Totalled my car a while back, this has been sitting in my garage ever since. I've used it for less than a year, its in perfect condition.12 inch alpine type R Dual 4 ohm in a sealed enclosure, with a HiFonics Brutus 1200watt amp, and 1.5 farad capacitor. The sub handles 500watts RMS and 1500 Watts MAX. The amplifier matches up perfectly with this amp. Box dimensions are 13x13x16 inches. I spent about $600 on this setup, but I really need the money now so im letting it go for only $375 ... NOW $325. Pickup ONLY. Located in Glendale, CA.
