The sub is in great condition. 10" woofer. Fully functional with a strong amp. It turns on and off automatically or manually anddelivers plenty of tight, punchy bass. Can be connected to newer or older amps. Very versatile and easy to integrate with any system, even if your amp doesn't have a designated Sub Out connection. Clean grill, smoke free home. It's currently sold on Amazon for $249. Asking $75. Text Alex @ 801-833-3608
