[QUOTE="ecs1965, post: 8680175, member: 677616"] I have two of the first gen ALPINE R's SWR-1221D 2 OHM pushed by there own MRV- T420 THEY STILL HIT AS HARD AS THEY DID WHEN I BOUGHT THEM BRAND NEW IN 2004. I STILL HAVE THERE BOXES ORIGINAL PAPER WORK AND RECEIPT. That's a good by any sub+box+amp. And as for the box sealed or ported it is close enough to the specs of the sub it will be ok it will still perform like it should. I'm putting an ALPINE OLD SCHOOL SYSTEM in my F-350 Super Duty I got 2 ALPINE R-W12D4 IN A CHERRYMAN CUSTOM ENCLOUSER POWERED BUY ALPINE MRD-M1000 W/C RUX-4280. [/QUOTE]
