Features
Power Handling: AudioControl describes the continuous power handling (RMS) as follows:
- Min: 200 watts
- Ideal: 350 watts
- Max: 500 watts
Terminals: The spring post terminals accept pin connectors, single and dual banana plugs (standard ¾" wide dual banana plugs), and bare wire up to 10 gauge.
Grille: The removable grille is mounted under the rubber gasket/mounting-ring. With the grille in place the sub's mounting height is approximately 1½".
Sealed Box Volume: The recommended sealed box volume range is from 0.25 ft³ to 0.75 ft³, with 0.5 ft³ being the ideal size. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.
Ported Box Volume: The recommended ported box volume range is from 0.5 ft³ to 1.0 ft³. The ideal size is 0.9 ft³ with a slot port measuring 10" x 1¾" x 28", resulting in a tuning frequency of 40 Hz and a -3 dB point of 34 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.

I put this little 8" in my F-150 under the rear passenger seat. Paired it with a 350 watt amp and a premade forward facing box I bought on eBay. It bumps! I tried getting away with the Rockford Fosgate powered sub behind the seats but it's just wasn't cutting it. I love this sub!!!
