Alpine 600 WATTS RMS (1800 WATTS PEAK) type-R Subwoofer SWR-1043D 10" inch double coil 4 ohms *

Hi. Selling this great powerful subwoofer with custom build box. I have had this speaker for less than a year. I am very satisfied with that speaker. None of my friends have stronger subwoofer :D I build specially designed bass-reflex box for this speaker myself. Speaker is double coiled, each coil has 4 ohms so you can bridge it to 8 ohms. I am running this speaker on a 1600 RMS WATTS (3000 WATTS PEAK) amplifier which is also for sale Box dimensions: H = 46 cm L = 60 cm D = 30 cm approximately, I need to go to my car and check once again speaker specs: http://alpine-usa.com/product/view/swr-1043d/ Also selling Alpine radio and amplifier Hifonics Brutus that is 1600 RMS CHECT THIS OUT: http://www.gumtree.com/p/cars-vans-motorbikes/hifonics-brutus-bxi1608d-1600-watt-rms-3000-peak-amplifier/106725418
