First is a nice Image Dynamics IDQ12. Believe this is the V1 version, has dual 4 ohm coils. This is a wonderful sub that I never expected to sell, but I'm happy enough with my Matrix Elite 10 and the small box it requires to finally let the IDQ go. Decent cosmetic shape for a used sub, functions 100%. Truly lives up to its reputation. I ran it with the coils in series in about 1.25 cubes sealed with some low end boost and loved it. $80 delivered in the Continental US.
Also am letting my PG QX500.1D go. I'm the 2nd owner of this amp, it's extremely clean. Cosmetically I'd say certainly an 8.5 and possibly a 9-. I originally planned on running this with the Soundstream Rubicon Picasso I sold last week, but I've moved up in power to a Hifonics VII Olympus and a Rockford T5002. This amp works well and is quite powerful, but the noise floor seems a little high - a slight noise can be heard if you put your ear up to the woofer cone with no signal present. Not sure if this is characteristic of these amps because it's always done it since I've owned it. Might be an issue if you have a center console sub or in a small hatchback with the car not running, but I doubt you'll be able hear it in the trunk of a sedan or with the engine on. The amp is otherwise working well. 275x1 into 4 ohms and 500x1 into 2 ohms. Subsonic filter. crossover, boost. Two 40-amp fuses. $100 delivered in the Continetal US.
Send me some PM's!
