Alpine SWR-1521d
Its the older type-r model. Dual 2-ohms. Sealed in a 2 cubic foot box. This sub will run at 1 ohm or 4 ohms. Obviously most amps arent stable at 1 ohm so you have to have a pretty big amp to run it at 4 ohms at 500 watts rms. I have no use for it anyone who can use it can have it. I can take a pic if needed. Physical condition is fine and sounds great. Cosmitically isnt not perfect but doesnt affect the sound.
Pay shipping and its yours.
