I have 2 of these bad boys in a custom made ported box with a punch BD 1500 on them all I have to say is awesome can not get any better for the money I love this setup!!!!

I have a single Alpine SWR-D4 in a custom ported box driven by an Alpine MRP-M500 amp pushing 500 watts at 2 ohms. This amp and sub setup is awesome, I listen to rap, rock, metal, and country, this sub has great frequency response with anything you throw at it. It hits so hard in my 2004 Chevy Impala, it pretty much gives you a back massage. Definitely a good value for a good price. Will definitely purchase again>
