I have a Sundown SA-12 D4 for sale.
: 600-1000watts rms
Asking Price is $200
I have 2 12" Sundown SA-12 (D4) for sale. I bought them brand new around 6 months ago. They were powered by a MB Quart DSC1500 (which I can bundle with the subs) and saw around 600 watts each (they are rated at 600 watts RMS but they can take 1000RMS at no problem but these have never seen more than 600 watts).
$200 each. I can ship them (at your expense) or meet up with you if you're from the Vancouver area. I paid around $700 for them brand new from woofersetc. $400(subs)+$100 shipping+$150 brokerage(rip off)+$60 taxes
The MB Quart DSC1500 (1500@1ohm) is $200 on its own or $150 with the subs. It does rated power and sounds great its one of the most popular amps on many car audio forums.
I also have a custom dual ported box for these 4.0cu ft tuned @ 34hz they sound bad *** in it I would want $150 (with the subs) $200 (without them), if you want it shipped it would cost at least $100.

Edit: Here are the pics. Subs are a little dusty they have been out of my car for about 2 months. As you can see one has a small nick on it but its been repaired and does not effect performance.
