Sub woofer for 2005 LW

[Zephyr]

Well, since it doesn't look like I will be replacing the head unit any time soon, I guess I should make the best of it for the moment.

 

 

Anyone have experience with the current sub woofer available from Subaru?

Is it a good unit or can I do better somewhere else. I'm hoping to stay at or under this $188 price.

Thanks!
