I am currently replacing my two Exile Audio Pro xd12's for 2 Sundown SA-12. The feedback on sundown has been amazing and am really looking forward to hearing them. I am on a budget and want to get the best out of the llittle cash i have. I will be running these SA-12 off a Rockford P-1000.1 amp until i can get a bigger and better one. My question is the enclosure. A custom enclosure for 2 ported is quite a bit of money over here, so i am looking for a box i can find to order than is close enough to specs to sound good. Does anyone know a good enclosure to put these 2 SA-12's in that will sound good?
