to last more than a year.
