American Bass XO 15” Subwoofer – 500W RMS Dual 4 Ohm

Sold by AudioSellerz.com

The American Bass XO 15” Subwoofer is a big-cone, budget-friendly banger designed for daily builds that still want serious low-end. Rated at 500 watts RMS / 1000 watts max with a dual 4 ohm voice coil (D4), the XO 15 is perfect for trunk and SUV systems where you’ve got the space for a 15 and want strong, musical bass without stepping into high-end pricing.  

A 2.5” high-power 4-layer voice coil, 125 oz stacked magnet, and stamped steel basket give this woofer the motor strength and control to handle real daily abuse. Sensitivity is listed at about 89.9 dB, so it wakes up nicely on a solid mono amp and responds well in properly tuned ported enclosures.  

With a 7.1” mounting depth and 13.9” cutout, the XO 15 drops into most standard 15 inch box designs. American Bass recommends ported enclosures in the 2.75 – 3.0 cubic foot range, which lines up with typical street-bass tuning for deep, impactful low-frequency output and long-term reliability.  

The dual 4 ohm coils make wiring flexible: a single XO 15 can be wired to 2 ohm for most Class D monoblocks, or you can run a pair of XO 15s on a stronger amplifier wired to 1 ohm (with proper electrical upgrades). Matched with a clean 1000–2000W RMS amp and a solid enclosure, this sub is more than capable of real “window-shake” daily bass.  

If you’re building a value-minded system and want a 15 inch American Bass subwoofer that hits hard, takes power, and keeps wiring simple, the XO 15 is a solid choice—and it’s available now at AudioSellerz.com
