DB DRIVE K5F12D4 12-Inch Okur K5 Series Flat Subwoofer

Damn. If you know what you're doing, these are incredible subs. Running two on a ct 900.1 @ 1 ohm. Single cab truck(05 gmc sierra) custom sealed box behind my seat built to recommended specs (speakers specs say these specific subwoofers are not recommended for ported enclosures.) They hit good lows to about 28-27 hertz clean and highs up to 50-60. If you are restricted on space, want to be loud,(with highs and lows), and are building on a budget, you honestly couldn't go wrong.I'm about to put a 3rd one in my truck wired down to .67 ohm.... Very excited. #ijwb

I have 2 of these in my Honda Accord in a rhino box and they. Quake!!!!

Great

I have two of these in a 06 Nissan Titan wired at 2 ohms downfiring on a 1500rms hifonics amp. These subs can handle what ever you throw at them from deep low rumbling gut punching bass to high end driving bass.
