this is a rare find from japan. alpine made a series of products for japan and so did other car audio brands.

they were better and more expensive. this is a mint condition, alpine SWF-304G

which is a 12'' sound quality woofer with a copper bottom and a cast basket. it is a single 4 ohm woofer and will

handle up to 600 watts. as shown in the pictures, it is in great shape and it ohms out at 4-ohms. 

this woofer sounds great and it sounds better than any other alpine sub that i have heard. 

it reminds me of focal subs. 

this will ship for free in the lower 48 states and hawaii and alaska will be more so inquire before purchasing.
