Digital Designs DD Audio 608d 8 Inch Subwoofer & Q Bomb Enclosure

I am selling my 8 inch DD Audio 608d subwoofer it has long throw dual 4 ohm voice coils, double stack magnet driver, and back plate coil gap venting. It's 800 watt rms and 1800 watts peak power. I have it installed in a Q Bomb ported enclosure it's a little ugly cause it was meant for a 10 inch sub so I made a adapter plate so I could mount my 8 in it. The subwoofer ran me 220 and the enclosure runs for 90 bucks. I would be interested in trading for other subs, enclosures, amps, speakers, ect. I also have a pair of Alpine Bassline 12s (w12s4) that I bought a couple months ago and they don't have a enclosure right now and the price reflects that and will go up of I get one for them. They are single 4 ohm voice coil 750 watts each. They sell for 220 on Amazon where I bought them and would like to get 140 for the pair.
