This product is GREAT. I have a SINGLE cab '87 Ford Ranger, custom built box and it fits. The box has bout .7cu ft and i have it wired at 2 ohms, pushing 550 watts to it. This subwoofer SLAMS. People are amazed by how loud it is, especially for ONE 12in SHALLOW mount. I hit the lows very easily and the highs will impress you. A very good unit to purchase!!

I have an extended cab F-250. As some are probably aware, there isn't a ton of room in these trucks.

I built a box to MB Quart's spec..... and these subs do not disappoint in small sealed boxes.

Customer Testimonial

I started to replace some equipment in my boat and ended up replacing just about everything from amps to a new head unit. Everytime I had a question or wanted some advice your sales reps were always very patient and helped answer all of my questions. The shipping is exceptionally fast!
